Bearing clearance

Bearing ( 轴承) Clearance of bearing clearance refers to the inner ring and outer ring of a fixed, make another move when the offset. Thin wall bearings manufacturer of angular contact ball bearings can match the optimal number of balls and the contact Angle of 30 °. They support radial load is higher than contact bearing deep groove ball bearings or four o 'clock, and can support comes from the same direction of axial load. In view of the special demand, bearing the use of clean environment for bearing is very important. Such as cross section thin-walled bearing ring rotation surface and rough surface precision of the rolling element is about 1/10 microns, this smooth surface of the ball if polluted, its influence is very serious. Bearing work ( 旋转) While you work, 工作) The size of the clearance of bearing rolling, life ( 一生) , vibration, 振动) And noise ( Db ( dB) ) , performance (such as temperature 兴能) A great influence. Now press the bearing structure, 结构) List the clearance for table without preload.
