1 The 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 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 The bearings have 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.
