Products Description
The SEW K87-DRN132S4 is a heavy-duty industrial drive designed to deliver exceptional power density and mechanical reliability. Equipped with a 5.5kW (7.5 HP) IE3 premium efficiency motor, this unit bridges the gap between standard logistics drives and heavy process engineering.
The K87 series is engineered for durability, featuring a robust cast-iron housing and precision-finished gears that support a continuous 2,700 Nm output torque. Unlike smaller frames, the K87 is built to withstand significant radial forces and high-inertia start-ups, making it the preferred solution for large-scale conveyors, industrial mixers, and heavy-duty elevators where long-term uptime is critical.

Key Product Advantages
- Unmatched Power Density: The K87 offers nearly double the torque capacity of the K77, allowing for heavier loads without increasing the motor size disproportionately.
- IE3 Energy Optimization: The DRN132S4 motor significantly lowers electricity consumption and carbon footprint, ensuring compliance with global efficiency mandates.
- 90° Space Efficiency: The right-angle design allows for side-mounting, saving critical aisle space in manufacturing plants.
- High Overhung Load Support: Reinforced internal bearings allow the K87 to handle massive external forces from chain drives or belt pulleys.
- Low Maintenance Design: Helical-bevel gears operate with minimal friction, extending the lifespan of both the oil and the gear teeth.
Drive Accessories & Modularity
The K87-DRN132S4 can be customized for specific industrial environments with the following options:
- Forced Cooling Fans: Recommended for VFD applications at low speeds to prevent motor overheating.
- Integrated Brakes: BE11 spring-applied brakes for fail-safe stopping and holding power.
- Advanced Sealing: FKM (Viton) oil seals for high-temperature or chemically aggressive environments.
- Backstops: Integrated mechanical backstops to prevent backward movement in inclined conveyor systems.

- Mining & Construction: Feeder drives and small-scale primary crushers.
FAQ
Q: Is the K87 significantly larger than the K77 in terms of installation space?
A: Yes. The K87 features a larger housing (225mm center height vs 190mm for K77) and a 60mm shaft. It is designed for applications where the K77's 1550 Nm torque limit is insufficient.
Q: Can this unit be used with a Variable Frequency Drive (VFD)?
A: Absolutely. The DRN132S4 motor is fully compatible with VFDs. We recommend adding a forced cooling fan if the motor will run at low frequencies (below 25Hz) for extended periods.
Q: What oil is recommended for a standard indoor environment?
A: For standard ambient temperatures (0°C to +40°C), we recommend CLP VG220 mineral oil. For extreme temperatures, synthetic lubricants are available upon request.
