RA Series Cross Roller Bearing(outer ring division type with inner rotating, thin section) This model is a compact type of model with extremely thin outer and inner rings. It is optimal for areas where the swiveling unit needs to be light and small. For example, the rotational part of industrial robots or manipulator.
Our cross-roller bearings, because the divided inner ring or outer ring, after the rollers and spacers are installed, is fixed with the cross-roller ring to prevent separation from each other, so install the cross-roller shaft It is easy to operate when ringing. Since the rollers are arranged in a cross, only one set of cross roller rings can bear loads in all directions. Compared with the conventional model, the rigidity is increased by 3 to 4 times. At the same time, because the inner ring or outer ring of the cross roller bearing has a two-part structure, the bearing gap can be adjusted, and even if preload is applied, high-precision rotational movement can be obtained.
The classification and model series of the crossed roller bearings we produce:
With the Cross-Roller Ring, cylindrical rollers are arranged crosswise, with each roller perpendicular to the adjacent roller, in a 90゜ V groove, separated from each other by a spacer retainer. This design allows just one bearing to receive loads in all directions including, radial, axial and moment loads.Since the Cross-Roller Ring achieves high rigidity despite the minimum possible dimensions of the inner and outer rings.
Compact, Highly Rigid Swivel Bearings ,Achieving a Superb Rotation Accuracy
It is optimal for applications such as joints and swiveling units of industrial robots,
swiveling tables of machining centers, rotary units of manipulators, precision rotary tables, medical equipment, measuring instruments and IC manufacturing machines
