Koyo STD 3065 30x65x21.65mm Taper Roller Bearing STD3065 

Quick Detail

Description

Taper roller bearings contain four main components: the inner rings,the outer ring(or cup),the tapered rolling elements,and the roller retainer(or cage).These bearings are specially engineered with tapered angles to accommodate both radial loads and thrust in housings and on rotating shaft assemblies.The sheerer the angel of the cup taper, the higher the thrust load tolerance of the taper roller bearing.

Tapered roller bearings are mainly used to bear the radial load-based radial and axial joint load, generally should not bear the axial load alone. This type of bearing is designed so that the inner ring raceway surface, the outer ring raceway surface and the roller rolling surface of the conical surface of the vertex intersect the bearing center line.
