JHM Series radial piston hydraulic motors provide stable low-speed output for winches, deck machinery and heavy-duty hydraulic equipment.
Why Choose JHM Series Hydraulic Motors
- Stable low-speed performance: suitable for winch and deck machinery drive systems.
- High torque output: designed for heavy-load and continuous-duty hydraulic applications.
- Custom configuration: displacement, mounting, brake and valve options can be matched to the project.
• Fluid column technology design: fewer moving links, reduced friction and wear, ensuring very high mechanical and volumetric efficiency.
• High starting torque close to theoretical values, delivering full torque at startup and under heavy load.
• Ultra-low speed capability: stable, cog-free motion even below 1 rpm.
• Robust marine-grade construction: long life under salt-mist, shock loads, and harsh industrial environments.
• Flexible configurations: fixed, dual, or variable displacement options; customizable shafts, seals, and brakes.
• Compact radial piston architecture: excellent torque density and smooth power delivery.
