Cross roller bearings consist of cylindrical rollers arranged alternately at 90 degrees to each other. This arrangement enables the simultaneous absorption of radial, axial and tilting moments – with minimal installation space and high rigidity.
The crosswise guidance of the rollers distributes loads evenly in all directions, ensuring backlash-free and precise running behaviour. Their compact design and high dimensional stability make cross roller bearings particularly suitable for applications with high precision requirements, such as rotary tables, industrial robots, measuring devices and machine tools.
SKA® cross roller bearings offer excellent concentricity, long service life and easy integration into sophisticated system designs.
