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


The most prevalent type of bearing is a ball bearing, which is used in a variety of tools and machines. Little, hardened steel balls are used in these bearings to hold the shaft in place. The balls are positioned between two circular plates known as races. Another frequent type of bearing is the roller bearing, which substitutes cylindrical rollers for balls. Little, pointed needles are used in needle bearings to hold the shaft firmly in place. Thrust bearings use flat plates called races to hold a shaft in place.

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

Bearings can be purchased in a variety of 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.You can get a quote for the bearings you need from several bearing-selling companies using their web-based quoting system.

There are many different types of bearings on the market, and each has benefits and drawbacks of their own. The four most typical bearing varieties are ball bearings, roller bearings, bearing housings, and bearing units. Every kind of bearing has a distinct set of qualities that make it more or less appropriate for particular applications.

The most prevalent kind of bearing is the ball bearing, which has a wide range of uses. 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.

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.

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. A range of sizes and shapes are available for bearing housings, which are commonly composed of cast iron or steel.

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. 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 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. 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. Although roller bearings are able to carry greater weight than ball bearings, they are also more prone to break under heavy pressures.

Plain Bearings:



The simplest kind of bearings are plain bearings. Two metal surfaces that slide against one another are used to create them. To lessen wear and friction, plain bearings can be greased with oil or grease.

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. Selecting the wrong type of bearing for your application can result in increased wear and tear, reduced performance, and even premature failure.

The first step in choosing the ideal bearings for your application is to determine the kinds of loads that will be placed on the bearings. Bearings are made to support radial, thrust, and combination loads as their three main load types. As opposed to thrust loads, which are applied parallel to the shaft, radial loads are applied perpendicularly. 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 small bearings that can sustain low loads to huge 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.


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

Roller bearings are available in several different types, 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 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 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



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. At least two races are used to hold the balls and transport the weights through the balls in order to do this.
In most applications, one race is stationary and the other is attached to the rotating assembly. The rotating shafts of wheels were supported by ball bearings in an early application of this technology in the.
Jules Suriray, a French bicycle mechanic, is credited with creating the ball bearing in 1869. He filed a patent in November of that year. German engineer Friedrich Fischer created the first industrial ball bearings in 1883.
