he difference between the high speed bearing and the ordinary bearing
The difference between the high speed bearing and the ordinary bearing is that:
High speed bearings have higher accuracy and lower surface roughness than vulgar bearings. The intuitive difference is that the high speed bearing is smoother than the surface of the vulgar bearing, and the clearance of the high speed bearing is smaller if the outer ring and the inner ring are swaying.
General high speed bearings refer to bearings with speeds up to 60 meters per second. High speed, medium speed and low speed of bearings are not determined by speed, but by linear speed. Small bearings can not be counted tens of thousands of high-speed bearings, hundreds of large bearings even high speed bearings. In sliding bearings, hydrostatic bearings, hydrodynamic bearings, aerostatic bearings, and gas dynamic bearings are all suitable for high-speed rotation.
