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 .
Features
1,Spherical roller bearings can take, not only heavy radial loads, but also some axial loads in either direction. They have excellent radial load-carrying capacity and are suitable for use where there are heavy or impact loads.
2,Some berings have tapered bores and may be mounted directly on tapered shafts or cylingrical shafts using adapters or withdrawal sleeves.
3,Pressed steel and machined brass cages are used.

Quality Control:
We make all the beating according to the quality standard of ISO9001:2008 and ASME. We have our own in-house lab to test the material and bearing. Our strict testing and inspection system guarantee the high hardness, high abrasion and high temperature resistance, Before delivery, there will be a final and extra quality confirmation to ensure all the beatings in good order and condition .The quality of our products is good enough and they are warmly welcomed by many customers.
