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, each created to satisfy particular requirements and purposes. 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. These are bearings that hold the shaft in place using tiny, hardened steel balls. Between two circular plates known as races are the balls. Another frequent type of bearing is the roller bearing, which substitutes cylindrical rollers for balls. Needle bearings are bearings that use small, sharp needles to keep the shaft in place. With the help of flat plates known as races, thrust bearings hold a shaft firmly in place.

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

It's crucial to take into account the load, speed, and vibration that the bearing will experience while selecting one. The bearing's required capacity to support a given weight or force is known as the load. The speed is the rate at which the bearing will be spinning. The amount of movement the bearing will undergo is the vibration.

Bearings can be purchased in numerous locations. One choice is to buy bearings from a nearby source of bearings. 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. Ball bearings, roller bearings, bearing housings, and bearing units are the four most typical types of bearings. Each type of bearing has its own unique set of characteristics that make it more or less suited for certain applications.

Ball bearings are the most common type of bearing and are used in a wide variety of applications. They usually consist of a set of balls that spin between inner and outer races and are constructed of steel or ceramic. Ball bearings are very easy to use and long-lasting, which makes them perfect for applications involving high speeds and/or loads.

Similar 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. In applications where heavier loads are involved but speeds are not as high, roller bearings are more effective than ball bearings but are less long-lasting.

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. 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. In most cases, they are made up of a housing, a bearing, and a seal. Because they come in a number of sizes and configurations, bearing units can be used in a wide range of applications.

Rolling bearings, plain bearings, and components for linear motion are all created, developed, produced, and marketed by SKF, a global leader in these industries.


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 balls are what the bearing actually rolls on. 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:


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. Their construction consists of two sliding metal surfaces. To lessen wear and friction, plain bearings can be greased with oil or grease.

When choosing the best bearings for your application, bearing types and sizes are crucial considerations. 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. The improper kind of bearing for your application can lead to increased wear and tear, decreased performance, and even early failure.

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 support radial, thrust, and combination loads as their three main load types. Radial loads are applied perpendicular to the shaft, while thrust loads are applied in a parallel direction. Combined loads are a combination of radial and thrust 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. From small bearings that can sustain light weights to huge bearings that can support enormous click loads, bearings come in a variety of sizes.The required bearing 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. Rust- and corrosion-resistant materials must be used to create bearings that will be used in wet 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 are produced in a range of shapes and sizes, including:

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

There are various types 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.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, the ID, OD, and width of the bearing are all crucial considerations.

A ball bearing is a particular kind of rolling element bearing that uses balls to keep the distance between the bearing races constant. The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. 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. 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 same year, he submitted a patent. Engineer Friedrich Fischer from Germany created the first industrial ball bearings in 1883.
