RA、RB、RU、/crossed roller bearing for high precision applications

In crossed roller bearings, the crossed roller bearings are capable of withstanding radial load, axial load and moment load, because the cylindrical rollers are arranged perpendicularly to each other on the V-shaped groove rolling surface of 900 by the spacer block Direction of the load. The inner and outer rings are miniaturized and the extremely thin form is close to the limit and has a high rigidity. Therefore, it is most suitable for the joint and rotation parts of the industrial robot, the rotary table of the machining center, the rotating part of the manipulator, Precision rotary table, medical equipment, calculators, IC manufacturing equipment and other equipment.
Rotation accuracy: the bearings are arranged vertically between the rollers with isolation block, to prevent the roller tilt and the friction between the rollers, reducing the torque. In addition, the edge stress concentration or locking of the roller does not occur as compared with the conventional use of the steel sheet holder. Also, since the inner ring or the outer ring is a two-segmented structure, the bearing clearance can be adjusted to smoothly rotate with high precision even when the preload is applied.

Bearing characteristics:
1, high precision: Accuracy can reach P4, P2 level;
2, high rigidity: The series bearings are preloaded;
3, high load: can withstand axial load, radial load, overturning load.
4, small size: the small size of the bearing can save space for the host.

RB type (outer ring type, inner ring rotation)
This model is a cross-roller collar
Of the basic type, with a split outer ring, and with the main body of the integration of the inner ring. It is most suitable for parts requiring inner ring rotation accuracy.
For example, it can be used in the rotating part of the indexing table of the machine tool.
