SEW R67DRN100L4 Helical Inline Gearmotor
Brand: SEW-Eurodrive | Series: R-Series / RX-Series (Helical Inline)
The SEW R67DRN100L4 is a robust, highly versatile inline helical gearmotor engineered for medium-to-heavy industrial applications requiring high mechanical power density, durable thermal stability, and long operating service life[cite: 21]. Featuring versatile mounting styles (foot-mounted R67/RX87, B5/B14 flange RF67/RXF87, and solid shaft)[cite: 21], it is widely deployed across conveyor systems, packaging machinery, chemical mixing, and automated production machinery[cite: 21].

Expert Selection & Retrofit Engineering Notes
We specialize in providing complete drive packages and technical replacement solutions for the entire SEW-Eurodrive R67 series[cite: 21]. Whether you require a foot-mounted unit (R67 / RX87)[cite: 21], B5/B14 flange output (RF67 / RXF87)[cite: 21], or precision servomotor coupling, all mechanical designs can be supplied pre-assembled with state-of-the-art IE3 DRN series motors (DRN71M4 to DRN160M4)[cite: 21].
When retrofitting an existing application featuring an obsolete DT71, DT80, DT90, DV100, DV112, DV132, or DV160 motor[cite: 21], 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.
