The self-aligning roller bearing has a double row of rollers, the outer ring has a common spherical raceway, the inner ring has two raceways and is tilted at an Angle relative to the bearing axis. This clever structure makes it have automatic aligning performance, so it is not easy to be affected by the Angle of shaft and bearing box seat on the error or shaft bending, and is suitable for installation error or shaft deflection caused by Angle error occasions. In addition to the radial load, the bearing can also bear the axial load of bidirectional action.The inner hole of the aligning roller bearing has two kinds of cylindrical and conical, the taper of the conical cone hole is 1:30 and 1:12, the conical inner hole bearing is equipped with a tight sleeve or a discharge sleeve, and the conical inner hole aligning ball bearing can be conveniently and quickly assembled on the optical shaft or the ladder machine shaft.The models of self-aligning roller bearings are: self-aligning roller bearings (20000CC type); Taper hole aligning roller bearing (20000CCK type); Self-aligning roller bearing (20000CC/W33 type); Tapered hole aligning roller bearing (20000CCK/W33 type); Self-aligning roller bearings (20000CCK+H type) mounted on tight sets; There are 6 kinds of self-aligning roller bearings (20000CCK/W33+H type) mounted on the tight sleeve.
