Roller Bearings

Different types of roller bearings are cylindrical, spherical, tapered, and needle. They have higher load capacities than ball bearings and moderate-speed applications. However, except for cylindrical bearings, they have lower speed capabilities. Roller bearings are used in rotary applications to replace sliding movement with low friction, rolling.

Tapered roller bearings consist of four basic components including the inner ring, the outer ring, tapered rollers, and cage. Under normal operating conditions, the cage spaces and retains the rollers on the inner ring or the cone and rest of the elements carry the load. The cone, rollers and cage are referred to as the cone assembly. The cup (outer ring) is usually separable from the cone assembly. They come in a variety of configurations like single-row, two-row, four-row and thrust bearing assemblies. Materials used for roller bearings are either alloy or low carbon steels. The carbon and alloys are added to ensure a proper combination of hard fatigue resistant case and a tough ductile core.

Tapered roller bearings have the inherent advantage of being adjustable and, they can be set to approach optimum performance in almost any application. Automated roller bearing setting techniques offer many advantages like reduced setting time, assembly cost, and and reliable setting..

To select the right roller bearing, one must determine the desired bearing life and a sufficient basic dynamic load rating to meet that life requirement. Roller bearings are used in power generation, wind turbines, gear drives, rolling mills. Single-row tapered roller bearings are used in machine tool spindles, gear reduction units etc.
