SEW R47DRN90L4 Helical Inline Gearmotor
Brand: SEW-Eurodrive | Series: R-Series / RX-Series (Helical Inline)
The SEW R47DRN90L4 is a highly reliable inline helical gearmotor engineered for medium-duty industrial applications requiring high mechanical efficiency, durable thermal stability, and long operating service life[cite: 27]. Featuring versatile mounting styles (foot-mounted R47/RX67, B5/B14 flange RF47/RXF67, and solid shaft)[cite: 27], it is widely deployed across conveyor systems, packaging machinery, chemical mixing, and automated production machinery[cite: 27].

Expert Selection & Retrofit Engineering Notes
We specialize in providing complete drive packages and technical replacement solutions for the entire SEW-Eurodrive R47 series[cite: 27]. Whether you require a foot-mounted unit (R47 / RX67)[cite: 27], B5/B14 flange output (RF47 / RXF67)[cite: 27], or precision servomotor coupling, all mechanical designs can be supplied pre-assembled with state-of-the-art IE3 DRN series motors (DRN63M4 to DRN132S4)[cite: 27].
When retrofitting an existing application featuring an obsolete DT63, DT71, DT80, DT90, DV100, or DV112 motor[cite: 27], upgrading to an IE3 DRN motor ensures complete dimensional interchangeability while substantially reducing operating temperatures and energy costs. Simply send us your existing SEW serial number or nameplate code (including options like BE brake, TF thermistor, or RS backstop), and our engineering team will provide a 100% compliant replacement specification and quotation.
