An Over view of Deep groove ball bearing

The bearings are the most typical rolling bearings with extensive applications. The raceways in both of the rings are in arc groove form, which can carry radial and axial load in double directions. They can be applied in situations where high-rotating speed and low noise and low vibration are required.

Bearing structure

Deep groove ball bearing has simple structure, compared with other types of easy to achieve high manufacturing accuracy, so easy to become series mass production, lower manufacturing costs, the use of very common. Deep groove ball bearing except basic types, there are various kinds of structural change, such as: deep groove ball bearings with dust cover, deep groove ball bearings with a rubber sealing ring, deep groove ball bearings with snap groove, deep groove ball bearings have high load capacity of ball filling gap, double deep groove ball bearings.

Types

Basic type; With snap ring groove on the outer ring (-N); With one shield (-Z) on one side or two shields (-2Z) on both sides; With one seal (-RS) on one side or two seals (-2RS) on both sides.

Cage material

Generally use steel stamping cage or solid brass cage. When the diameter is less than 400 mm, use steel stamping cage without rear code, solid brass multipurpose holder without rear code when the diameter greater than 400 mm.

Application

The bearings can be found in  transmission, instrumentation, motors, household appliances automobiles, machine tools, motors, instruments, construction machines, railway vehicles, agricultural machines and various other special machines.
