Product description:

Tapered roller bearings have tapered inner and outer ring raceways between which tapered rollers are arranged. The projection lines of all the tapered surfaces meet at a common point on the bearing axis. Their design makes tapered roller bearings particularly suitable for the accommodation of combined (radial and axial) loads. The axial load carrying capacity of the bearings is largely determined by the contact angle a; The larger α , the higher the axial load carrying capacity. An indication of the angle size is given by the calculation factor e; The larger the value of e, the larger the contact angle and the greater the suitability of the bearing for carrying axial loads.

Type:

Single-row taper roller bearing,Double-row taper roller bearing,Four-row taper roller bearing,auto bearing,Machine-tool bearing,Construction bearing ,Heavy-duty bearing

Features: 
The inner and outer ring raceways and rollers of these bearings are made with a taper so that the surface planes of the raceways and roller axis meet at a point .The rollers are guided by a flange on the inner ring .Tapered roller bearings are separable, and have the following components: outer ring, inner ring and roller assembly. The non-separable inner ring and roller assembly is called the ‘cone', and the outer ring is called the ‘cup'. Internal clearances established during mounting by the axial position of the cone relative to the cup.

Applications

In many applications tapered roller bearings are used in back-to-back pairs so that axial forces can be supported equally in either direction.Pairs of tapered roller bearings are used in car and vehicle wheel bearings where they must cope simultaneously with large vertical (radial) and horizontal (axial) forces.
