SEW S67DRN132S4 Helical-Worm Right-Angle Gearmotor
The SEW S67DRN132S4 is a heavy-duty right-angle helical-worm gearmotor engineered for high-torque industrial applications requiring smooth, low-vibration operation and elevated mechanical durability[cite: 20]. By coupling a primary helical gearing stage with a precision worm gear wheel set, the S67 achieves significantly higher efficiency and higher thermal capacity than standard worm gear units[cite: 20]. Available in complete mounting styles (foot-mounted, B5/B14 flange, solid shaft, hollow shaft with keyway, shrink disc, and TorqLOC® keyless clamping system)[cite: 20], it is widely deployed in material handling systems, industrial agitators, wastewater machinery, and heavy automated processing lines[cite: 20].

Expert Selection & Retrofit Engineering Notes
When retrofitting an existing application featuring an obsolete DT71, DT80, DT90, DV100, DV112, or DV132 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.
