Each of the various bearing types has benefits and drawbacks of its own. Each bearing type has unique benefits and drawbacks. There are many different bearing kinds. In this article, we'll discuss the different types of bearings available, as well as their pros and cons. We'll also go over how to choose the ideal bearing size for your requirements.

Bearing Types



There are many types of bearings, each designed to meet specific needs and applications. The top 4 bearing categories are as follows:



  • 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. Little, hardened steel balls are used in these bearings to hold the shaft in place. The balls are placed between
two circular plates called races. Another typical type of bearing uses cylindrical rollers rather than balls; these are known as roller bearings. Small, pointed needles are used by needle bearings to hold the shaft firmly in place. Thrust bearings use flat plates called races to maintain the position of a shaft.

The inner (ID) and outer (OD) diameters of a bearing define its size (OD). The bore, or the hole in the center of the bearing, is measured by a number called the ID. The measurement of the outer race is 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 load is the weight or force that the bearing will need to support. The bearing will be spinning at the specified speed. The vibration is the amount of movement that the bearing will experience.

Bearings can be purchased in a variety of places. A local bearing supplier is one choice for where to get 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 various types of bearings available on the market, each with their own advantages and disadvantages. The four most typical types of bearings are ball bearings, roller bearings, bearing housings, and bearing units. Each kind of bearing has a distinct set of qualities that make it more or less appropriate for particular purposes.

The most popular form of bearing and the one that is utilized in the most applications is the ball bearing. A set of balls that spin between inner and outer races make up these devices, which are commonly composed of steel or ceramic. For applications involving high speeds and/or weights, ball bearings are the best choice because they are relatively easy to use and long-lasting.

Ball bearings and roller bearings are comparable, although the latter are made to support larger 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 weights are present but speeds are not as high, roller bearings work better than ball bearings but are less robust.

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, pre-assembled bearings known as bearing units are ready to be installed. They typically consist 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.

In terms of rolling bearings, plain bearings, and components for linear motion, SKF is a global leader.


Ball Bearings:


The most typical bearing type is a ball bearing. In addition to a number of balls, they are constructed from two metal rings known as the inner and outer races. The bearing actually moves around on the balls. The inner race is usually attached to the shaft that the bearing is supporting. Usually, the outer race is fastened to the housing.

Roller Bearings:


Ball bearings and roller bearings are quite similar, however the latter use cylinders in place of balls. While roller bearings are able to carry greater weight than ball bearings, they are also more prone to break under heavy pressures.

Plain Bearings:



The most basic sort of bearings are plain bearings. They are made from two metal surfaces that slide against each other. To alleviate wear and friction, grease or oil can be applied to plain bearings.

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. Selecting the wrong type of bearing for your application can result in increased wear and tear, reduced performance, and even premature 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, blog and combination loads as their three main load types. Thrust loads are applied parallel to the shaft, whereas radial loads are applied perpendicular to the shaft. Together, radial and thrust loads make up combined loads.

Consider the size of the bearings to reduce your alternatives after determining the types of loads that will be placed on them. From small bearings that can sustain light weights to huge bearings that can support enormous loads, bearings come in a variety of sizes.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. 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 will require specially developed bearings for use at those speeds.And bearings that will be subject to high temperatures will need to be made from materials that can withstand high temperatures.

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


Ball bearings are the most common type of bearing and can handle both radial and thrust loads.


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, such as:

-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.The following materials are accessible for them:

-Bronze
-Babbitt
-Plastic

A bearing's inner diameter (ID), outer diameter (OD), and width all contribute to 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 width is the dimension that determines the bearing's 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.

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. It accomplishes this by using at least two races to keep the balls contained and transmit the stresses 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. German engineer Friedrich Fischer created the first industrial ball bearings in 1883.
