Bearings are accessories that are used in helping the automobiles to reduce friction. Two metals when placed in contact with each other produce a huge amount of friction. This friction totally adds to the wear and tear of both the metals in contact which also produces grinding which will start degrading the metal. Bearings in contrast, will reduce the friction by letting the two surfaces turn over each other, thereby reducing the level of friction produced. A bearing normally consists of a metal roller or bar placed against the smooth outer and inner surfaces.

Types:

There are different types of bearings manufactured to serve different scenarios and various machineries or equipments. These bearings are classified in to Cylindrical, Tapered, Spherical, Needle bearings etc. These differences in sizes and shapes are to help the bearings match the cross section and length of the machineries they fit into and also depending on the loads that act upon them. Some of the important types of bearings are discussed here.

Cylindrical Bearings:

These bearings are more commonly called as the cylindrical roller bearings and typically used to handle very high radial loads. These cylindrical bearings are made with rolling elements that are single row, two rows or multiple rows in order to meet the radial loads handling in the application’s requirement. Cylindrical bearings are available in many standard sizes, series and configurations and are used in a wide variety of industries and equipments.

Spherical bearings:

Spherical rollers or spherical bearings have roller profiles that strongly match the raceway profiles which in turn make them have a high load capacity and more robust. These bearings are mounted as pairs, well inside the housing of the bearings which are placed in opposite directions. One particular type of commonly used rolling element bearing is called the ball bearing.

Types of Ball Bearings:

Ball bearings are also called as the Conrad bearings and are typically used in applications that manage smaller loads. The Spherical ball bearings have small contact points right in between the outer race and the ball due to the bearing’s spherical shape. This will also help the ball for spinning smoothly. Since the contact point is considered to be smaller, the bearing can often become overloaded at some point, which in turn causes the bearing to get deformed.

Spherical plain bearings on the other hand are manufactured in a large variety of materials and are used in many other operating environments like heavy duty vehicles, agricultural equipments etc.
