XRBH series crossed roller bearings, with their unique structural design and excellent performance, play a vital role in the industrial field, especially in applications with strict requirements on precision, rigidity and load capacity.
Crossed roller bearings are a special type of roller bearing with rollers alternately arranged between the inner and outer rings. This design allows the bearing to simultaneously withstand loads from all directions, including radial, axial, and overturning moments. Compared to traditional single-row bearings, crossed roller bearings significantly save installation space and provide higher rotational accuracy and rigidity.
