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 ideal bearing size for your requirements.

Bearing Types



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



  • 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 circular plates known as races. Another typical type of bearing uses cylindrical rollers rather than balls; these are known as roller bearings. Little, pointed needles are used in needle bearings to hold the shaft firmly in place. 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 ID is the measurement of the bore, or the hole in the middle of the bearing. The outer race is measured by the OD. The breadth of the bearing is measured by the width.

The load, speed, and vibration that the bearing will experience should all be taken into account when selecting a bearing. The bearing's required capacity to support a given weight or force is known as the load. The bearing will be spinning at a certain speed, which is the 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 buy bearings from a nearby source of bearings. A different 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 numerous types of bearings on the market, each with unique benefits and drawbacks. The four most typical types of bearings are ball bearings, roller bearings, bearing housings, and bearing units. Each type of bearing has its own unique set of characteristics that make it more or less suited for certain applications.

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 relatively simple and durable, making them ideal for applications where high speeds and/or loads are involved.

Roller bearings are similar to ball bearings but are designed to carry heavier loads. They are typically made from steel or brass and consist of a series of cylindrical rollers that 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.

Bearing housings are enclosures that protect bearings from contaminants and provide a way to mount them onto 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 already been put together and are ready for installation are known as bearing units. A housing, a bearing, and a seal are often included. 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 type of bearing is a ball bearing. They are constructed from a set of balls, two metal rings known as the inner and outer races, and two metal rings. 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 housing is fastened to the outside race.

Roller Bearings:


In contrast to ball bearings, which employ balls, roller bearings use cylinders. Roller bearings are more likely to break under heavy loads even if they can sustain larger loads than ball bearings.

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.

Selecting the best bearings for your application requires careful consideration of bearing types and sizes. There are many different types of bearings available on the market, and each type has its own unique set of benefits and drawbacks. If the wrong kind of bearing is chosen for your application, it may lead to greater wear and tear, decreased performance, or 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. Radial, thrust, and combined loads are the three main types of loads that bearings are intended to withstand. As opposed to thrust loads, which are applied parallel to the shaft, radial loads are applied perpendicularly. Radial and thrust loads are combined to form combined loads.

Once you have determined the kinds of loads that will be placed on the bearings, you may focus your search by taking the bearings' sizes into account. Bearings are available in a wide range of sizes, from small bearings that can support light loads to large bearings that can support heavy loads.The required bearing more info size will depend on the dimensions of the shaft and the force that will be placed on the bearings.

It is crucial to take into account the sort of environment the bearings will be working in when choosing bearings for your application. Materials that can resist rust and corrosion must be used to create bearings that will be exposed to wet or corrosive conditions. High speed operation requires that bearings be constructed 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. 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 are produced in a range of shapes and sizes, including:

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

The following types of roller bearings are available:

-Cylindrical
-Ndeep groove
-Needle
-Spherical
-Tapered

Many different applications that call for rotational or linear motion require sleeve bearings, also known as bushings.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 ID dimension defines the inner race bore size of the bearing, whereas the OD dimension determines the outer race size. 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



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. In order to contain the balls and transport the stresses via the balls, at least two races are used.
Typically, one race is attached to the rotating assembly, and the other is immobile, depending on the application. The rotating shafts of wheels were supported by ball bearings as early as in the, where they were first utilized.
Jules Suriray, a French bicycle mechanic, is credited with creating the ball bearing 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.
