HA6V107 Hydraulic Piston Motor HA6V107HD1DFZ2070 60110799

Product Overview

The HA6V107 bent-axis variable displacement hydraulic piston motor (Model Code: HA6V107HD1DFZ2070, Part Number: 60110799, from the HA6V series including HA6V80, HA6V107, and HA6V160) is engineered for demanding hydrostatic drives in both open and closed circuits. Built strictly to Rexroth A6VM/HA6V design standards, this motor offers 100% direct drop-in interchangeability. Serving as the vital actuator for crawler drives, winches, and rotary mechanisms, every unit undergoes 100% simulated full-load bench testing to guarantee exceptional volumetric efficiency, superior low-speed torque smoothness, and long-term operating reliability.

Key Technical Advantages

• 100% Direct Drop-in Interchangeability: Mounting flanges, spline shafts, and main hydraulic ports strictly conform to OEM specifications, allowing seamless plug-and-play replacement for Rexroth motors with zero pipeline modification.

• Spherical Valve Plate & Piston Design: Features a spherical lens shape valve plate paired with tapered pistons, providing automatic centering and superior sealing that minimizes internal leakage and optimizes low-speed torque stability.

• Wide Displacement Control Range: High ratio of maximum to minimum displacement ($V_{g\max}$ to $V_{g\min}$) enables a broad speed and torque output range, ideal for high-speed travel and heavy-load traction requirements.

• Heavy-Duty Bearing Arrangement: Equipped with high-capacity tapered roller bearings capable of absorbing severe radial and axial forces under continuous high-pressure shock loads.

Application Areas

• Earthmoving & Excavation Equipment: Crawler travel drives for excavators, directional drills, and foundation equipment.

• Lifting & Mining Machinery: Main/auxiliary winch drives for mobile cranes, rotary head drives for drilling rigs, and mining winches.

• Agricultural & Heavy Forestry Equipment: Drive systems for combine harvesters and off-highway tracked vehicles.

Expert Maintenance Tips

• Initial Housing Priming: Before the initial startup or after system service, fill the motor housing completely with clean hydraulic oil through the highest drain port. Operating the motor dry will cause immediate catastrophic wear.

• Fluid Cleanliness Management: Ensure system fluid is maintained at or above ISO 4406 19/17/14 cleanliness standards. Replace suction and return filters routinely.

• Case Pressure Control: Connect the case drain line directly to the oil reservoir without restriction, keeping internal case pressure well below the maximum limit (typically < 0.2–0.3 bar) to prevent shaft seal blowout.
