Sealed self-aligning roller bearings can improve operational reliability, reduce size, increase power density, extend the rated life of lubricants, and reduce overall operating costs.

Self aligning roller bearings have double row rollers, the outer ring has a shared spherical raceway, and the inner ring has two raceways that are tilted at an angle relative to the bearing axis. This clever construction endows it with automatic centering performance, making it less susceptible to errors or shaft bending caused by the angle between the shaft and the bearing housing. It is suitable for situations where installation errors or shaft deflection cause angle errors. This bearing can not only withstand radial loads, but also axial loads acting in both directions.
