The tapered rollers (with larger spherical end) of these bearings

are guided precisely by the integral flanges of the washers (shaft washer

and housing washer) with raceways..

When extended,the design makes the tapered raceway surfaces of the

Shaft washer and housing washer and the sliding surface of the rollers

converge towards to the same single point on the axle.

Single direction bearings can carry axial load in one direction

Double direction bearings can carry axial load in two directions.

The middle washer of double direction bearings is connected with the

shaft,but due to the clearance inside, a sleeve must be used to fix the

middle washer in the axial direction.

Applications of single direction bearings are mainly found in crane

hooks and rotating platformfor oil drilling,and double direction bearings

in the mill roil necks.
