Taper Roller Bearings

Tata Steel Limited offers Taper Roller Bearings. These specially designed Taper Roller bearings from Tata Bearings are built to take large axial forces and sustain large radial forces. In these separable roller bearings mounted in pairs with rolling elements and raceways tapered, the four basic components are the cone, cup, tapered rollers and cage. The cone, cage and tapered rollers together form the inner ring assembly, which is separable from the outer ring. To prevent concentrating of stress at the roller’s edges, the line contact between roller and raceway is modified by Tata Bearings by crowing both rollers and raceways. This range of Tata Bearings is so designed that the extensions of raceway and roller, converge at a point on the axis of rotation. The tapered configuration facilitates the rolling motion of roller on raceway, and generates a ‘seating force’, pushing the roller against the large rib of the inner ring. This prevents the rollers from skewing off-apex, thereby always keeping them positively aligned and in contact with the inner ring rib. These bearings can not only carry a combination of radial and thrust loads, the long-line contact between rollers and races enables them to carry high loads. Depending on the magnitude of the load to be carried, the contact angle of the bearings may be narrow or wide. Taper Roller Bearings from Tata Bearings are being increasingly used in light, medium & heavy commercial vehicles, tractors, passenger cars – in the gear box, bevel pinion, front and rear wheels, water pump, etc.
