17 knowledge to know types bearing

There are various types of bearings, each with unique benefits and drawbacks. The performance of a bearing is also impacted by its size. The different bearing types each have their own advantages and disadvantages. There are many different bearing types, each with unique benefits and drawbacks. The many bearing types that are available, as well as their benefits and drawbacks, will be covered in this article. 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 top 4 bearing categories are as follows:



  • 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 machines and apparatus. These are bearings that hold the shaft in position using tiny, hardened steel balls. Between two circular plates known as races are the balls. Another typical 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. With the help of flat plates known as races, thrust bearings hold a shaft firmly 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 outer race is measured by the OD. The breadth of the bearing is measured by the width.

The load, speed, and vibration that the bearing will experience should all be taken into account when selecting a bearing. 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 vibration is the amount of movement that the bearing will experience.

Bearings can be purchased in many different locations. One choice is to get bearings from a neighborhood bearing supplier. A different choice is to buy bearings from a bearings-specific website online.You can get a quote for the bearings you need from some bearings-selling websites using their web-based quoting system.

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 very easy to use and long-lasting, making them perfect for applications involving high speeds and/or loads.

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.

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 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.

In terms of rolling bearings, plain bearings, and products for linear motion, SKF is a global leader in design, development, manufacture, and marketing.


Ball Bearings:


Ball bearings are the most common type of bearing. In addition to a number of balls, they are constructed from two metal rings known as the inner and outer races. The balls are what the bearing actually rolls on. The shaft that the bearing is supporting normally has the inner race linked to it. Usually, the outer race is fastened to the housing.

Roller Bearings:


Ball bearings and roller bearings are extremely similar, however roller bearings 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:



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. Bearings come in a wide variety of forms, and each type has a distinct set of advantages and disadvantages that can be found on the market. If you choose the improper kind of bearing for your application, you risk performance loss, premature failure, and higher wear and strain.

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 sustain three different types of loads: radial, thrust, and combination. Thrust loads are applied parallel to the shaft, whereas radial loads are applied perpendicular to click the shaft. Radial and thrust loads are combined 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 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 require that bearings be developed for high speed operation.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 main categories 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 many different 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

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

-Bronze
-Babbitt
-Plastic

A bearing's inner diameter (ID), outer diameter (OD), and width all contribute to its size. Whereas the OD determines the size of the bearing's outer race, the ID is the parameter that determines the bore size of the bearing's inner race. The bearing's breadth is determined by the 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 type of rolling-element bearing that uses balls to maintain the separation between the bearing races. A ball bearing's main functions 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. Using ball bearings to support the rotating shafts of wheels was one of the first uses for them.
In 1869, a French bicycle mechanic named Jules Suriray is credited with developing the ball bearing. In November of that year, he submitted a patent application. German engineer Friedrich Fischer created the first industrial ball bearings in 1883.
