PSF - Linear guides
PSF - Profiled rail guides
Linear guides are designed with four raceways in O - arrangement. The precision steel balls transmit introduced forces at a contact angle of 45 degrees (see following sketch). In comparison to the X-arrangement, the O-arrangement gives a higher torsional rigidity.
To achieve an optimum at load capacity and stiffness the maximum number of steel balls were used, despite the limited space. As a result, high static and dynamic torque loads are possible. The same load ratings apply to all load directions with a compact design.
