222 series

The 222 series bearing is a classic heavy-duty series of self-aligning roller bearings, which adopts a symmetrical spherical roller double row structure and is suitable for the strong radial load conditions of heavy equipment. At the same time, it can withstand certain bidirectional axial loads and has excellent self-aligning compensation ability. It is one of the most widely used self-aligning roller bearing series in industrial heavy-duty transmission.
