SEW P052 Series Planetary Gearbox & Combination Gearmotors
The SEW P052 Series is a high-torque capacity industrial planetary gear unit engineered for extreme power transmission demands (~124 kNm nominal torque rating) with severe shock load absorption and rigid housing endurance[cite: 26]. By mounting the P052 planetary 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 combination drive provides enormous overall reduction ratios, flexible spatial mounting (coaxial or right-angle), and long-term operating durability for heavy apron feeders, bucket wheel reclaimers, industrial mixers, heavy shredders, winches, and mining conveyor drives[cite: 26].

Expert Selection & Retrofit Engineering Notes
When retrofitting an existing heavy application featuring an obsolete primary drive motor (DV200, DV225, DV250, or DV280)[cite: 26], 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.
