Key Technical Advantages

• Multi-stroke Radial Piston Design: The cam-lobe geometry ensures smooth, ripple-free torque output. Unlike axial piston motors, the MS series maintains constant torque even at speeds as low as $1\text{ RPM}$, eliminating “stiction” or jerky movements.

• High Radial Load Capacity: The wheel motor configuration features reinforced bearings that allow the motor to act as a structural axle, supporting significant vertical and horizontal loads while simplifying chassis design.

• Advanced Valve Plate Technology: Utilizing flat valve distribution with precision-ground surfaces, we ensure minimal internal leakage. Coupled with 100% simulation testing, the motor delivers exceptional volumetric efficiency even at $450\text{ bar}$.

• Integrated Braking Solution: Supports the direct integration of a spring-applied, hydraulic-released brake at the rear, ensuring heavy-duty incline parking safety in a compact footprint.

Application Areas

• Construction Machinery: Skid steer loaders, telehandlers, and self-propelled aerial platforms.

• Agricultural Equipment: Combine harvesters, grape harvesters, and sprayers.

• Specialty Vehicles: Airport tugs, heavy-duty forklifts, and mining conveyors.

Expert Maintenance Tips

• Case Drain Connection: Always ensure the highest drain port is connected directly to the reservoir. The case pressure must not exceed $0.2\text{ MPa}$ to protect the shaft seal.

• Initial Priming: Before the first start, the motor case must be filled with clean hydraulic oil to prevent dry friction between the pistons and the cam track.

• Temperature Regulation: Because radial motors dissipate heat slowly at low speeds, keep the operating temperature between $30\text{ and }60\text{°C}$. Temperatures above $80\text{°C}$ will drastically accelerate seal wear.
