1221M Bearing

2013 high precision  Self-Aligning Ball Bearing

With the same center as the bearing, self-aligning ball bearing formed outer ring raceway can make self-alignment. Their rolling elements linearly come into contact with the raceways of inner ring and outer ring. The self-aligning Bearings can take great radial load.

Features :  
1. Self  aligning ball bearings are principally provided with two rows of symmetrical spherical rollers and a common sphere raceway in out ring, the two inner ring raceways are included at an angle to the bearing axis   2.With good selfaligning ability and can operate when the shaft deflection under load or the shaft deflection under load or the shaft misaligning 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, they also can carry axial loads in two directions

 4.In general, this type of bearings permits a low limiting speed.

Applications

 injection molding machines, crane hooks, vertical pumps.It is mainly applied in hydroelectric generator, vertical motors, propeller shafts for ships, jib cranes, rolling mail roll necks
