Self-aligning roller bearing

These bearings have barrel-shaped rollers between the inner ring, which has two raceways, and the outer ring which has one spherical raceway. Since the center of curvature of the outer ring raceway surface coincides with the bearing axis, they are self-aligning in a manner similar to that of self-aligning ball bearings. Therefore, if there is deflection of the shaft or housing or misalignment of their axes, it is automatically corrected so excessive force is not applied to the bearings.

Details:

The self-aligning roller bearing has acenter of curvature as identical as the bearing centre and boasts the aligning performance,i.e.can align automatically in the case of shaft and housing deflection,without the burden imposed on the bearing.It can carry both the radial load and the bi-directional axial load,with the large radically loading capacity and applicable to the occasion of heavy load and impact load. Such bearing is widely applied to large mechanical equipments in metallurgy,mining,petroleum,papermaking and construction etc.

Features :   

    1) Self-aliging 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.
