SEW P072 Series Planetary Gearbox & Combination Gearmotors
The SEW P072 Series is an extra-heavy-duty industrial planetary gear unit engineered for high-capacity power transmission requiring high torque endurance (~200 kNm nominal torque rating) with superior thermal dissipation and shock resistance[cite: 19]. By mounting the P072 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 delivers massive overall reduction ratios, flexible spatial mounting (coaxial or right-angle), and maximum operational reliability for heavy apron feeders, bucket wheel reclaimers, industrial agitators, heavy shredders, winches, and mining conveyor drives[cite: 19].

Expert Selection & Retrofit Engineering Notes
When retrofitting an existing heavy application featuring an obsolete primary drive motor (DV225, DV250, DV280, or DV315)[cite: 19], 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.
