How many kinds of bearing?

April 11, 2017


As we know,the bearing play an important role during the manchine work..There are at least 10 types of bearing , each of which operates on different principles

Rolling bearing:also known as a rolling-element bearing, is a bearing which carries a load by placing rolling elements (such as balls or rollers) between two bearing rings called races. The relative motion of the races causes the rolling elements to roll with very little rolling resistance and with little sliding.

Angular contact bearing:It is the nominal contact angel of the bearing which is between ball and ring larger than 0 degree,but less than 90 degree.

Spherical roller bearing:Spherical roller bearings have two rows of rollers, a common sphered outer ring raceway and two inner ring raceways inclined at an angle to the bearing axis.Mainly for simple shell use.

Linear motion bearing:it is a beating designed that the two rollers have relatively linear motion in the rolling direction

Ball bearing:The rolling element is ball.

Deep groove ball bearing: the race dimensions are close to the dimensions of the balls that run in it. Deep-groove bearings can support higher loads

Thrust ball bearings :a particular type of rotary bearing. Like other bearings they permit rotation between parts, but they are designed to support a predominately axial

Roller bearing:The rolling element of the bearing is roller.

Cylindrical Roller Bearings: are designed to carry heavy radial loads. These bearings are made with a single row, two rows, or multi-rows of rolling elements to meet an application’s radial load requirement

Needle bearing: is a special type of roller bearing which uses long, thin cylindrical rollers resembling needles. Ordinary roller bearings’ rollers are only slightly longer than their diameter, but needle bearings typically have rollers that are at least four times longer than their diameter. Like all bearings, they are used to reduce the friction of a rotating surface.

Tapered roller bearing: are rolling element bearings that can support axial forces (i.e., they are good thrust bearings) as well as radial forces.

Spherical roller bearings is a rolling-element bearing that permits rotation with low friction, and permits angular misalignment. Typically these bearings support a rotating shaft in the [bore] of the inner ring that may be misaligned in respect to the outer ring
