Product Introduction

HMB125-T-FM3 hydraulic motor is one of the hatch cover hydraulic motors used in bulk carriers, standard product, short delivery cycle, Long service life, reliable performance, displacement 2050cm3/r, rated pressure 210bar, rated power 117KW. Hydrostatic balancing technology, with high efficiency, good starting torque and stable operation.

HMB125-T-FM3, with its core advantages of large displacement, high torque, and high speed, is a highly effective alternative to traditional electric motors or low-speed motors in medium- and high-voltage systems. Its flange mounting and compact design are particularly well-suited for space-constrained applications, making it widely used in construction machinery, specialized vehicles, and other fields.

Model Code Breakdown: HMB125-T-FM3

  • HMB: Staffa fixed displacement radial piston hydraulic motor

  • 125: Frame size / displacement code

  • T: Mounting flange type

  • FM3: Bearing and speed class (heavy-duty bearing version)

Key Features

  1. Fixed displacement design, no hydraulic shift function. Constant torque output proportional to system pressure.

  2. Hydrostatically balanced radial piston structure, excellent breakout torque, smooth low-speed rotation, high mechanical efficiency up to 94.1%.

  3. Robust heavy-duty construction, long service life, multiple shaft, port and seal options available.

  4. Optional built-in brake can be fitted on request.

Typical Applications

  • Marine: deck winches, anchor windlasses, marine cranes

  • Construction & mining: winch drives, crawler track drives, heavy slewing devices

  • Industrial: shredders, heavy conveyor drives, rotary equipment

Notes

  • HMB series = fixed displacement (one speed); HMC series = two-speed switchable displacement. Do not mix them up in system design.

  • Spare parts market supplies original Kawasaki Staffa units and aftermarket replacement HMB125-T-FM3 motors.

  • Confirm flange type, shaft dimension, brake requirement and seal material during selection.
