Your advantages High power density Long service life R37 ... R167 Reduced backlash option RM series, specially designed for agitating applications The tried and tested modular concept and our strict quality criteria allow SEW-EURODRIVE to provide a diverse range of torques and gear ratios with incomparably finely tuned gradings. This exceptional diversity sets new standards in this field of drive engineering. Available versions Single-stage or multi-stage Foot- or flange-mounted Foot- and flange-mounted Flange-mounted with extended bearing housing RX Series (single-stage) For high output speeds, the exclusively single-stage gear units RX57 to RX107 offer compact solutions for your system design. Technical data Gear unit reduction ratio [i] 1.30 ... 8.65 Output torque [Nm] ([in-lb]) 36 ... 830 (320 ... 7350) Motor power range [kW] ([hp]) 0.12 ... 45 (0.16 ... 60) R Series (two- and three-stage) The complete program of helical gearmotors provides the optimum size and power solution for every drive task. And for operators with a "weight-watching" issue, our multi-stage gear units provide have a particularly special solution. Thanks to their die-cast aluminum design, the models R07, R17 and R27 are three particularly efficient lightweights – ideal as satellite drives and for use in light machine constructions. Reduced backlash helical gear units are also available for particularly precise requirements. Technical data Gear unit reduction ratio [i] 3.21 ... 289.74 Multi-stage gear unit reduction ratio [i] 90 ... 27001 Output torque [Nm] ([in-lb]) 31 ... 18000 (270 ... 159310) Motor power range [kW] ([hp]) 0.09 ... 160 (0.1 ... 215) RM series RM gearmotors with extended output bearing hub are a special type of helical gear unit. They were designed especially for agitating applications and allow for high overhung and axial loads and bending moments. The remaining data corresponds to that of standard helical gearmotors. Technical data Gear unit reduction ratio [i] 4.29 ... 289.74 Multi-stage gear unit reduction ratio [i] 134 ... 27001 Output torque [Nm] ([in-lb]) 270 ... 18000 (2390 ... 159310) Motor power range [kW] ([hp]) 0.12 ... 160 (0.16 ... 214.56)
