Domestic Replacement A10VM28, A10VM45, A10VM63, A10VE28, A10VE45, A10VE63 Axial Piston Hydraulic Motor
Product Overview
This domestic replacement Hydraulic piston motor series includes A10VM28, A10VM45, A10VM63, A10VE28, A10VE45, A10VE63. As variable displacement hydraulic motor, it serves as the core power component of the hydraulic system for heavy-duty mobile Machine. Adopting swashplate axial piston structure, this Hydraulic piston motor is engineered to replace the original Rexroth A10VM / A10VE series. It converts hydraulic pressure energy from the hydraulic system into rotary mechanical torque to drive walking, winch and transmission mechanisms of construction Machine.
A10VM is flange-mounted two-point control variable hydraulic motor, while A10VE is plug-in type variable Hydraulic piston motor. Both models support open circuit and closed circuit hydrostatic transmission. The domestic version keeps identical mounting dimensions, shaft size and oil port layout as the original unit, which enables direct replacement without modifying the existing hydraulic system.

Working Principle
High-pressure hydraulic oil delivered by the hydraulic system enters the cylinder block of this Hydraulic piston motor. The pressurized oil pushes pistons against the angled swashplate and generates rotary motion for the output shaft. By adjusting the swashplate angle, the hydraulic motor switches between large and small displacement, realizing two-stage torque and speed adjustment. When the Machine needs low-speed high-torque or high-speed low-torque working conditions, the hydraulic system sends pilot pressure signal to change motor displacement automatically to match load requirements. Heavy-duty bearings and precision piston pairs ensure stable rotation under continuous heavy load.
Core Advantages
1. Domestic replacement Hydraulic piston motor, same installation dimension as original, direct fit into the hydraulic system of Machine, no extra machining required.
2. Two-point variable displacement design, flexible switching between torque and speed, suitable for variable load working conditions.
3. Precision grinding piston and valve plate assembly, low internal leakage, high volumetric efficiency, less heat generation for the whole hydraulic system.
4. Robust cast housing and premium sealing components, strong resistance to shock, vibration and dust, reliable performance on construction sites.
5. Complete displacement options (28 /45 /63 cc). Cost-effective aftermarket spare parts, ideal for repair shops and global hydraulic spare part distributors.
Application Range
This series hydraulic motor is widely used as the drive component in hydraulic system of road rollers, pavers, mining equipment, crawler transport vehicles and other mobile engineering Machine. It is commonly used for hydrostatic travel drive, winch drive and overhaul replacement of the Machine.
