Dongsheng, Japan launched the cross-roller bearing means in the vertical configuration between the inner wheel bearing and the outer cylindrical roller. As a result, a bearing can be carrying the radial load, axial load and to rque. crossed roller bearing

Therefore, the combination of two ball bearings to enable the shaft support small lightweight. In addition, the elastic displacement caused by the load because of the cylindrical roller than the ball less so than when using multi-row ball bearing rigidity improved.

Especially in the field of robotics, import bearing products to the development of small high-functioning, for which the cross-roller bearings implementation of the development of miniaturization.
Dongsheng, Japan (NIPPON THOMPSON) listed a section thickness of 5.5mm cross-roller bearing ultra-thin cross-roller bearing CRBT series. There are inner diameter 20/30/40/50mm of four kinds. slewing ring bearing

Among them, the inner diameter of 50mm "CRBT505A" section thickness equivalent to 69% of the original imported products bearing CRBS series of roller bearings in the world s thinnest "products.

Bearing width of 5.0mm. 505A of the width equivalent to 63% of the original product. Weight, 505A for 38% of the original product, only 32.3g. spherical roller bearing
