Bearing Depot & Supply has a large stock of tapered roller bearings consisting of four interdependent components: the cone, or inner ring; the cup, or outer ring; the tapered rollers, or rolling elements. With inch and metric sizes, the axial load carrying capacity of tapered roller bearings increases with increasing contact angle. The roller parts rotate within the cone and the cup sits on top allowing the cone to rotate independently of the cup or outer ring. These industrial-strength machine bearings are made of pressed steel and run fluidly to reduce noise and friction within any given application when installed properly.
