KYB MSF Series Motor | MSF-12, MSF-18, MSF-23, MSF-30, MSF-50 | Axial Piston Motor

KYB MSF Series High-Pressure Fixed Displacement Piston Motors

Product Overview: The KYB MSF Series is a high-performance axial piston motor featuring a bent-axis design, specifically engineered for the rigorous demands of construction and mobile machinery. Renowned for its ultra-compact frame and exceptional power-to-weight ratio, the MSF series is a global standard for excavator travel drives and crane winch systems. This selection covers the full displacement range: MSF-12, MSF-18, MSF-23, MSF-30, and MSF-50. Delivering smooth power at operating pressures up to 350 Bar, these motors provide perfect low-speed startup torque and efficient high-speed cruise capabilities.

Key Technical Advantages:

• Advanced Bent-Axis Engineering: The optimized bent-axis geometry provides a wider speed range and higher mechanical efficiency compared to swashplate designs, significantly reducing system heat generation.

• Exceptional Starting Efficiency: Specialized piston and valve plate design ensure extremely high mechanical starting torque under heavy loads, eliminating startup lag.

• Robust & Compact Architecture: Specifically lightened and dimensionally optimized for space-constrained excavator crawler frames and winch drums, simplifying the installation process.

• High-Load Bearing System: Reinforced internal bearings are built to withstand substantial radial and axial forces, ensuring an extended service life under frequent direction changes and shock loads.

• Target Applications: Mini and mid-sized excavator travel drives, rotary drilling rigs, marine winches, and crawler crane swing mechanisms.
