SEW P012 Series Planetary Gearbox & Combination Gearmotors
The SEW P012 Series is a medium-large heavy-duty industrial planetary gear unit designed to deliver massive torque output (~36 kNm nominal torque) with outstanding thermal capacity and extreme mechanical rigidity[cite: 22]. By integrating the P012 planetary output stage with SEW's standardized primary gear units—including the K-Series (Helical-Bevel), R-Series (Helical), F-Series (Parallel Shaft), and S-Series (Helical-Worm)—this modular drive system achieves enormous gear ratios, flexible axial orientation, and unmatched performance in heavy apron feeders, bucket wheel reclaimers, industrial mixers, shredders, winches, and bulk material processing drives[cite: 22].

Expert Selection & Retrofit Engineering Notes
When retrofitting an existing heavy application featuring an obsolete primary drive motor (DV132, DV160, DV180, or DV200)[cite: 22], upgrading to an IE3 DRN motor ensures complete dimensional interchangeability while substantially reducing operating thermal stress and energy costs. Simply send us your existing SEW serial number or nameplate code (including options like BE brake, TF thermistor, or backstop), and our engineering team will provide a 100% compliant replacement specification and quotation.
