Spherical Bearing Features

1) Spherical roller bearing  are principally provided with two rows of symmetrical spherical rollers and a commonsphere raceway in out ring.
2) With good self-aligning ability and can operate when the shaft deflection under load or the shaft deflection underload or the shaft misalignment in mounting, and their permissible aligning angle is 1 to 2.5 degree
3) This type of bearings has heavy load carrying capacity and anti-impact ability, in addition to radial loads, theyalso can carry axial loads in two directions
4) In general, this type of bearings permits a low limiting speed.

Double Row spherical Roller Bearing :

The outer ring of the self-aligning roller bearing is a sohere,which takes the bearing senter as its center,there are two raceway on the inner ring,which have certain angle with the axes,and it has favorable self-alignment function.Mainly it can be subjected to radial load and the axial load from any direction.It can be used for the equipment of mining,metallurgy,paper mill and construction.

Features of spherical roller bearing:

C: Stamped steel retainer and strengthened symmetric rollers for considerably higher load ratings;

CA: one piece brass retainer and strengthened symmetric rollers; 
        exchange with C design, especially for large size. 

MB: Two-piece precision-machined brass retainer and strengthened symmetric rollers; 
        equivalent to C design in load capacity.

CC: steel cage, replace traditionalbrass cage.

E: Third generation design to improve stress distribution for much longer service life 

TN: Nylon retainer.
