Taper Roller Bearings
Tapered roller bearings consist of four interdependent components: the inner ring; the outer ring; the rolling elements; and the roller retainer. The taper angles allow the bearing to handle a combination of radial and thrust loads.
Tapered roller bearing are widely used in car: front-wheel, rear wheel, transmission, differential pinion shaft. Machine tool spindles, construction machinery, largescale agricultural machinery, railway vehicles, gear reduction, the rolling mill roll neck and deceleration devices.
Equipment, instrument, building machinery, rolling stock agricultural machinery and various specialized machineries.
Types of tapered roller bearings
(1). Single Row Tapered Roller Bearing
(2). Double Row Tapered Roller Bearing
(3). Four Row Tapered Roller Bearings
