 | Crossed roller bearings for complex loads
Designed with a large contact area where the rollers meet the raceway surfaces, crossed roller bearings (CRBs) from IKO exhibit exceptional rotational accuracy with less deflection under load. Many mechanical designs can benefit from the rigidity, accuracy, speed, and compact size that IKO CRBs provide, and they come in a wide choice of sizes and constructions to fit various rotating mechanisms. Machine tools, industrial robots, and medical equipment are only a few of many applications.
See all your options, including slim and super slim models, from IKO. |
