Cross roller bearing is the roller bearing of which cylindrical rollers are evenly distributed by a spacer retainer on the rolling surface of a 90° V groove, with each perpendicular to the adjacent one. The construction enables it to carry radial, axial and moment loads in multi directions.
Besides, these bearings have a wide range of designs. The main difference is outer and inner ring structure as well as rotation types. That makes them apply to a variety of industrial applications.
Axis supplies cross roller bearing for industrial robot arm, machine tool spindle, medical instrument, and so on, with features of high rigidity, compact size and high rotation accuracy.
The most basic design of cross roller bearing. With the minimum possible dimensions of the inner and outer rings. Two separable outer rings while the inner ring is integrated with the main body. Furthermore, RA series comes with the thinner cross section based on the dimension of RB series.
Cross roller bearings with mounting holes, they don’t need the mounting flanges and housings. In addition, because they have the integrated inner and outer rings, the mounting procedure will not affect their performance, ensuring the stable rotation accuracy and torque.
Their construction is similar to the RB series. Having two separable outer rings which are connected by three locking rings, while the inner ring is integrated with the main body. They are usually used in the industrial applications where request a high rotation accuracy of inner ring.
Cross roller bearing with cage (CRBC series) or full complement without cage (CRB series). Come with two separable outer rings and one integrated inner ring. CRB is suitable for heavy loading applications, while CRBC series is suitable for the high speed ones.
With an integrated inner ring and an integrated outer ring, therefore, mounting procedure will not affect their performance, that guarantees the stable rotation accuracy and torque. Suit for both inner ring rotation and outer ring rotation.
