1 . Basic info
Spherical roller bearing Features
1) Spherical roller 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 axia
2) The bearings have good self-aligning 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 .
