High Pressure A6VM107 Rexroth Hydraulic Piston Pump Motor for large crawler cranes

Product Overview:
The A6VM107 is a high-performance bent-axis design axial piston motor from the renowned Rexroth A6VM series. Designed for both open and closed hydraulic circuits, this variable motor delivers exceptional power density, reliable starting characteristics, and smooth operation under extreme loads . With a displacement of 107 cc/rev and multiple control options, it provides precise, stepless speed and torque adjustment for demanding mobile and industrial applications. This unit is a direct, high-quality replacement solution for original Rexroth equipment .

Technical Specifications:

• Model: A6VM107

• Type: Bent-axis design, variable axial piston motor

• Displacement: 107 cm³/rev (continuously variable from Vg max to Vg min) 

• Nominal Pressure: Up to 450 bar 

• Maximum Pressure: Up to 500 bar 

• Maximum Speed: 3500 rpm at Vg max; up to 5600 rpm at reduced displacement

• Design: Suitable for open and closed circuits 

• Mounting: SAE standard flange options available

• Weight: Approximately 48 kg 

Core Features:

• Bent-Axis Design: The robust angled shaft and conical piston design ensure high starting torque, excellent efficiency (up to 92% volumetric efficiency), and resilience against shock loads. The drive shaft can withstand radial loads .

• Wide Control Range: Displacement can be adjusted steplessly from maximum down to Vg min = 0, offering a broad operational speed range without needing a gearbox. The wide control range enables the variable motor to satisfy requirements for both high speed and high torque .

• High Power Density: Compact and lightweight construction delivers maximum power output in a minimal installation space, providing an excellent power-to-weight ratio .

• Multiple Control Options: Large variety of controls available (HD/HA/EL/DA/MO) to suit specific application needs, allowing customization to various system requirements .

• Optional Integrated Valves: Compatible with optional flushing and boost pressure valves, or integrated/attached counterbalance valves for enhanced functionality and load control .

• Durability: Engineered for long service life with robust bearings, good starting characteristics, and low inertia. Features a ball-contact distribution plate that automatically centers during rotation for high efficiency and low noise .

• High-Speed Capability: Approved for very high-speed continuous operation due to advanced seal design around piston rings and cylinder block .
