Introduction to deep groove ball bearings

Deep groove ball bearings are suitable for high or even extremely high speed operation, and are very durable, without frequent maintenance. This kind of bearing has small friction coefficient, high limit speed, diverse size range and form. It is used in precision instrument, low noise motor, automobile, motorcycle and general machinery and other industries. It is the most widely used kind of bearing in the machinery industry. Mainly bear radial load, can also bear a certain amount of axial load.

Deep groove ball bearings are the most common type of rolling bearings. The basic type of deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls and a set of cages. Deep groove ball bearing types have single row and double row, deep groove ball structure is also divided into sealed and open structure, open type refers to the bearing without sealing structure, sealed deep groove ball is divided into dust seal and oil seal. Dustproof sealing cover material for steel plate stamping, only play a simple to prevent dust into the bearing raceway. The oil-proof type is contact oil seal, which can effectively prevent the grease in the bearing from spilling.

Single row deep groove ball bearing type code is 6, double row deep groove ball bearing code is 4. Its structure is simple, easy to use, is the production of the most common, the most widely used kind of bearings.
