Products Description
The SEW KA87-DRN132S4 represents a powerhouse in the helical-bevel category, specifically engineered for high-torque applications where space is at a premium. Driven by a 5.5kW (7.5 HP) DRN132S4 IE3 motor, this unit provides the perfect balance of raw mechanical force and premium energy efficiency.
As a dedicated Hollow Shaft (KA series) unit, the KA87 eliminates the need for expensive couplings and adapters, allowing for direct integration onto the machine's drive shaft. With a torque capacity reaching up to 2,700 Nm-nearly double that of the smaller KA77-this drive is the industrial benchmark for heavy-duty conveyor systems, mixers, and material handling equipment requiring a compact right-angle footprint.

Key Product Advantages
- Superior Torque Density: The KA87 utilizes a reinforced gear geometry that allows for high radial loads and extreme shock resistance in heavy-load environments.
- IE3 "Green" Compliance: Equipped with the DRN series motor, this unit significantly reduces carbon footprints and long-term electrical overheads.
- Zero-Maintenance Gearing: Unlike worm gears, the helical-bevel stage is virtually wear-free, ensuring the gearbox remains efficient for years without internal adjustments.
- Space-Optimized Geometry: The 90-degree right-angle design allows the motor to sit parallel to the machine, ideal for tight factory layouts.
- Universal Mounting: Available with various output flanges and torque arms to adapt to any mechanical interface.
Precision Components & Modular Kits
To maximize the lifespan of your SEW KA87 drive, we offer a range of specialized modular accessories tailored for high-performance environments:
- TorqLOC® Mounting System: A patented keyless hollow shaft connection that simplifies installation and prevents fretting corrosion, ensuring the unit can be removed easily after years of operation.
- BE11 Braking System: High-cycle safety brakes designed for the DRN132S4 motor, providing millisecond stopping accuracy for vertical lifts.
- FKM (Viton) Oil Seals: Upgradeable sealing options for high-temperature zones or chemical exposure areas to prevent lubricant leakage.

FAQ
Q: What is the benefit of the KA87 hollow shaft over a solid shaft (K series)?
A: The hollow shaft (KA) allows the gearbox to slide directly onto the driven shaft of your machine. This reduces the total footprint of the drive train and eliminates the maintenance required for external couplings.
Q: Can I use this unit with a Variable Frequency Drive (VFD)?
A: Yes. The DRN132S4 IE3 motor is fully compatible with VFDs for speed control. For low-speed operation, we recommend adding an external cooling fan to prevent motor overheating.
Q: Does the KA87 come pre-filled with lubricant?
A: Standard units are shipped with high-quality mineral oil. However, for food-grade or low-temperature environments, we can provide synthetic oil (CLP HC) upon request.
