USMA Inch roller bearing 24780/20 24780/21 tapered roller bearing 24780/20

Inch taper/tapered roller bearings belong to separable bearing, as the outer ring, also called cup, is separable and easy for assembly. Both the inner ring(cone) and the outer ring(cup) have tapered raceways which allow the tapered rollers run smoothly within the rings.

The structure and assembly dimensional accuracy and rotation accuracy of inch tapered roller bearings are different from those of metric bearings. It is mostly used for imported machinery or industries with special needs.

The tapered roller bearings are widely used in industry, machinery, automobile, metallurgy, mining, railway and other fields. Its main applications include the following aspects:
1. Automobiles and vehicles
2. Machine tools and industrial equipment
3. Agricultural and gardening machinery
4. Railway and aerospace
5. Mining and construction engineering
