Kawasaki Staffa HMB Series High Torque Radial Piston Motors

Product Overview: The Staffa HMB Series is a world-renowned standard for heavy-duty hydraulic motors, featuring an advanced Radial Piston design. These motors are specifically engineered for rigorous applications requiring smooth, high-torque output at extremely low speeds. This selection covers core configurations: HMB045/S/30, HMB150-S-11, HMB200/S/FM4, and HMB325/PT/S04/70. With exceptional volumetric efficiency and shock-load resistance, the HMB series is extensively utilized in marine deck machinery, injection molding machines, mining equipment, and large-scale winch systems.

Key Technical Advantages:

• Superior Low-Speed Smoothness: Advanced hydrostatic balancing technology ensures smooth, “creep-free” torque delivery even at rotational speeds as low as 1 RPM.

• Extreme Power Density & Torque: Capable of generating massive starting and running torque within a compact frame, ideal for heavy-duty load handling.

• Shock-Load Resistance & Longevity: Robust housing and wear-resistant internal components allow the motor to withstand frequent directional changes and sudden pressure spikes, significantly extending service intervals.

• Versatile Mounting Compatibility: Offers various shaft options (Splined S, Tapered, Keyed) and distributor configurations (e.g., FM4) to comply with major global industrial standards.

• Target Applications: Marine anchor windlasses, fishing winches, plastic injection screw drives, mining conveyors, and TBM auxiliary drives.
