02:26 00:34 SELECTION OF GOOD BEARING STEEL QUALITY Long use time, avoid repeated disassembly and maintenance trouble.
00:33 Deep groovd ball bearings mainly bear radial load as well as axial load. With low friction coefficient, high limiting speed,
00:31 Low friction coefficient faster rotational speed, lower sound, not easy to burn.
00:34 Using excellent high-purity bearing steel, the bearing life is up to about 80%.
00:29 Their rolling elements linearly come into contact with the raceways of inner ring and outer ring.
00:31 With the same center as the bearing, the spherically formed outer ring raceway can make self-alignment.
00:32 The bearings can take greatly radial load, suitable for heavy machinery used in mining, metallurgical, paper - making and instructing, etc.
