Super-precision radial-thrust cylindrical roller bearings are commonly used to support rotary tables, indexing heads, and multi-spindle heads in machining centers. JOJI manufactures super-precision radial-thrust cylindrical roller bearings with shaft diameters ranging from 80 to 850 mm. The internal design of these bearings, combined with the precision-tolerance manufacturing process, results in radial runout better than P4 tolerance grade, while axial runout approaches P4 tolerance grade.
