R series helical gear units: high efficiency and wide range of gear unit ratios

Helical gear units are the "hidden classics" in our gear unit portfolio: 6 single-stage and 15 two- and three-stage frame sizes cover a torque range from 50 to 20 000 Nm. This gear unit series is also far ahead in terms of gear unit ratios: from i = 1.30 to i = 289.74, in double gear units even i = 27 001. Torque ratings and gear unit ratios this finely stepped are hard to find in the market.

The demand for high output speeds or low weight is met by the R gear units as well, of course. Always with a high level of efficiency, our helical gear units offer an optimum ratio between torque output and installation space. This means: a helical gear unit almost always fits your application.

Only half the solution without a motor? Then use our modular concept and combine the gear units of the R series with an AC motor to a R..DR.. helical gearmotor, or with a servomotor to an R..CMP helical servo gearmotor of your choice. Or simply choose the separate AC motor or servomotor that meets your requirements.
