Tapered Roller Bearings

JG4A9075.JPG

Tapered roller bearings are bearings that can take large axial forces (i.e., they are good thrust bearings) as well as being able to sustain large radial forces.
The inner and outer ring raceways are segments of cones and the rollers are also made with a taper so that the conical surfaces of the raceways and the roller axes if projected, would all meet at a common point on the main axis of the bearing.
The rollers are guided by a flange on the inner ring. This stops the rollers from sliding out at high speed due to their momentum.
The larger the half angles of these cones the larger the axial force that the bearing can sustain.
Tapered roller bearings are separable and have the following components: outer ring, inner ring, and roller assembly (containing the rollers and a cage). The non-separable inner ring and roller assembly is called the cone, and the outer ring is called the cup.
