Axial-radial cylindrical super-precision roller bearings can accommodate radial loads, axial loads in both directions and moment loads, whether acting singly, or simultaneously, in any combination. With high running accuracy, high load capacity and rigidity, SKF super-precision axial radial cylindrical roller bearings are ideal for rotary tables, indexing heads, and multi spindle heads. The bearing minimizes noise, vibration and heat generation.
