9 tip to get to know bearing

There are numerous types of bearings, each with particular advantages and disadvantages. A bearing's performance is also impacted by its size. Every type of bearing has advantages and cons of its own. There are many different bearing types, and each has unique benefits and drawbacks. In this article, we'll discuss the different types of bearings available, as well as their pros and cons. Furthermore, we'll describe 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 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 tools and machines. 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. Another typical type of bearing is the roller bearing, which substitutes cylindrical rollers for balls. To hold the shaft in place, needle bearings use tiny, pointed needles. 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 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 load is the weight or force that the bearing will need to support. 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 a variety of locations. One choice is to get bearings from a nearby bearing supplier. A different choice is to buy bearings from a bearings-specific website online.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 numerous types of bearings on the market, each with unique benefits and drawbacks. The four most typical types of bearings are ball bearings, roller bearings, bearing housings, and bearing units. Each type of bearing has its own unique set of characteristics that make it more or less suited for certain applications.

The most prevalent form of bearing and its many applications are ball bearings. 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, 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.

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 are typically made from cast iron or steel and are available in a variety of sizes and shapes.

Self-contained bearings that have been pre-assembled and are prepared for installation are known as bearing units. 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.

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:


Ball bearings are the most common type of bearing. They are comprised of a number of balls, two metal rings known as the inner and outer races, and the rings. The real rolling surface of the bearing is the balls. Typically, the inner race is fastened to the shaft the bearing is supporting. 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. As opposed to thrust loads, which are applied parallel to the shaft, radial loads are applied perpendicularly. Radial and thrust loads combine to form combined loads.

Once you have identified the type of loads that will be applied to the bearings, you can narrow down your options by considering the size of the bearings. 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 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 necessitate the design of bearings that will be used at such rates.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. 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 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 are available in a variety of materials, including:

-Bronze
-Babbitt
-Plastic

A bearing's inner diameter (ID), outer diameter (OD), and width are used to determine its size. The bearing's inner race bore size is determined by the bearing's ID, while the outer race size is determined by the bearing's 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



When choosing a bearing for a particular application, it's crucial to take the ID, OD, and breadth into account.

The gap between the bearing races is maintained by balls in a ball bearing, a form of rolling-element bearing. A ball bearing's main functions are to support radial and axial loads and lessen rotational friction. It does this by containing the balls in at least two races and transmitting the loads through the balls.
In the majority of applications, one race is coupled to the rotating assembly, and the other is immobile. Using ball bearings to support the rotating shafts of wheels was one of additional informations about bearings 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 applied for a patent. Engineer Friedrich Fischer from Germany created the first industrial ball bearings in 1883.

Two surfaces can move smoothly and with less friction when they come into contact with one another thanks to bearings. Little metal balls are used in ball bearings to lower friction, hence the name "ball bearing" is a misnomer. The balls are positioned between two races, or rings, and they revolve as the inner ring does.

Several industries, including the automotive, aerospace, and industrial sectors, employ ball bearings. They are also found in many different pieces of equipment, including roller skates, fans, and bicycles.Depending on the purpose, there are many different sizes and types of ball bearings.
