SEW P102 Series Planetary Gearbox & Combination Gearmotors
The SEW P102 Series is the largest standard size in SEW's P-series industrial planetary lineup, designed for maximum torque transmission (~500 kNm nominal torque rating) under severe shock load and continuous heavy-duty industrial operating conditions[cite: 22]. By mounting the P102 planetary stage with SEW's modular primary gear units—including the K-Series (Helical-Bevel), R-Series (Helical), F-Series (Parallel Shaft), and S-Series (Helical-Worm)—this combination drive provides extraordinary overall reduction ratios, right-angle or coaxial layout flexibility, and top-tier reliability for heavy apron feeders, bucket wheel reclaimers, industrial mixers, heavy shredders, winches, and mining conveyor drives[cite: 22].

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