The many bearing types that are available, as well as their benefits and drawbacks, will be covered in this article. We'll also go over how to choose the ideal bearing size for your requirements.

Bearing Types



There are numerous bearing kinds, and each is made to serve a certain purpose. There are 4 primary categories of bearings:



  • ball bearings

  • roller bearings

  • needle bearings

  • thrust bearings


Ball bearings are the most common type of bearing and can be found in a wide range of machinery and equipment. Little, hardened steel balls are used in these bearings to hold the shaft in place. The balls are placed between
two circular plates called races. Another typical type of bearing uses cylindrical rollers rather than balls; these are known as roller bearings. Small, pointed needles are used by needle bearings to hold the shaft firmly in place. Thrust bearings use flat plates called races to hold a shaft in place.

The inner diameter (ID) and outer diameter (OD) of a bearing determine its size (OD). The diameter (ID) of the bore, or the hole in the center of the bearing, is its measurement. The measurement 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 bearing must be able to support the load, which is the weight or force. The bearing will be spinning at the specified speed. The amount of movement the bearing will undergo is the vibration.

Bearings can be purchased in a variety of places. One choice is to get bearings from a neighborhood bearing supplier. Another choice is to buy bearings from a bearings-specific website online.Some websites that sell bearings also offer a web-based quoting system that can provide you with a quote for the bearings that you need.

There are various types of bearings available on the market, each with their own advantages and disadvantages. The four types of bearings that are most frequently used are ball bearings, roller bearings, bearing housings, and bearing units. Every type of bearing has a special set of qualities that make it more or less suitable for particular applications.

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. 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 efficient than ball bearings but are not as durable, making them suitable for applications where higher loads are involved but speeds are not as high.

Bearing housings are enclosures that shield bearings from outside elements and give them a mounting point on a shaft or other support structure. There are many different sizes and types of bearing housings, which are commonly composed of steel or cast iron.

Self-contained bearings that have already been put together and are ready for installation are known as bearing units. They typically consist of a housing, a bearing, and a seal. Since they come in a number of sizes and configurations, bearing units can be used in 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 prevalent kind of bearings are ball bearings. They are constructed from a set of balls, two metal rings known as the inner and outer races, and two metal rings. The bearing really rolls on the balls. Typically, the inner race is fastened to the shaft that the bearing is supporting. Typically, the outer race is fastened to the housing.

Roller Bearings:


Comparable to ball bearings in many ways, roller bearings use cylinders as opposed to balls. Roller bearings can support higher loads than ball bearings, but they are also more likely to fail under high 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.

When choosing the best bearings for your application, bearing types and sizes are crucial considerations. There are many different types of bearings available on the market, and each type has its own unique set of benefits and drawbacks. The improper kind of bearing for your application can lead to increased wear and tear, decreased performance, and even early failure.

The first step in selecting the right bearings for your application is to identify the type of loads that will be applied to the bearings. Radial, thrust, and combined loads are the three main types of loads that bearings are intended to withstand. Whereas thrust loads are provided in a parallel direction, radial loads are applied perpendicular to the shaft. The terms "radial loads" and "thrust loads" are interchangeable terms.

Consider the size of the bearings to reduce your alternatives after determining the types of loads that will be placed on them. There are many different sizes of bearings, ranging from tiny bearings that can sustain light loads to big bearings that can support enormous loads.The size of the bearings you require will depend on the size of the shaft and the amount of load that will be placed on the bearings.

It's crucial to take the operating environment into account when choosing bearings for your application. Materials that can resist rust and corrosion must be used to create bearings that will be exposed to moist 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.

There are numerous varieties of bearings, each of which is created for a particular use and set of circumstances. Ball bearings, roller bearings, and sleeve bearings make up the three primary kinds.


Ball bearings are the most common type of bearing and can handle both radial and thrust loads.


They come in many different shapes and sizes, including:

-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, also known as bushings, are used in a wide variety of applications requiring rotation or linear motion.The following materials are accessible for them:

-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 measurement that establishes the width of the bearing is its 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



The ID, OD, and width of a bearing are all important factors to consider when selecting a bearing for a specific application.

A ball bearing is a particular kind of rolling additional informations about bearings 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. At least two races are used to hold the balls and transport the weights through the balls in order to do this.
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.
The invention of the ball bearing is attributed to Jules Suriray, a French bicycle mechanic, in 1869. In November of that year, he applied for a patent. German engineer Friedrich Fischer created the initial ball bearings for commercial use in 1883.
