tapered roller bearings

Tapered roller bearings are rolling element bearings that can support axial forces (i.e., suitable thrust bearings) and radial forces.The inner and outer ring raceways are segments of cones, and the rollers are tapered so that the conical surfaces of the raceways, and the roller axes if projected, would all meet at a common point on the central axis of the bearing. This geometry makes the motion of the cones remain coaxial, with no sliding motion between the raceways and the outside diameter of the rollers.

Advantages

• Minimize friction causing reduced heat being generated

• It can easily support directional loading

• The ability to support heavy thrust and radial loads beats spherical, cylindrical, or needle roller bearings.

• Most can support pure radial, pure axial, or any combination without modification.

• Have a high load capacity

• Proper rolling motion, meaning less skidding or sliding when unloading

• Minimal load requirements
