INTRODUCTION

IHI Hydraulic Motors are widely used throughout the marine industry for converting hydraulic energy into mechanical rotational power. These motors play a critical role in deck machinery, cargo handling systems, steering gear units, hatch cover systems, winches, cranes, and offshore hydraulic equipment.

Known for their durability, reliability, and smooth torque output, IHI Hydraulic Motors continue to serve onboard commercial vessels, offshore platforms, shipyards, and marine industrial facilities worldwide.

SM MARINE SERVICE™ supplies IHI Hydraulic Motors, spare parts, repair services, overhaul support, and worldwide marine hydraulic technical assistance.

WHAT IS AN IHI HYDRAULIC MOTOR?

An IHI Hydraulic Motor converts pressurized hydraulic oil into rotary mechanical motion.

The motor receives hydraulic oil flow from a hydraulic power unit or hydraulic pump and transforms that energy into controlled rotational force.

These motors are commonly used where:

• High starting torque is required
• Continuous operation is necessary
• Precise speed control is important
• Heavy marine equipment must be operated safely

IHI Hydraulic Motors are trusted because they perform reliably even under harsh marine conditions.
