Axial-radial cylindrical roller bearings
Super-precision axial-radial cylindrical roller bearings (fig. 1) are commonly used to support rotary tables, indexing heads and multi-spindle heads on machining centres. SKF manufactures super-precision axial-radial cylindrical roller bearings for shaft diameters from 80 to 850 mm. Their internal design, together with close tolerance manufacturing processes, enables these bearings to attain radial run-out better than, and axial run-out close to, P4 tolerance class.
