Each type of bearing has benefits and drawbacks of its own. There are many different bearing types, and each has unique benefits and drawbacks. 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 pick the appropriate size bearing for your requirements.

Bearing Types



There are many different kinds of bearings, each created to address particular demands and purposes. The four primary categories of bearings are:



  • ball bearings

  • roller bearings

  • needle bearings

  • thrust bearings


The most prevalent type of bearing is a ball bearing, which is used in a variety of machines and apparatus. They are bearings that use small, hardened steel balls to keep the shaft in place. The balls are placed between
two circular plates called races. Bearings that use cylindrical rollers rather than balls include roller bearings, which are also widely used. Little, pointed needles are used in 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.

Inner diameter (ID) and outer diameter (OD) together determine a bearing's size (OD). The ID is the measurement of the bore, or the hole in the middle of the bearing. The measurement of the outer race is called the OD. The width is the measurement of the width of the bearing.

The load, speed, and vibration that the bearing will experience should all be taken into account when selecting a bearing. 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 amount of movement the bearing will undergo is the vibration.

Bearings can be purchased in numerous locations. One choice is to get bearings from a neighborhood bearing supplier. Your purchasing of bearings from a bearings-specific website online is an additional choice.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 most typical bearing varieties 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 prevalent kind of bearing is the ball bearing, which has a wide range of uses. A set of balls that spin between inner and outer races make up these devices, which are commonly composed of steel or ceramic. Ball bearings are very easy to use and long-lasting, making them perfect for applications involving high speeds and/or loads.

Ball bearings and roller bearings are comparable, although the latter are made to support larger loads. Usually made of steel or brass, they are composed of a number of cylindrical rollers that alternately rotate between inner and outer races. 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.

In addition to providing a means of mounting bearings onto a shaft or other support structure, bearing housings 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 built and are prepared for installation are known as bearing units. Typically, they are made up of a housing, a bearing, and a seal. A wide range of applications can be accommodated by the availability of bearing units in a variety of sizes and configurations.

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. In actuality, the bearing rolls 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:


Roller bearings are very similar to ball bearings, but instead of balls, they use cylinders. 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. Two metal surfaces that slide blog against one another are used to create them. To lessen friction and wear, plain bearings can be greased with oil or grease.

When choosing the correct bearings for your application, bearing types and sizes are crucial considerations. There are numerous varieties of bearings on the market, and each type has an own set of advantages and disadvantages. The improper kind of bearing for your application can lead to increased wear and tear, decreased performance, and even early failure.

Identifying the kinds 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. 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. Small bearings that can handle modest loads are readily accessible, as are huge bearings that can support heavy loads.The shaft's diameter and the amount of load that will be placed on the bearings will determine the size of bearings you require.

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 require specially developed bearings for use at those speeds.And materials that can endure high temperatures must be used to create bearings that will be exposed to those temperatures.

Bearings come in a wide variety, with each type being created for a particular use or set of circumstances. The three main categories are ball bearings, roller bearings, and sleeve bearings.


The most prevalent bearings are ball bearings, which can support both thrust and radial stresses.


They come in a range of 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, commonly referred to as bushings, are employed in a number of applications that call for rotation or linear motion.They come in a range of materials, including:

-Bronze
-Babbitt
-Plastic

The inner diameter (ID), outer diameter (OD), and width of a bearing are used to determine its size. 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.

The gap between the bearing races is maintained by balls in a ball bearing, a form of rolling-element bearing. 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.
One race is typically stationary and the other is joined to the rotating assembly in most applications. Using ball bearings to support the rotating shafts of wheels was one of the first uses for them.
The invention of the ball bearing is attributed to Jules Suriray, a French bicycle mechanic, in 1869. That year, in November, he submitted a patent application. The first commercial ball bearings were produced by Friedrich Fischer, a German engineer, in 1883.
