Major Types Of Bearing Used In Machines And Their Functions

The use of bearings is to reduce the friction between two parts in any moving parts in a factory or manufacturing unit. The use of a particular bearing type depends on the type machine and whether the machine is used in rotational movement or linear movement.

The shape of a bearing is like a wheel. When a bearing is used, it allows the devices to roll over it, thus reducing the friction between the objects that is rolled over it and the surface of the bearings. The use of a bearing increases the speed as the friction is reduced. The improved speed increases the efficiency and performance of a machine.

The ball bearing is one of the common types of bearings. These bearings are used to handle both thrust and radial type of loads and are used only where the small weight is involved. They cannot handle the increase in weight. The ball bearing NTN Bearing dealer in Delhi come for wide range of applications, such as in roller blades and hard drives, but they are liable to get deformed if weight is increased.

Roller bearings are made to handle heavy weight. The surface of the roller allows the weight to get distributed over the large areas. The roller structure of the roller bearing means that the bearing can handle radial load not the thrusts. For small spaces, the needle bearings with small diameter cylinder are used. The other bearings such as ball thrust bearings and thrust bearings are used for the particular loads, which is in their names.

Besides these bearings, there are specialized types of bearings NTN Bearing Importer in Delhi which are made for the specific purposes. The example of these bearings are magnetic bearings and giant roller bearings. The magnetic bearings are found in the high- speed applications, where the moving parts are not involved and giant roller bearings are used to lift the heavy load in manufacturing units.

The function of the bearing is basically very simple, they have smooth surface balls in both external and internal sides, this smooth surface allows them to move objects easily. The entire weight of the moving objects is on the balls. It is the force of the weight that moves the balls and the bearings. however, not all weights put force on the balls. Each bearing is made to handle either thrust or radial weight. Some can take both radial and thrust weight.
