stainless steel deep groove ball bearings S6004ZZ S6004-2RS size:20*42*12mm

stainless steel deep groove ball bearings are the most commonly used rolling bearings. Its structure is simple and easy to use. Mainly used to bear radial load, but when the radial clearance of the Bearing is increased, it has the performance of a certain Angular Contact Ball Bearing, and can bear radial and axial combined load. When the speed is high and the Thrust Ball Bearing is not suitable, it can also be used to bear pure axial load. Compared with other types of bearings with the same specification and size as deep groove ball bearings, this kind of bearings has small friction coefficient and high limit speed. But not impact resistance, not suitable for heavy load.

Stainless steel deep groove ball bearing mounted on the shaft, in the axial clearance range of the bearing, can limit the axial displacement in both directions of the shaft or housing, so it can be axially positioned in both directions. In addition, this kind of bearing also has a certain self-aligning ability. When the bearing is tilted 2 '~ 10' relative to the shell hole, it can still work normally, but it has a certain influence on the bearing life.

Stainless steel bearing materials are mainly 420, 440, 304, 316
