We'll talk about the many types of bearings that are available in this post, along with their benefits and drawbacks. 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. The 4 main types of bearings are:



  • ball bearings

  • roller bearings

  • needle bearings

  • thrust bearings


The most prevalent type of bearing is a ball bearing, and these can be found in a variety of machines and equipment. Little, hardened steel balls are used in these bearings to hold the shaft in place. In between two circular plates known as races, the balls are positioned. Bearings that use cylindrical rollers rather than balls include roller bearings, which are also widely used. The shaft is held in position by tiny, pointed needles in needle bearings. Thrust bearings use flat plates called 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 the OD. The bearing's width is calculated using the width.

When choosing a bearing, it is important to consider the load, speed, and vibration that the bearing will be subjected to. 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 spin. The amount of movement the bearing will undergo is the vibration.

Bearings can be purchased in a variety of places. One option is to purchase bearings from a local bearing supplier. Another option is to purchase bearings online from a website that specializes in bearings.A web-based quote system is offered by some websites that sell bearings and can give you a price estimate for the bearings you require.

There are many different types of bearings on the market, and each has pros and disadvantages of their own. Ball bearings, roller bearings, bearing housings, and bearing units are the four most typical types of bearings. Each kind of bearing has a distinct set of qualities that make it more or less appropriate for particular purposes.

Ball bearings are the most common type of bearing and are used in a wide variety of applications. They are typically made from steel or ceramic and consist of a series of balls that rotate between inner and outer races. For applications involving high speeds and/or weights, ball bearings are the best choice because they are relatively easy to use and long-lasting.

Similar to ball bearings, but made to support larger loads, are roller bearings. A series of cylindrical rollers that rotate between inner and outer races make up these devices, which are commonly composed of steel or brass. Roller bearings are more effective than ball bearings but less long-lasting, making them suited for applications with higher loads but lower speeds.

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 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. In most cases, they are made up 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.

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 comprised of a number of balls, two metal rings known as the inner and outer races, and the rings. 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:


Ball bearings and roller bearings are extremely similar, however roller bearings use cylinders in place of balls. Roller bearings are more likely to break under heavy loads even if they can sustain larger loads than ball bearings.

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. If you choose the improper kind of bearing for your application, you risk performance loss, premature failure, and higher wear and strain.

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. Thrust loads are delivered parallel to the shaft, while radial loads are applied perpendicular to the shaft. Radial and thrust loads combine 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. 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 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. It is necessary to use materials that can resist rust and corrosion when creating bearings that will be used in wet or corrosive settings.High speed operation will require specially developed bearings for use at those speeds.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. Ball bearings, roller bearings, and sleeve bearings make up the three major kinds.


The most typical bearing is a ball bearing, which can support both thrust and radial stresses.


They are produced in a range of shapes and sizes, such as:

-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 inner diameter (ID), outer diameter (OD), and width of a bearing are used to determine its size. The ID is the dimension that determines the bearing's inner race bore size, while the OD is the dimension that determines the size of the bearing's outer race. The bearing's breadth is determined by the width as 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



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 type of rolling-element bearing that uses balls to maintain the separation between the bearing races. A ball bearing's main functions more info 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. An early application of the ball bearing was in the, where they were used to support the rotating shafts of wheels.
Jules Suriray, a French bicycle mechanic, is credited with developing the ball bearing in 1869. That year, in November, he submitted a patent application. Engineer Friedrich Fischer from Germany created the first industrial ball bearings in 1883.
