A6VM160HA1TD/63W-VZB380A-SK Rexroth A6VM Motor

Product Overview

The A6VM160HA1TD/63W-VZB380A-SK and related models (A6VM80, A6VM107, A6VM115, A6VM170, A6VM215) belong to the Bosch Rexroth A6VM series of high-pressure axial piston variable motors (bent-axis design). Engineered for open and closed circuit hydrostatic drives, these motors feature continuously variable displacement from Vg max down to near zero, covering high-speed and high-torque requirements. Fully interchangeable with original Rexroth specifications and interfaces (100% dimensional and performance match), each unit undergoes 100% simulated operating condition testing. Ideal for demanding mobile and stationary applications, the series delivers high power density, excellent starting characteristics, compact robust construction and long service life through precision manufacturing.

Key Technical Advantages

1. Precision bent-axis piston and high-strength materials for high volumetric efficiency and power density, enabling continuous displacement adjustment for high-speed light-load or low-speed heavy-load operation.
2. Wide control range and excellent starting characteristics: Displacement can be reduced to near zero; high starting torque and smooth low-speed running reduce shock and noise.
3. Long-life bearings and compact robust design: Approved for very high rotational speeds, withstands high-pressure peaks and vibration in mobile applications for extended service life.
4. 100% simulated duty testing and full interchangeability: Exact match to original Rexroth interfaces, controls and performance curves—true drop-in replacement with no modifications.
5. Versatile control options and high torque output: Flexible HA/HD/EP controls adapt to system needs, delivering high torque at Δp = 400 bar.

Application Areas

Travel drives in construction machinery, excavator swing drives, cranes, rollers/compactors, agricultural machinery, mining equipment, marine propulsion and stationary industrial drives requiring high-pressure variable motors for wide speed ratios and high torque.

Expert Maintenance Tips

Ensure the housing is properly filled with oil and the case drain is connected before start-up to prevent dry running. Use hydraulic fluid meeting recommended viscosity and cleanliness (ISO 4406). Periodically check control pressure and seals; perform moderate-load break-in initially. Observe maximum allowable inlet flow and speed limits to avoid overspeed. When replacing, strictly verify the complete model code (including control and bearing options) for full interchangeability. Refer to official Rexroth data sheets (e.g., RE 91604) for precise torque-speed curves and load ratings.
