Poclain MS18 Series High-Torque Radial Piston Motors

Product Overview: The Poclain MS18 Series is the powerhouse for heavy-duty mobile propulsion and industrial transmissions. As a definitive Radial Piston Motor, the MS18 series utilizes a unique modular architecture to deliver massive, smooth torque output at ultra-low speeds. This featured selection includes precision configurations: MS18-2-621-F19-1720-27J0, MS18-2-G21-F12-1220-J000, and MS18-2-D21-A18-1220-DE00. Renowned for its superior load capacity and shock resistance, the MS18 is the premier choice for excavator travel wheels, harvester drives, marine winches, and rotary drilling rig chassis.

Key Technical Advantages:

• Elite Low Speed High Torque (LSHT): The radial piston architecture ensures full rated torque even at zero RPM or during startup, effectively eliminating “stick-slip” effects.

• Highly Integrated Modularity: Features integrated options for service brakes, parking brakes (multi-disc), and specialized bearing supports, significantly streamlining mechanical design.

• Multi-Displacement Capability: Supports dual-displacement functionality, allowing seamless shifting between “High Torque/Low Speed” and “Low Torque/High Speed” modes to optimize fuel efficiency.

• Peak Load & Pressure Resilience: Rated for continuous operation at 400 Bar (5800 PSI) with peak capabilities up to 450 Bar, handling extreme load fluctuations during digging or climbing.

• Rugged Service Life: Cam rings and piston assemblies are precision-machined from high-strength alloys, ensuring extended maintenance intervals even in harsh mining and offshore environments.

• Target Applications: Skid steer loader propulsion, harvester drives, offshore winches, railway maintenance equipment, and road construction machinery.
