SEW R87DRN160M4 Helical Inline Gearmotor
The SEW R87DRN160M4 is a heavy-duty inline helical gearmotor engineered for demanding industrial power transmission tasks requiring high mechanical power density, superior overhung load capabilities, and long operating service life[cite: 21]. Featuring robust thermal stability and versatile mounting styles (foot-mounted R87/RX107, B5/B14 flange RF87/RXF107, and solid shaft)[cite: 21], it is widely deployed across heavy conveyor systems, mining equipment, industrial agitators, and bulk material processing plants[cite: 21].

Expert Selection & Retrofit Engineering Notes
When retrofitting an existing application featuring an obsolete DT90, DV100, DV112, DV132, DV160, DV180, or DV200 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.
