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. In between two circular plates known as races, the balls are positioned. Roller bearings are also a common type of bearing and use cylindrical rollers instead of balls. The shaft is held in position by tiny, pointed needles in needle bearings. Thrust bearings are bearings that keep a shaft in place by using flat plates called races.

The inner (ID) and outer (OD) diameters of a bearing define its size (OD). The bore, or the hole in the center of the bearing, is measured by the ID. The outer race is measured by 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 bearing must be able to support the load, which is the weight or force. The bearing will be spinning at a certain speed, which is the speed. The vibration represents the amount of movement the bearing will endure.

Bearings can be purchased in many different locations. One choice is to get bearings from a nearby bearing supplier. Another option is to purchase bearings online from a website that specializes in bearings.Several bearings-selling websites additionally offer a web-based quote system that enables you to get a price for the bearings you require.

On the market, there are numerous bearing kinds, each with advantages and drawbacks of their own. Ball bearings, roller bearings, bearing housings, and bearing units are the four most typical types of bearings. Each type of bearing has a distinct set of qualities that make it more or less suitable for particular purposes.

Ball bearings are the most common type of bearing and are used in a wide variety of applications. They usually consist of a number of rotating balls that alternate between inner and outer races, and they are composed of steel or ceramic. Ball bearings are perfect for applications involving high speeds and/or loads since they are reasonably easy to use and long-lasting.

Although identical to ball bearings, roller bearings are made to support greater loads. They typically consist of a set of cylindrical rollers rotating between inner and outer races and are constructed 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.

It is possible to place bearings onto a shaft or other support structure using bearing housings, which are enclosures that shield them from external pollutants. Bearing housings are typically made from cast iron or steel and are available in a variety of sizes and shapes.

Self-contained bearings that have been pre-assembled and are prepared for installation are known as bearing units. Usually, a housing, a bearing, and a seal make up these devices. Bearing units are available in a variety of sizes and configurations, making them suitable for a wide range of applications.

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


Ball Bearings:


The most popular kind of bearings are ball bearings. They are made from two metal rings, called the inner and outer races, and a group of balls. The real rolling surface of the bearing is the balls. The inner race is usually attached to the shaft that the bearing is supporting. Typically, the outer race is fastened to the housing.

Roller Bearings:


Ball bearings and roller bearings are quite similar, however the latter use cylinders in place of balls. Compared to ball bearings, roller bearings can withstand larger loads, but they are also more prone to failure when subjected to heavy loads.

Plain Bearings:



The most basic sort of bearings are plain bearings. They're constructed from two sliding metal surfaces. Plain bearings can be lubricated with oil or grease to reduce friction and wear.

Bearing types and sizes are very important factors to consider when selecting the right bearings for your application. There are numerous varieties of bearings on the market, and each type has a distinct set of advantages and disadvantages.The market offers a wide variety of bearing types, and each kind 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.

Identifying the kind of loads that will be placed on the bearings is the first step in choosing the best bearings for your application. Bearings are made to sustain three different types of loads: radial, thrust, and combination. As opposed to thrust loads, which are applied parallel to the shaft, radial loads are applied perpendicularly. Radial and thrust loads combine to form combined loads.

Once you have identified the type of loads that will be applied to the bearings, you can narrow down your options by considering the size of the bearings. From small bearings that can sustain light weights to huge bearings that can support enormous loads, bearings come in a variety of sizes.The shaft's diameter and the amount of load that will be placed on the bearings will determine the size of bearings you require.

When selecting bearings for your application, it is important to consider the type of environment the bearings will be operating in. Rust- and corrosion-resistant materials must be used to create bearings that will be used in wet or corrosive conditions.Bearings that will be operating at high speeds will need to be designed for high speed operation.Furthermore, materials that can endure high temperatures must be used to create bearings that will be exposed to them.

Bearings come in a wide variety, with each type being created for a particular use or set of circumstances. Ball bearings, roller bearings, and sleeve bearings make up the three major kinds.


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


They are produced in a range of shapes and sizes, such as:

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

There are numerous varieties 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.The following materials are accessible for them:

-Bronze
-Babbitt
-Plastic

A bearing's inner diameter (ID), outer diameter (OD), and width are used to determine its size. The bearing's inner race bore size is determined by the bearing's ID, while the outer race size is determined by the bearing's OD. The width is the dimension that determines the bearing's width.



  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 ID, OD, and breadth into account.

A ball bearing is a particular 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. In order to contain the balls and transport the stresses via the balls, at least two races are used.
In the majority of applications, one race is coupled to the rotating assembly, and the other is immobile. Ball bearings were first employed to support the rotating shafts of wheels in the.
Jules Suriray, a French bicycle mechanic, is credited with developing the ball bearing in 1869. In November of that year, he applied for a patent. The first commercial ball bearings were produced by Friedrich Fischer, a German engineer, in 1883.
