Bearing

Description/ Specification of Bearing

Bearings are machinery parts used for supporting rotating machine elements radially, axially or both. These elements transfer the mechanical loads from the rotating shafts to the stationary structure supporting it such as bearing pedestal. Bearings reduce friction during the rotation. The two basic types are plain bearings and anti friction bearings. Plain bearings are having larger cylindrical surfaces supporting the shaft and have sliding contact with shaft. Due to larger area, the friction is more and requires more lubrication. Antifriction bearings, such as ball or roller bearings on the other hand are having rolling element with lesser contact area and hence less friction. Roller bearings are capable of taking more load than ball bearings and used in heavy duty applications. There are various types of roller bearings like spherical roller bearings(SRB), Cylindrical Roller Bearings(CRB), tapered roller bearings, needle roller bearings etc. for different applications. In antifriction bearings, the rotating elements roll between the inner race, fitted on the shaft and the outer race which is placed in the bearing housing. The rotating elements like balls are separated among themselves by an element called cage. Deep grove ball bearings are the most common type used for smaller devices like motors, pumps, and fans of smaller size. Lubricant used for smaller size bearing is grease, whereas for heavy duty applications oil bath or forced oil lubrication with oil pump, cooler and filter system is used. Some bearings have permanent grease lubrication and sealed for life. Bearings, being wear parts have definite life and are to be replaced at regular intervals.Find bearing manufacturers, bearing dealers, bearing exporters from various places in India who are Dealers in Ball bearings, Dealers in Roller bearings, Dealer in Thrust bearings and other types of bearings, with their Contact details, Product range, Business descriptions etc.
