The types of tapered roller bearing
Aug 15, 2018

A single row tapered roller bearing has an outer ring and an inner ring assembly consisting of inner ring, tapered roller and cage.The outer ring can be separated from the inner ring assembly. Usually, the cone angle of the outer ring raceway of single row tapered roller bearing is between 10 °and 19 °, which can withstand the combined action of axial and radial loads at the same time.The greater the cone angle, the greater the ability to withstand axial load. In addition, single row tapered roller bearings can be installed to adjust the clearance.

 

The outer ring (or inner ring) of the double row tapered roller bearing is a whole. The two inner rings (or outer rings) are close to each other, with a spacer in the middle. The clearance is adjusted by the thickness of the spacer; the pre-interference of the double-row tapered roller bearings can be adjusted by the thickness of the spacer.

 

The performance of four row tapered roller bearing is basically the same as double row tapered roller bearing, but it bears more radial load than double row tapered roller bearing, and its limit speed is slightly lower, so it is mainly used in heavy machinery.
