In cross roller bearings for cylindrical roller in a 90 degree V shaped groove rolling on the surface of the spacer blocks are vertically arranged, so the cross roller bearings can bear radial load, axial load and torque load and multi direction load. Inside and outside the ring size is miniaturized, thin form is close to the limit of small size, and has a high steel, so it is most suitable to industrial robot joint part and a rotating part, machining center of the rotary table, mechanical hand rotating part, precision rotary Taiwan, medical machine, calculator, IC manufacturing equipment etc. equipment.

Rotary precision: the vertical alignment of the bearing is arranged between the roller and the block, which prevents the mutual friction between the roller and the roller, and reduces the rotation torque. In addition, compared with the previous use of the steel plate, the edge stress concentration or the phenomenon of the locking of the roller will not occur. At the same time, due to the inner ring or outer ring is the two division of the structure, bearing clearance can be adjusted, even if the pre load is applied, but also to the high precision and smooth rotation.

Bearing characteristics:

1, high precision: precision can reach P4, P2 level;

2, high rigidity: the series of bearings are pre loaded;

3, high load: can bear axial load, radial load, overturning load.

4, small size: the bearing volume is small, can save space for the main engine.
