GM SERIES

The GM Series by SAI Hydraulics features a range of high-performance radial piston hydraulic motors designed to deliver exceptional torque at low speeds. These motors are engineered for use in heavy-duty applications where durability, precision, and smooth operation are critical.

Product Description

The GM Series radial piston motors operate on the principle of hydrostatic balance, minimizing internal friction and maximizing efficiency. Their modular design supports configuration flexibility, allowing adaptation to specific application requirements. This includes integration of features such as multiple displacements, integrated brakes, and speed sensors.

Key Features

• Radial piston construction ensures smooth operation and high efficiency under varying loads

• High starting torque capability, suitable for direct drive systems

• Low-speed operation without torque loss or performance drop

• Modular assembly with customizable options for control and feedback systems

• Robust materials and surface treatments for extended service life in harsh environments

• High volumetric and mechanical efficiency, even at partial loads

Technical Specifications

• Displacement: Approximately 50 cc/rev to over 1,000 cc/rev (depending on configuration)

• Operating pressure: Up to 450 bar

• Speed range: Designed for low to medium RPM applications

• Torque output: Very high, proportional to displacement and pressure

• Mounting: Complies with ISO and SAE standards

• Shaft types: Available in keyed, splined, or custom versions

• Optional features: Dual displacement, integrated parking brake, flushing valve, speed sensors

Applications

The GM Series motors are suitable for a wide range of heavy-duty and precision-demanding tasks, including:

• Winch and reel drives

• Rotary actuators for offshore and marine equipment

• Track and wheel drives on construction or mining machinery

• Industrial automation and conveyor systems

• Hydraulic rotary drives in forestry and agricultural machinery
