Product Description


Harmonic gear bearings Cross cylindrical roller structure, divided according to their use case split outer ring, the inner ring and the outer and inner rings integral whole two categories. Rolling element is a cylindrical roller, 90 ° to each other vertically aligned in a V-raceway. This configuration enables a single bearing can withstand the load axial load, radial load and overturning moment, etc. in all directions, has high bearing stiffness and rotation accuracy complex carrying capacity; these bearings are compact, comes with bearing mounting holes for easy installation directly to the customer, suitable for a variety of different types of harmonic reducer.

PRS series bearings designed for this robot manipulator with R & D and harmonic reducer cross roller bearings, and precision cross roller bearing the same internal structure, have high rigidity, high precision turning, colleagues and can withstand the joint in all directions load. Harmonic gear during operation, these bearings have a crucial role, bearing directly determine the accuracy of gear teeth in the wrong resistance movement, and therefore PRS harmonic gear bearings ensure accuracy of the overall state of the harmonic gear It played a crucial role.

SHF (SHG) model (overall outer, inner overall) outer and inner rings are integral structure, almost no effect on the performance of the installation, it is possible to obtain stable rotation accuracy and torque; suitable for SHF (SHG) series of all kinds reducer.
