HA6V160 Rexroth Hydraulic Motor HA6V160HA2HFP1039B 450 Bar

Product Overview

The HA6V160 bent-axis variable displacement hydraulic motor (covering model codes HA6V160HA2HFP1039B, HA6V160HA2HFZ1039B, and HA6V160HA2HFS1039B, from the HA6V series including HA6V80, HA6V107, and HA6V160) is engineered for high-pressure open and closed circuit hydrostatic drives. Manufactured strictly in accordance with Rexroth A6VM/HA6V engineering standards, this motor guarantees 100% direct drop-in replacement. Serving as a high-performance actuator for crawler travel drives, winch systems, and rotary mechanisms, every unit undergoes 100% simulated full-load factory bench testing to deliver uncompromised volumetric efficiency, smooth low-speed torque, and exceptional reliability in extreme applications.

Key Technical Advantages

• 100% Direct Drop-in Interchangeability: Precision-machined mounting flanges, shaft splines, and hydraulic fluid ports match Rexroth OEM specifications exactly, enabling seamless plug-and-play replacement with zero pipeline modification.

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

• Wide Displacement Ratio: Stepless variable displacement control from $V_{g\max}$ to $V_{g\min}$ allows for a broad speed and torque range, fulfilling dual demands for heavy-traction crawling and high-speed roading.

• Heavy-Duty Tapered Bearing Assembly: Equipped with high-capacity tapered roller bearings capable of absorbing severe radial and axial shock loads encountered during continuous high-pressure operations.

Application Areas

• Earthmoving & Construction Equipment: Tracked travel drives for heavy excavators, rotary drilling rigs, and crawler cranes.

• Mining & Hoisting Machinery: Main/auxiliary winch drives for mobile cranes, mining winches, and marine offshore deck equipment.

• Forestry & Off-Highway Machinery: High-torque hydraulic propulsion for heavy forestry harvesters and off-road vehicles.

Expert Maintenance Tips

• Case Priming Prior to Start-up: Before initial operation or after maintenance, fill the motor casing completely with clean hydraulic oil via the highest drain port. Operating the motor dry will cause immediate wear and seizure.

• Fluid Cleanliness Management: Ensure system fluid is strictly maintained at or cleaner than ISO 4406 19/17/14 standards. Routinely service suction and return filters.

• Case Drain Pressure Limit: Ensure the case drain line routes directly back to the reservoir without restriction, keeping internal casing pressure strictly within allowable limits (typically < 0.2–0.3 bar) to prevent shaft seal failure.
