DYZV Spherical roller bearings

A self-aligning roller bearing is composed by an inner ring with a double raceway, an outer ring with a spherical surface, double-row spherical rollers and a cage. The outside raceway center is in accord with shaft center; all have self-aligning function, which can compensate the mounting error between the shaft and bearing seat and the outer ring inclination caused by shaft deflection. They can carry large radial load and certain double-direction axial load and particularly suitable for the applications with heavy load or vibration.

Structures

Self-aligning roller bearings have two types of structures:

 2000 0 type and 20000CA type.

20000 type (original code 3000) are non-asymmetric

spherical rollers, there are ribs in the center of the

inner ring; there are also two row of independent solid cages.

This type of bearings is especially suitable for the applications with high speed rotation
