SEW R77DRN132S4 Helical Inline Gearmotor
Brand: SEW-Eurodrive | Series: R-Series / RX-Series (Helical Inline)
The SEW R77DRN132S4 is a powerful, highly reliable inline helical gearmotor engineered for medium-to-heavy industrial applications requiring exceptional mechanical efficiency, superior overhung load capacity, and long operational service life[cite: 20]. Featuring versatile mounting styles (foot-mounted R77/RX97, B5/B14 flange RF77/RXF97, and solid shaft)[cite: 20], it is widely deployed across heavy conveyor lines, material handling equipment, industrial mixers, and processing machinery[cite: 20].

Expert Selection & Retrofit Engineering Notes
We specialize in providing complete drive packages and technical replacement solutions for the entire SEW-Eurodrive R77 series[cite: 20]. Whether you require a foot-mounted unit (R77 / RX97)[cite: 20], B5/B14 flange output (RF77 / RXF97)[cite: 20], or precision servomotor coupling, all mechanical designs can be supplied pre-assembled with state-of-the-art IE3 DRN series motors (DRN80M4 to DRN160M4)[cite: 20].
When retrofitting an existing application featuring an obsolete DT80, DT90, DV100, DV112, DV132, or DV160 motor[cite: 20], 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.
