SEW P Series Industrial Planetary Gearmotors
The SEW-EURODRIVE P Series industrial planetary gearmotors deliver ultra-high power density and exceptional torque performance in an extremely compact design. Engineered as a powerful combination of a planetary gear unit and a primary SEW gearmotor (typically K or R series), the P series covers a nominal torque range from 24 kNm up to 360 kNm. Operating with high torsional stiffness and overload capacity, SEW P series units eliminate the need for additional couplings and adapters, making them the gold standard for heavy-duty low-speed applications such as aprons, rotary filters, apron feeders, drying plants, and wastewater treatment equipment.
Available P Series Variants (Output Shaft & Combination Configurations)
The modular design of SEW P series planetary gearmotors allows for diverse mechanical combinations and mounting methods. Specify your desired model structure when requesting a quote (e.g., P042 RF.., P072 KF.., or P092):
- P.. (Solid Shaft): Solid output shaft with key or smooth solid shaft arrangement.
- PH.. (Hollow Shaft): Hollow shaft version with shrink disc for keyless friction-locked transmission.
- P..RF.. / P..KF.. (Planetary Gearmotors): Integrated combination pairing a planetary stage directly with a primary helical (RF) or helical-bevel (KF) gearmotor.
- P.. (Foot/Flange/Torque Arm): Versatile mounting options including foot mounting, B5 output flange, or integrated torque arm design for shaft-mounted installations.

Technical FAQs: SEW P Series Industrial Planetary Gearboxes
By mounting a standard SEW primary gearmotor (such as a K or R series) directly to the planetary input, the drive unit achieves extremely high gear ratios without requiring a separate high-speed intermediate stage or external coupling. This integrated planetary gearmotor solution maximizes compactness, reduces weight, and offers superior economic value.
The P Series is ideal when installation space is extremely limited and high torque is required at low output speeds. Because power is distributed across multiple planet gears, planetary units offer much higher power density and lighter weight compared to same-torque parallel or bevel-helical gearboxes like the X Series.
To ensure complete compatibility, please provide a photograph of the SEW Industrial Gearbox nameplate displaying the full type designation (e.g., P072 KF107 DRN160M4) and the 10-digit Serial Number. Our team will verify the planetary ratio, primary stage specs, hollow/solid shaft dimensions, and mounting arrangement for an exact match.
