Product Description
Small Roller Self Centering Bearing Brass Cage For Gearbox 22312CA/W33
Description:
ETR Small Size Spherical Roller Bearing 22312CA/W33, Brass cage, CC and E type steel cage can be available with us
Spherical rollers are put between the spherical raceway on the outer ring and the two grooves on the inner ring for these bearings. Since the center of the arc raceway on the outer ring is the same as the center of the whole bearing arrangement ,these bearings are self-aligned and automatically adjust the bending of the shaft and housing and the eccentricity.
The bearings can carry radial load and axial load in double directions. The especial radial load carrying capability makes these bearings suitable for heavy load and shock load carrying.
The tapered bore with adapter sleeve or withdrawal sleeve makes the mounting and dismounting on the shaft quite convenient.
