The many bearing types that are available, as well as their benefits and drawbacks, will be covered in this article. We'll also explain how to select the right size bearing for your needs.

Bearing Types



There are numerous bearing kinds, each created to satisfy particular requirements and purposes. The top 4 bearing categories are as follows:



  • ball bearings

  • roller bearings

  • needle bearings

  • thrust bearings


The most popular form of bearing, ball bearings are used in a variety of machines and devices. They are bearings that use small, hardened steel balls to keep the shaft in place. The balls are positioned between two races, which are circular plates. Another frequent type of bearing is the roller bearing, which substitutes cylindrical rollers for balls. Small, pointed needles are used by needle bearings to hold the shaft firmly in place. Thrust bearings are types of bearings that use flat plates known as races to hold a shaft in place.

The inner diameter (ID) and the outer diameter (OD) of a bearing determine its size (OD). The bore, or the hole in the center of the bearing, is measured by the ID. The measure of the outer race is called the OD. The breadth of the bearing is measured by the width.

It is crucial to take into account the load, speed, and vibration that the bearing will experience while selecting one. The load is the amount of weight or force that the bearing must withstand. The bearing will be spinning at the specified speed. The vibration is the amount of movement that the bearing will experience.

Bearings can be purchased in many different locations. One choice is to get bearings from a neighborhood bearing supplier. A different choice is to buy bearings from a bearings-specific website online.A web-based quote system is offered by some websites that sell bearings and can give you a price estimate for the bearings you require.

There are many different types of bearings on the market, and each has pros and disadvantages of their own. The four types of bearings that are most frequently used are ball bearings, roller bearings, bearing housings, and bearing units. Each type of bearing has a distinct set of qualities that make it more or less suitable for particular purposes.

The most popular form of bearing and the one that is utilized in the most applications is the ball bearing. A set of balls that spin between inner and outer races make up these devices, which are commonly composed of steel or ceramic. For applications involving high speeds and/or weights, ball bearings are the best choice because they are relatively easy to use and long-lasting.

Ball bearings and roller bearings are comparable, although the latter are made to support larger loads. A series of cylindrical rollers that rotate between inner and outer races make up these devices, which are commonly composed of steel or brass. Roller bearings are more effective than ball bearings but less long-lasting, making them suited for applications with higher loads but lower speeds.

Bearing housings are enclosing devices that shield bearings from impurities and give them a mounting point on a shaft or other support structure. Bearing housings come in a variety of sizes and shapes and are commonly composed of cast iron or steel.

Self-contained bearings that have been pre-assembled and are prepared for installation are known as bearing units. A housing, a bearing, and a seal are often included. Due to their availability in a range of sizes and configurations, bearing units can be used in a variety of applications.

In terms of rolling bearings, plain bearings, and components for linear motion, SKF is a global leader.


Ball Bearings:


The most popular type of bearing is a ball bearing. They consist of a number of balls and two metal rings known as the inner and outer races. The bearing actually moves around on the balls. Typically, the inner race is fastened to the shaft the bearing is supporting. Most frequently, the housing is fastened to the outside race.

Roller Bearings:


Ball bearings and roller bearings are extremely similar, however roller bearings use cylinders in place of balls. Roller bearings are more likely to break under heavy loads even if they can sustain larger loads than ball bearings.

Plain Bearings:



Plain bearings are the simplest type of bearing. They're constructed from two sliding metal surfaces. Plain bearings can be lubricated with oil or grease to reduce friction and click wear.

Selecting the best bearings for your application requires careful consideration of bearing types and sizes. There are numerous varieties of bearings on the market, and each type has an own set of advantages and disadvantages. If you choose the improper kind of bearing for your application, you risk performance loss, premature failure, and higher wear and strain.

Understanding the types of loads that will be placed on the bearings is the first step in choosing the best bearings for your application. Radial, thrust, and mixed loads are the three main types of loads that bearings are made to withstand. Radial loads are applied perpendicular to the shaft, while thrust loads are applied in a parallel direction. Radial and thrust loads are combined to form combined loads.

The size of the bearings can help you focus your search once you've determined the kind of loads that will be placed on them. From small bearings that can sustain light weights to huge bearings that can support enormous loads, bearings come in a variety of sizes.The size of the bearings you want will depend on the diameter of the shaft and the force that will be placed on them.

It's critical to take the operating environment into account when choosing bearings for your application. Rust- and corrosion-resistant materials must be used to create bearings that will be used in wet or corrosive conditions.High speed operation will necessitate the design of bearings that will be used at such rates.Moreover, materials that can endure high temperatures must be used in the construction of bearings that will be exposed to them.

Bearings come in a variety of forms, each of which is created for particular uses and operational circumstances. The three major categories are sleeve bearings, ball bearings, and roller bearings.


The most prevalent bearings are ball bearings, which can withstand both thrust and radial loads.


They are manufactured in a variety of sizes and designs, including:

-Angular contact
-Double row
-Four point
-Radial
-Self-aligning

There are various types of roller bearings, including:

-Cylindrical
-Ndeep groove
-Needle
-Spherical
-Tapered

Sleeve bearings, commonly referred to as bushings, are utilized in a number of applications where rotation or linear motion is necessary.They come in a range of materials, such as:

-Bronze
-Babbitt
-Plastic

The size of a bearing is measured by its inner diameter (ID), outer diameter (OD), and width. The bearing's inner race bore size is determined by the ID, but the outer race size is determined by the OD. The bearing's breadth is decided by its width, which is a dimension.



  1. ball bearings - ID: 10 mm, OD: 30 mm, width: 9 mm

  2. roller bearings - ID: 20 mm, OD: 47 mm, width: 14 mm

  3. sleeve bearings - ID: 5 mm, OD: 10 mm, width: 4 mm



When choosing a bearing for a particular application, it's crucial to take the bearing's ID, OD, and breadth into account.

A ball bearing is a specific kind of rolling-element bearing that uses balls to keep the distance between the bearing races constant. A ball bearing's main functions are to support radial and axial loads and lessen rotational friction. It achieves this by using at least two races to contain the balls and transmit the loads through the balls.
Typically, one race is attached to the rotating assembly, and the other is immobile, depending on the application. Using ball bearings to support the rotating shafts of wheels was one of the first uses for them.
Jules Suriray, a French bicycle mechanic, is credited with developing the ball bearing in 1869. That year, in November, he submitted a patent application. Engineer Friedrich Fischer from Germany created the first industrial ball bearings in 1883.
