ABSTRACT:
The structure of the cross roller bearing does not require fixing bolts, rivets or holders for the divided races and can firmly assemble the divided races together. The cross roller bearing includes the inner race having a raceway groove and an engagement surface on its outer circumferential surface and the outer race that fits over the inner race and has a raceway groove and an engagement surface on its inner circumferential surface. The outer race is divided into two axially divided races. A large number of rollers are installed in a raceway formed between the raceway grooves. The engagement surface of the inner race is formed with recessed portions at axially inner portions, and the engagement surfaces of the divided races of the outer race are formed with raised portions that rotatably fit in the recessed portions. Thus, the divided races are assembled onto the inner race so that they are rotatable but axially locked relative to the inner race.
