Spherical roller bearings

Spherical roller bearings have one or two rows of spherical rollers and ball joint orbit of the outer ring. Two orbits of the inner ring form an angle and the axis of a bearing. Bearings are self-aligning
and can thus compensate for shaft misalignment due to the housing or shaft deflection. Due to these structural properties is basically
not be replaced in many imposed by other types of bearings. Spherical roller bearings can carry radial loads in addition to the high axial loads in both directions and its structures occupy a leading position in the market.    

Additional labeling:
K - with a tapered bore taper 1:12
W33 - circumferential groove with three lubrication holes in outer ring
C3 - Radial clearance larger than normal
J - steel cage
M - brass cage

Example of marking: 22205 E, 22206 E, 22206 W33J, 22206 KW33K, 22206 E K , 22207 E, 22208 E, 22209 E, 22210 E, 22211 E, 22212 E ...  
These markings are the same as for SKF bearings, bearings and for other manufacturers.
