Each of the various bearing types has benefits and drawbacks of its own. There are many different bearing types, each with unique benefits and drawbacks. In this article, we'll discuss the different types of bearings available, as well as their pros and cons. We'll also explain how to select the right size bearing for your needs.

Bearing Types



There are numerous bearing kinds, each created to satisfy particular requirements and purposes. The four primary categories of bearings are:



  • 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. The shaft is held in position by these bearings, which use tiny, hardened steel balls. Between two circular plates known as races are the balls. Bearings that use cylindrical rollers rather than balls include roller bearings, which are also widely used. Needle bearings are bearings that use small, sharp needles to keep the shaft in place. Thrust bearings are types of bearings that use flat plates known as races to hold a shaft in place.

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

It's crucial to take into account the load, speed, and vibration that the bearing will experience while selecting one. The load is the amount of weight or force that the bearing must withstand. 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. 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. Ball bearings, roller bearings, bearing housings, and bearing units are the four most typical types of bearings. Every type of bearing has a special set of qualities that make it more or less suitable for particular applications.

The most popular form of bearing and the one that is utilized in the most applications is the ball bearing. They typically consist of a set of balls that spin between inner and outer races and are constructed 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.

Similar to ball bearings, but made to support larger loads, are roller bearings. Usually made of steel or brass, they are composed of a number of cylindrical rollers that alternately 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 enclosing devices that shield bearings from impurities and give them a mounting point on a shaft or other support structure. A range of sizes and shapes are available for bearing housings, which are commonly composed of cast iron or steel.

Bearing units are self-contained bearings that are pre-assembled and ready to be installed. Usually, a housing, a bearing, and a seal make up these devices. Due to their availability in a range of sizes and configurations, bearing units can be used in a variety 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:


Roller bearings are very similar to ball bearings, but instead of balls, they use cylinders. Compared to ball bearings, roller bearings can withstand larger loads, but they are also more prone to failure when subjected to heavy loads.

Plain Bearings:



The simplest sort of bearings are plain bearings. Two metal surfaces that slide against one another are used to create them. 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 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. There are three primary types of loads that bearings are designed to support: radial, thrust, and combined. Thrust loads are applied parallel to the shaft, whereas radial loads are applied perpendicular to the shaft. Radial and thrust loads combine to form 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 size of the bearings you want will depend on the diameter of the shaft and the force that will be placed on them.

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 moist or corrosive conditions.High speed operation will require that bearings be developed for high speed operation.Moreover, materials that can endure high temperatures must be used to create bearings that will be exposed to those temperatures.

Bearings come in a variety of forms, each of which is created for particular uses and operational circumstances. The three major categories are sleeve bearings, ball bearings, and roller bearings.


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


They are manufactured in a variety of sizes and designs, including:

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

There are various types of roller bearings, including:

-Cylindrical
-Ndeep groove
-Needle
-Spherical
-Tapered

Bushings, also referred to as sleeve bearings, are utilized in a number of applications that call for rotation or linear motion.They are available in a variety of materials, including:

-Bronze
-Babbitt
-Plastic

The size of a bearing is measured by its inner diameter (ID), outer diameter (OD), and width. 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 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



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 bearing races apart. 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.
In the majority of applications, one race is coupled to the rotating assembly, and the other is immobile. 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 creating the ball bearing in 1869. That year, in November, he submitted a patent application. The first commercial ball bearings were produced by Friedrich Fischer, a German engineer, in 1883.
