Crossed Roller Bearings

The Cross Cylindrical Roller Bearings include the type with cage, type with separator and full complement type. The type with cage and the type with separator have a small coefficient of friction and are suitable for comparatively high speed rotations, while the full complement type is suitable for heavy load applications at low speed rotations.

The Cross Cylindrical Roller Bearings are square crossing arranged between outer ring and inner ring. The rollers linearly contact with the raceway, so it has higher rigidity and less elastic strain. The bearing can carry radial load, axial load and moment load simultaneously. They are especially suitable for the applications with high rigidity and high running accuracy.

The dimension of the inner and outer rings is a minimum to miniaturization. Especially, the extremely thin type is close to the limit of small size and has high rigidity, so it is optimal for applications such as joints and swiveling units of industrial robots, swiveling tables of machining centers, rotary units of manipulators, precision rotary tables, medical instrument, measuring instruments, IC manufacturing machines, etc.
