Bearing Types
There are many types of bearings, each designed to meet specific needs and applications. 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. Little, hardened steel balls are used in these bearings to hold the shaft in place. The balls are positioned between two circular plates known as races. Another typical type of bearing uses cylindrical rollers rather than balls; these are known as roller bearings. Little, pointed needles are used in needle bearings to hold the shaft firmly 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 outer diameter (OD) of a bearing determine its size (OD). The bore, or the bearing's central hole, is measured by something called the ID. The measure of the outer race is called the OD. The width of the bearing is measured by this term.
The load, speed, and vibration that the bearing will experience should all be taken into account when selecting a bearing. The bearing must be able to support the load, which is the weight or force. The speed is the rate at which the bearing will be spinning. The vibration represents the amount of movement the bearing will endure.
Bearings can be purchased in a variety of locations. One option is to purchase bearings from a local bearing supplier. 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 numerous types of bearings on the market, each with unique benefits and drawbacks. 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.
The most prevalent kind of bearing is the ball bearing, which has a wide range of uses. They are typically made from steel or ceramic and consist of a series of balls that rotate between inner and outer races. 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, roller bearings are made to support greater 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.
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. 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 products for linear motion, SKF is a global leader in design, development, manufacture, and marketing.

Plain Bearings:
The most straightforward sort of bearings are plain bearings. Two metal surfaces that slide against one another are used to create them. To lessen friction and wear, 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.
Understanding the types of loads that will be placed on the bearings is the first step in choosing the best bearings for your application. Radial, thrust, and mixed loads are the three main types of loads that bearings are made to withstand. Thrust loads are applied parallel to the shaft, whereas radial loads are applied perpendicular to the shaft. The terms "radial loads" and "thrust loads" are interchangeable terms.
Once you've determined the kinds of loads that will be placed on the bearings, you may focus your search by taking the bearings' sizes into account. 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 want will depend on the diameter of the shaft and the force that will be placed on them.
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 moist or corrosive conditions.Bearings that will be operating at high speeds will need to be designed 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.
There are many different types of bearings, each designed for specific applications and operating conditions. Ball bearings, roller bearings, and sleeve bearings make up the three major kinds.
The most prevalent bearings are ball bearings, which can support both thrust and radial stresses.
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, 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
A bearing's inner diameter (ID), outer diameter (OD), and width are used to determine its size. The ID dimension defines the inner race bore size of the bearing, whereas the OD dimension determines the outer race size. The measurement that establishes the width of the bearing is its width.
- ball bearings - ID: 10 mm, OD: 30 mm, width: 9 mm
- roller bearings - ID: 20 mm, OD: 47 mm, width: 14 mm
- 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 more info lessen rotational friction. In order to contain the balls and transport the stresses via the balls, at least two races are used.
Typically, one race is attached to the rotating assembly, and the other is immobile, depending on the application. Using ball bearings to support the rotating shafts of wheels was one of the first uses for them.
French bicycle mechanic Jules Suriray is credited with developing the ball bearing in 1869. In November of that year, he submitted a patent application. German engineer Friedrich Fischer 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 used in many types of equipment, such as bicycles, fans, and roller skates. Ball bearings are available in a variety of sizes and types, depending on the application.
