Self-aligning roller bearing 1. GCR15 2. ABEC-4 3. ISO9001: 2008 4. Carton, and wooden box packing Self-aligning roller bearing has two rows of spherical rollers, the outer race is provided with a common concave spherical raceway, while the inner race is provided with two concave spherical raceways that form an angle with the bearing axis. The curvature center of the outer raceway is consistent with the bearing center. The self-aligning roller bearing is self-adjusted, and it is not affected by non-centering or shaft deformation flexure of shaft and bearing block, so it can compensate the concentricity error caused by these reasons. Except being subject to radial load, this type of bearing can also be subject to bidirectional axial load and their combination load. The load capacity is large, and the bearing is provided with preferable shock resistant capacity. Self-aligning roller bearings are mainly applied on mechanical equipments of steel, mine, paper making, shipping, textile machinery, coal mill and electric power industries. It is one of the bearings most widely used in mechanical industry. The type are as below: 23220CAKF3/W33 22317/W33 24018CA 22317ACA 24022CA 22317C 24022CA/C3W33 22317C/W33 24022CA/C4S0W33 22317CA 24022CA/W33 22317CA/C3 24024CA 22317CA/C3W33 24024CA/C3W33 22317CA/W33 24024CA/C4S1W33 22317CAF3 24024CA/W33 22317CAK
