Tapered roller bearings

Tapered roller bearings are generally used to sup-port combined load mainly consisting of radial load. Their cups are separable for easy assem-bling. During mounting and using, radial clear-ance and axial clearance can be adjusted and preloaded mounting can be made.

With the same center as the bearing, the spherically formed outer ring raceway can make self-alignment. Their rolling elements linearly come into contact with the raceways of in-ner ring and outer ring. The bearings can take greatly radial load, suitable for heavy machinery used in mining, metallurgical, paper-making and construction industries.
