Crossed Roller Bearings

The structure of HIWIN crossed roller bearings consists of an outer and inner race, with rollers and roller spacers installed between them. The spacers between the rollers reduce friction, thereby decreasing rotational resistance. The contact area between the rollers is very large, which minimizes elastic deformation under load and extends the lifespan of the bearings. The rollers are arranged alternately at a 90° angle, allowing the bearing unit to withstand loads from multiple directions simultaneously. This extremely rigid and precise structure ensures accurate rotational motion.
