Product Description

 Tapered  roller bearings are generally used to support combined load mainly consisting of  radial load. Their cups are separable for easy assembling. During mounting and using, radial clearance and axial clearance can be adjusted and preload mounting can be made.

Other size 

Tapered roller bearings  are generally of separable design and have tapered cone and cup raceway between which tapered rollers are arranged. Their design makes tapered roller bearings particularly suitable for carrying combined (radial and axial) load.

According to dimensional standard difference, tapered roller bearings can be grouped into metric and inch size series.
