SEW R167DRN315S4 Helical Inline Gearmotor
The SEW R167DRN315S4 represents SEW-Eurodrive's flagship, maximum capacity inline helical gearmotor built to deliver peak torque output and extreme mechanical endurance[cite: 27]. Featuring heavy-wall cast iron housings, massive overhung load resistance, and premium thermal dissipation, it is available in foot-mounted (R167/RX167) and flange-mounted (RF167/RXF167) configurations for heavy mining conveyors, cement kiln machinery, steel rolling mills, power station drives, and large-scale bulk processing systems[cite: 27].

Expert Selection & Retrofit Engineering Notes
When retrofitting an existing application featuring an obsolete DV200, DV225, DV250, DV280, or DV315 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.
