Key Technical Advantages

• Wear-Compensating Disc Valve: The independent valve disc automatically adjusts for wear to maintain a tight seal against the manifold. This ensures consistent volumetric efficiency and prevents loss of power throughout the motor’s lifespan.

• Geroler® Power Element: By incorporating rollers in the gear set, internal friction is significantly reduced. This results in higher mechanical efficiency, superior startup torque, and ultra-smooth rotation at very low speeds.

• Premium Shaft Seal Integrity: Designed with high-pressure resistant materials, the shaft seal can handle elevated back-pressure, allowing for simplified hydraulic circuit designs without the constant need for a drain line.

• Heavy-Duty Bearing Support: Tapered roller bearings handle high radial loads (up to $13,000\text{ N}$) and axial forces, making these motors rugged enough for direct-drive wheel or winch drum applications.

Application Areas

• Material Handling: Conveyor drives, forklift attachments, and specialized lifts.

• Marine & Winch Drives: Anchor winches, deck cranes, and net haulers.

• Agriculture: Reel drives for harvesters, seeders, and feeder mixers.

• Construction: Compact loader drives, augers, trenchers, and sweepers.

Expert Maintenance Tips

• Pre-Fill Housing: Always fill the motor case with filtered hydraulic oil via the drain port before the initial startup to ensure the internal splines and bearings are lubricated immediately.

• Case Drain Utilization: For applications with frequent reversals or continuous high-duty cycles, using the external case drain port is highly recommended to dissipate heat and protect the shaft seal.

• Oil Cleanliness: Maintain fluid cleanliness to $\text{ISO 4406 19/17/14}$ or better. Contamination is the leading cause of Geroler set wear and torque loss.
