RU type cross roller bearing

cross roller bearings are also called cross roller bearings. Rolling bodies generally use cylindrical rollers or tapered rollers to cross and arrange each other on a single raceway. The rollers and rollers are separated by retainers or isolation blocks. High rotation accuracy, large load-bearing capacity, small size, high rotation speed and rigidity, and superiority that other bearings cannot match. This cross-arranged roller structure enables a single bearing to bear axial load, radial load and overturning moment. Compared with traditional structural bearings, the rigidity is increased by 3 to 4 times. At the same time, the external dimensions of this series of bearings are miniaturized to a large extent. The thin structure is close to the miniaturization size and has high rigidity, therefore, it is suitable for application occasions such as joint parts or rotating parts of industrial robots, rotating tables of machining centers, rotating parts of manipulators, rotating tables, turrets, medical instruments, etc.
RU type cross roller bearing (inner ring integral, outer ring integral, inner and outer ring with mounting holes)
Since the outer ring and the inner ring are equipped with mounting holes, there is no need to fix the flange and support seat during installation. Since the outer ring and the inner ring are of an integral structure, installation has almost no effect on performance, so stable rotation accuracy and torque can be obtained., Suitable for occasions when the outer ring and the inner ring rotate.
Main models of RU type cross roller bearings:
RU28, RU42, RU57, RU66, RU85, RU124, RU148, RU178, RU228, RU297, RU445
