M4D-102-3N00-B502 Hydraulic Vane Motor
1. Product Overview
M4D-102-3N00-B502 is a fixed-displacement high-speed vane hydraulic motor from Parker Denison M4D series, adopting fully pressure-balanced vane structure and external drain design. It features compact size, low noise, stable torque output and strong resistance to external radial load. Widely used in industrial hydraulic systems, machine tools, packaging machinery, conveyors and auxiliary driving equipment, it is a high-performance alternative to original Denison vane motors.
