what are tapered rollers?the tapered rollers meaning all the body are tapered, but the ends finish are flat.they as rolling elements used to tapered rollers braring.
tapered roller bearings are bearings that can take large axial forces as well as being able to sustain large radial forces.
applications for tapered roller bearings are commonly used for moderate speed, heavy duty applications where durability is required. common real world applications are in agriculture, construction and mining equipment, axle systems, gear box, engine motors and reducers.
we supply high quality manufactured tapered rollers, precision cone ends of cylindrical rollers, miniature needle rollers with cuspidal ends producers in hardened chrome alloy steel or SAE 521000,100Cr6, in both inch and metric sizes. the tapered rollers are available in pull and plain design. We also custom manufacture special loose tapered rollers to your specification, and will be pleased to offer our quotation upon receipt of your detailed requirements.
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 and horizontal forces.
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 clearance is established during mounting by the axial position of the cone relative to the cup.
