SEW R97DRN180M4 Helical Inline Gearmotor
Brand: SEW-Eurodrive | Series: R-Series / RX-Series (Helical Inline)
The SEW R97DRN180M4 is a heavy-duty inline helical gearmotor engineered for demanding industrial power transmission tasks requiring high mechanical power density, superior fatigue endurance, and long operating service life[cite: 22]. Featuring robust thermal stability and versatile mounting styles (foot-mounted R97/RX107, B5/B14 flange RF97/RXF107, and solid shaft)[cite: 22], it is widely deployed across heavy mining conveyors, crushing drives, agitators, and large processing plants[cite: 22].
