A6VM170HA100000XD/71ARV0D4T11U0-S Rexroth A6VM Motor

Product Overview

The A6VM170HA100000XD/71ARV0D4T11U0-S 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, primarily Series 71). Designed for open and closed circuit hydrostatic drives, these motors offer continuously variable displacement from Vg max to near zero, covering a wide speed and high-torque range. Fully interchangeable with original Rexroth interfaces, controls and performance curves (100% match), every unit undergoes 100% simulated operating condition testing. Ideal for demanding mobile and industrial applications, the series combines precision bent-axis technology, high power density, excellent starting characteristics and long-life bearings for superior efficiency and reliability.

Key Technical Advantages

1. Precision bent-axis piston and high-strength materials deliver high volumetric efficiency and power density, with continuous displacement adjustment for high-speed light-load or low-speed heavy-load operation.
2. Wide control range and excellent starting characteristics: Displacement reducible to near zero; high starting torque and smooth low-speed running minimize shock and noise.
3. Long-life bearings and compact robust design: Approved for very high rotational speeds and pressure peaks, resistant to vibration in mobile applications for extended service life.
4. 100% simulated duty testing and full interchangeability: Exact match to original Rexroth interfaces, control codes 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 requirements, providing high torque at Δp = 450 bar.

Application Areas

Travel and swing drives in construction machinery, excavators, 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 correctly filled with oil and the case drain is connected before start-up to prevent dry-running damage. Use hydraulic fluid meeting recommended viscosity and cleanliness levels (ISO 4406). Periodically inspect control pressure, seals and bearings; perform moderate-load break-in initially. Strictly observe maximum inlet flow and speed limits to avoid overspeed. When replacing, verify the complete model code (including control and bearing options) for full interchangeability. Refer to official Rexroth data sheets (RE 91610) for precise torque-speed curves and load ratings.
