Key Technical Advantages:

• High Start-up Torque: Utilizing advanced gear geometry and axial pressure compensation, these motors deliver massive start-up torque at low speeds, effectively overcoming inertial resistance in heavy-duty applications.

• Shock-Load Resilience: Internal bearing assemblies utilize ultra-wear-resistant materials, reinforced to withstand the pressure spikes common in heavy-duty duty cycles, significantly extending the motor’s service life.

• High Volumetric Efficiency: Precision-ground side plates and gear faces ensure superior sealing under pressure, minimizing internal leakage and maintaining consistent torque output even at low operating speeds.

• Low-Noise Operation: Optimized gear-meshing parameters significantly reduce vibration and pulsation noise, making these motors ideal for construction vehicles and indoor automation systems where acoustic signatures are monitored.

Application Areas:

• Construction Machinery: Track drive motors and swing drive systems.

• Specialized Utility Vehicles: Hydraulic systems for dump trucks, lifting, and auxiliary power.

• Agricultural Machinery: Drive systems for seeders and harvesters.

• Industrial Conveying: High-torque conveyor belts and mixing equipment drives.

Expert Maintenance Tips:

• Case Drain Installation: For bidirectional or high-pressure systems, always connect the motor’s case drain to reduce back-pressure on the front shaft seal, preventing premature seal failure due to thermal stress.

• Start-up Priming Sequence: After installation, fill the motor through the inlet port and manually rotate the shaft to ensure internal lubrication. Start at low pressure to purge all air before increasing to operating load. Never operate dry.

• Fluid Cleanliness Management: To maintain the precision clearance between gears and side plates, we strongly recommend 25μm (or finer) filtration, maintaining fluid cleanliness at ISO 4406 18/16/13. Regular oil analysis is advised as degraded fluid can accelerate internal wear.
