Design Principles and Functions of Sliding Bearings

Sliding bearings, also known as plain bearings or journal bearings, operate on the principle of providing a low-friction interface between two moving surfaces. The design of sliding bearings is based on creating a film of lubrication between the bearing surface and the shaft or journal it supports. This film of lubrication separates the two surfaces and minimizes direct metal-to-metal contact, reducing friction and wear.

The main components and design principles of sliding bearings include:

  • Bearing Material: Sliding bearings are typically made from materials with good wear resistance and self-lubricating properties, such as bronze, brass, or various polymers. These materials help reduce friction and prevent excessive wear.
  • Lubrication: Lubrication is crucial for the proper functioning of sliding bearings. It can be provided by an external lubricant, solid lubricants embedded in the bearing material, or a combination of both. The lubrication forms a protective layer that reduces direct contact and minimizes friction.
  • Clearance: Sliding bearings are designed with a specific clearance between the bearing and the shaft to accommodate the lubricating film and allow for proper movement. This clearance prevents seizing and binding of the bearing.
  • Load Distribution: The design of sliding bearings ensures that the load is distributed over a larger surface area to prevent excessive stress on any single point. This feature is essential for handling heavy loads in industrial applications.
  • Alignment and Misalignment: Sliding bearings can tolerate small misalignments between the bearing and the shaft. This flexibility allows them to accommodate minor shifts caused by thermal expansion, vibration, or other factors.
  • Heat Dissipation: Sliding bearings can generate frictional heat during operation. Proper design includes features to facilitate heat dissipation and prevent overheating that could lead to premature wear.
  • Application-Specific Design: The design of sliding bearings can vary based on the specific application requirements, including load capacity, speed, operating temperature, and environmental conditions.

The functions of sliding bearings include providing support to rotating or sliding shafts, reducing friction, absorbing and distributing loads, allowing for misalignment, and offering smooth movement even in dirty or contaminated environments. Sliding bearings are commonly used in various industrial machinery and equipment, including engines, pumps, conveyors, and manufacturing equipment.

Overall, the design principles and functions of sliding bearings make them suitable for applications where low friction, durability, load-bearing capacity, and adaptability to varying conditions are essential.

Types of Ball Bearings

There are several types of ball bearings: Double-row angular contact, Four-point contact, Self-aligning, and Ceramic hybrid. Here’s a brief description of each. For more information, read our article about Double-row angular contact ball bearings. You’ll be better informed about how they’re made. Also, learn about how the cages that hold the balls in place are secured with rivets.

Double-row, angular-contact bearing

Double-row, angular-contact ball bearings are similar in their contact surfaces in one direction, and the two pairs of bearings are installed axially opposite to one another. This design allows them to support combined loads in axial and radial directions. These types of bearings are used for high-precision, high-speed applications. They can be used in everything from turbines to dentistry equipment. Double-row, angular-contact bearings are available at Grainger, as are single-row versions.
Double-row, angular-contact ball bearings are a popular option for applications where high precision and high speed are required. The design features of these bearings are ideal for applications with axial space restrictions. In contrast, they are smaller than two single-row angular-contact bearings and are available in steel, polyamide, or brass cages. Whether you need a cage for high speed or hard operating conditions is up to you. If you are unsure about the right cage for your application, contact Schaeffler.
Single-row angular-contact ball bearings are the most common type of bearings. Double-row bearings are also available with a shielded outer ring, which protects the balls inside the bearing from external contaminants. Because these double-row bearings are a good choice for applications requiring high performance, they are often the most affordable option. They offer similar performance as single-row bearings but are much more rigid.
Preloading is a key performance characteristic for double-row angular-contact ball bearings. Preloading can decrease the service life of double-row angular-contact ball bearings by up to 380 percent. Alternatively, you can preload double-row angular-contact ball bearings by placing spacers between their outer rings. Good double-row angular-contact bearing installation will increase working accuracy and bearing life.

Four-point contact ball bearing

The Four Point Contact Ball Bearing Market can be segmented into three types: 35 Degree, 45 Degree, and Other. The 35 Degree segment is expected to witness the fastest growth over the next few years, owing to its increased operational speed and competence in axial and radial axis load handling. Other types of four-point contact ball bearings include the Miniature and Deep Groove varieties. These are widely used in automobiles, aerospace, and other industries.
These bearings are designed for oil-free screw compressors, and they feature an outer-ring guided brass cage to reduce friction and increase running accuracy. In addition, they have lower maintenance costs compared to conventional bearings. However, they have a higher mean roughness value than their counterparts. High-speed operations require high-speed bearings that can withstand fast speed changes. This is because of the higher friction rate, which results from four-point contact.
The Four-Point Contact Ball Bearing is a highly versatile product, as it can handle radial, thrust, and moment loads. Because of this, it is often the first choice for slow to moderate-speed applications. This design also has a simplified assembly process, requiring only a single double-half-turn to install. It is the first choice of many automotive OEMs because it is extremely efficient. If you want a ball bearing with these benefits, you should contact a local bearing company.
The Four-Point Contact Ball Bearing Market will continue to grow despite a tough economy and volatile trade conditions. Demand for automotive and aerospace components is expected to grow alongside a variety of technological advancements. Meanwhile, demand for energy-efficient products will continue to increase with changes in trade policy, an imbalance in the supply-side ecosystem, and geopolitical risk. And while all these factors will continue to drive the market growth, a few challenges are worth considering.
The Four-Point Contact Bearing is designed with the same basic structure as its two-point counterpart. In a four-point contact ball bearing, one ball can have four distinct points of contact with two rings. Two of these contact points may be in diagonal position. The two remaining contact points change position and accommodate radial loads. Consequently, the Four-Point Contact Bearing is more flexible and robust than its two-point counterparts.

Self-aligning ball bearing

The self-aligning ball bearing is an incredibly useful tool in many industries. This type of bearing has a sealing lip that makes contact with a smooth chamfer on the inner ring. Because of the self-aligning nature of these bearings, they are not prone to misalignment. They can withstand temperatures ranging from -30°C to 120°C and should not be heated prior to installation.
A self-aligning ball bearing is an elastomer-based spherical-shaped bearing with two rows of rolling elements. These bearings can accommodate large radial loads, and their outer ring raceway is curved to provide a spherical effect. The inner ring, or cage, can be either cylindrical or conical. The inner diameter of a self-aligning ball bearing is normally cylindrical, but some are conical. They typically have three oil holes.
When choosing a self-aligning ball bearing, look for a model with a large enough bearing diameter to accommodate the shaft’s bending. Self-aligning bearings may also be interchangeable with standard ball bearing assemblies. You can find individual values in manufacturer catalogues. These bearings are useful in limited applications, although they are not necessarily ideal for everything. For example, in applications where combined loads are the main concern, self-aligning ball bearings should only be used if the application requires minimal misalignment.
A self-aligning ball bearing is a highly-efficient, energy-efficient solution for a variety of applications. It is a simple, low-maintenance solution that makes your life easier. Its unique outer raceway allows restraining springs to absorb the deflection that is common in other bearings. The result is a cooler, smoother running vehicle. It also helps prevent misalignment, which makes it ideal for use in many applications.
The SKF self-aligning ball bearing is an excellent choice for applications involving heavy deflection of the shaft. They are the lowest-friction bearing available. Their steel plate reinforced seals prevent them from separating from the shaft during operation. They are also resistant to oil, making them the perfect solution for high-speed applications. In addition to this, they are designed to work in a wide range of temperatures.

Picking the Appropriate Ball Bearing for Your Software

When choosing a Ball Bearing, there are many items to think about. These aspects incorporate: the size, lubricant kind, presence of corrosive agents, stray electrical currents, and much more. It can be demanding to select the right kind, size, and type of ball bearing for your application. You need to also cautiously determine the masses to figure out the right dimensions. Here are some suggestions for picking the proper Ball Bearing for your application.

Single-row

The single-row ball bearing is one particular of the most well-known types of bearings. The inner and outer ring are developed with raceway grooves that are shaped a bit bigger than the balls. This kind of bearing has a reduced torque and can handle large-speed apps with minimal energy decline. The radial proportions of single-row ball bearings also range, so it is achievable to discover one that matches your distinct software. In addition to the over-pointed out rewards, solitary-row ball bearings are also offered with various grease amounts and are widely applicable to purposes in which the place is constrained.
Solitary-row ball bearings are also known as angular-speak to ball bearings. Because of their one-row design, they are not separable and can accommodate a large-pace, hefty-responsibility software. Solitary-row angular-make contact with ball bearings can only manage axial load in a single course, and they must be set up in pairs for pure radial masses. One-row ball bearings are a well-liked type of rolling bearings and can be used for a vast selection of apps.

Self-aligning

The self-aligning ball bearing was invented by Sven Wingquist, a plant engineer for a textile organization in Sweden. Although he was responsible for making manufacturing as efficient as possible, he shortly understood that the machinery he experienced in area was not operating as proficiently as it could. Although ball bearings are excellent for decreasing friction, they have been not versatile sufficient to compensate for misalignments in the equipment.
Self-aligning ball bearings have two rows of balls and a frequent sphered raceway. The inner ring is curved and combines the two rows of balls into a single cage. These bearings can tolerate shaft misalignment and compensate for static angular defects. They can be utilised in simple woodworking machinery, ventilators, and conveying equipment. They are usually the chosen choice for programs the place shaft alignment is an problem.

Ceramic

A Ceramic ball bearing is a sort of large-overall performance bearing that is obtainable in both entire-ceramic and hybrid types. The principal distinctions amongst ceramic and steel ball bearings are their development, lubrication, and mobility. Substantial-top quality ceramic ball bearings are sturdy, and they are excellent for corrosive and substantial-temperature apps. The content utilised to produce these bearings helps avert electrolytic corrosion. They are also perfect for decreasing the friction and lubrication requirements.
Ceramic balls are more challenging and significantly less brittle than steel balls, which provides them a increased degree of rigidity. Ceramics also have a larger hardness, with a hardness of Rc75-80 compared to Rc58-sixty four for metal balls. Their high compressive toughness is approximately 5 to 7 occasions better than steel. In addition, they have a quite reduced coefficient of friction, which permits them to spin at increased speeds and with much less friction. This increases their lifespan and longevity, and decreases the vitality required to turn cranks.

Steel

Unlike standard bearings, steel balls have a fairly uniform hardness. Carbon metal, for instance, is 2.1% carbon by fat. According to the American Iron and Metal Institute, copper content material should be no a lot more than .40% and manganese articles should not be a lot more than 1.65 g/cm3. Following carbonizing, steel balls bear a procedure named sizing, which improves their roundness geometry and hardness.
The primary variances between steel ball bearings and ceramic ball bearings can be traced to their various components. Ceramic balls are manufactured from zirconium dioxide or silicon nitride. Silicon nitride is tougher than steel and resists shocks. The result is increased pace and lengthier service life. Polyoxymethylene acetal (PMMA) bearing balls are identified for their stiffness, energy, and tolerance, but are not as frequent as steel ball bearings.

Plastic

The most popular kinds of plastic ball bearings are manufactured of polypropylene or PTFE. These bearings are utilized in programs requiring increased chemical resistance. Polypropylene is a structural polymer that delivers excellent actual physical and chemical homes, such as exceptional resistance to natural solvents and degreasing agents. Its light-weight, low moisture absorption price, and good heat resistance make it an excellent decision for substantial-temperature purposes. Nonetheless, plastic bearings are not with no their downsides, specifically when functioning at quite large temperatures or underneath hefty loads.
When compared to steel bearings, plastic ball-bearings do not need lubrication. They also are very corrosion-resistant, generating them an outstanding option for clean-down programs. They are also put up-, autoclave-, and gamma sterilizable. Many conventional steel ball-bearings cannot take care of the large temperatures of foodstuff processing or swimming swimming pools. In addition to high temperature programs, plastic ball bearings are resistant to chemical substances, which includes chlorine.

Glass

Plastic sliding bearings are molded bearings produced of engineering plastic. With self-lubricating modification technologies, these bearings can be developed by injection molding of plastic beads. They are commonly utilized in various industries these kinds of as office gear, physical fitness and automotive products. In addition to plastic bearings, glass balls are employed in a assortment of other programs, including health care tools. Glass ball bearings have exceptional corrosion resistance, exceptional mechanical properties, and are electrically insulators.
Plastic ball bearings are created of all-plastic races and cages. These bearings are appropriate for apps that are uncovered to acids and alkalis. Because they are more affordable than glass balls, plastic ball bearings are well-known in chemical-uncovered environments. Stainless metal balls are also resistant to warmth and corrosion. But the main disadvantage of plastic ball bearings is that they are not as robust as glass balls. So, if excess weight and sound is your main issue, consider making use of plastic balls as an alternative.

Miniature

The international miniature ball bearing industry is anticipated to get to US$ 2.39 Billion by 2027, at a CAGR of 7.2%. Development in the region is attributed to technological progression and federal government initiatives. Nations around the world these kinds of as India and China are attracting FDIs and emphasizing the establishment of a worldwide production hub. This is boosting the market place for miniature ball bearings. The miniscule ball bearings are made in tiny portions and are very little.
Some makers produce miniature ball bearings in distinct supplies and types. Chrome steel is the most popular materials for miniature ball bearings due to the fact of its large load potential, reduced sound houses, and reduce price. But the expense of stainless metal miniature bearings is low, because the volume of metal utilised is small. Stainless steel miniature bearings are the smallest in dimensions. For that reason, you can select stainless steel mini ball bearings for large-velocity programs.

Angular-get in touch with

Angular-speak to ball bearings have three factors: a cage, interior ring, and balls. Angular-get in touch with ball bearings can assistance large axial and radial hundreds. Numerous design and style and production characteristics make angular-make contact with ball bearings suited for a variety of programs. Some attributes of this bearing type contain a special lubricant, diverse cage components, and diverse coatings.
The dimension of an angular-contact ball bearing is identified by the design units: outer ring width, axial load, and radial load. Relying on the variety of application, an angular-contact ball bearing could be created in double-row, triple-row, or quadruple-row configurations. Angular speak to ball bearings can be labeled in accordance to their design and style models, which variety from metric to imperial. A larger ABEC variety implies tighter tolerances. To establish the tolerance equal of a particular bearing, seek the advice of a common Angular-get in touch with ball bearing table.
Angular-contact ball bearings feature higher and reduced-shoulder configurations. They have two-dimensional races that accommodate axial and radial loads. They are available in self-retaining units with sound inner and outer rings, and ball and cage assemblies. Cages created of cast and wrought brass are the most well-known, but lightweight phenolic cages are also obtainable. The latter is a much better choice since it will not take up oil and has decrease rolling friction.

Components

When it comes to the design of a ball bearing, higher-high quality uncooked supplies are a crucial part. These components not only affect the all round quality of a ball bearing, but also affect the expense. That is why you need to spend shut focus to uncooked substance good quality. In addition to that, uncooked components ought to be examined a number of times just before the producing procedure to ensure top quality. Go through on for some data about the diverse kinds of resources used to make ball bearings.
Steel is the most widespread material for ball bearings. Most ball bearings incorporate stainless steel balls, which are remarkably corrosion-resistant. They are also resistant to saltwater and alkalis. Even so, stainless metal balls are heavier than plastic types, and they are also magnetic, which may possibly be a downside in some purposes. If you are seeking for a metal-cost-free alternative, glass balls are the way to go. They are durable, light-weight, and resistant to a wide assortment of chemical compounds.
