Output face dimensions match those of major manufacturers as well as standard NEMA dimensions, which gives users an alternative, cost-effective system. A full complement of tapered roller bearings handles high radial loads and output torque. This makes the PV suited for conveyor, production machinery, pharmaceutical and commercial packaging, medical-device manufacturing, automotive and demanding belt-and-pulley applications. A two-piece adapter/sleeve and the easy-to-access pinion clamp simplify mounting. The PV Series is available in six metric/NEMA frame sizes. These range from NEMA 17 to 34 and metric from 40 to 90 mm. Standard ratios are from 3:1 to 100:1.
