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. Internal clearance is established during mounting by the axial position of the cone relative to the cup.

Metric tapered roller bearings follow the designation system defined by ISO 355.

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 (radial) and horizontal (axial) 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.

Taper roller bearing clearance:

Tapered roller bearings according to the row number of rollers,are defined as single row,double rows tapered roller bearings clearance should be adjusted when they are mounted.

For double rows and four rows tapered roller bearings,the clearance can be provided when assembling them according to national standards,customers don't need to adjust it.
