A6VM200EP2E/63W-VAB010HB-E Rexroth Motor

Product Overview

The A6VM200EP2E/63W-VAB010HB-E and A6VM160 HD1D/63W0800-VZB020B belong to the Bosch Rexroth A6VM series of high-pressure axial piston variable motors (bent-axis design, Series 63). Designed for open and closed circuit hydrostatic drives, displacement is infinitely variable from Vg max to near 0. Output speed depends on flow and displacement; torque increases with pressure differential and displacement. Fully interchangeable with original Rexroth interfaces and performance (100% match), every unit undergoes 100% simulated operating condition testing. Ideal for mobile and stationary applications, the series features precision bent-axis technology, excellent starting characteristics, wide speed range and high power density.

Key Technical Advantages

1. Precision bent-axis pistons and high-strength materials deliver high volumetric efficiency and power density, with continuous displacement adjustment to near zero.
2. Excellent starting characteristics and wide speed range: High starting torque, smooth low-speed operation and strong high-speed capability.
3. Long-life bearings and high reliability: Supports high pressure peaks and vibration for extended service life.
4. 100% simulated duty testing and full interchangeability: Exact match to original Rexroth interfaces and performance curves—true drop-in replacement with no modifications.
5. Flexible control options: Electric proportional (EP) and hydraulic proportional (HD) controls adapt to complex drive systems.

Application Areas

Travel and swing drives in construction machinery, agricultural equipment, cranes, rollers, mining machinery, marine auxiliary propulsion and stationary industrial hydrostatic systems requiring variable motors.

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 seals, control valves and bearings; perform moderate-load break-in initially. Strictly observe maximum speed and pressure limits. When replacing, verify the complete model code (including control and shaft options) for full interchangeability. Refer to official Rexroth data sheets (RE 91604) for precise torque-speed curves.
