Taper Roller Bearing Single Row 31311, 55mm Bore
Product Introduction:
Tapered roller bearings have specially designed raceways and asymmetrical rollers. The bearings can accommodate axial loads acting in one direction and simultaneously acting radial loads. The load is transmitted between the raceways via the rollers at an angle to the bearing axis, while the flange guides the rollers.
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.
Features of Taper Roller Bearing
The roller and the raceway are in line contact or underline contact.
Large radial load, carrying capacity and friction coefficient is small.
Suitable for high speed runing equipment.
nner ring and outer ring can be separated, easy to install and remove.
