M5AF-018-2R01-B1W2 Parker Denison Vane Motor 18 cc 300 bar 4000 rpm

Product Overview

The M5AF-018-2R01-B1W2 is a Parker Denison M5AF Series heavy-duty hydraulic fixed displacement vane motor with a displacement of 18.0 ml/rev. This series is engineered for severe-duty applications requiring high pressure, high speed, and reliable performance under low fluid lubricity conditions.

The M5AF Series features a 12-vane design with a patented cartridge that ensures exceptionally low noise levels across the entire speed range. The vane, rotor, and cam ring are pressure-balanced to extend service life over the full speed range. The uni-directional version incorporates an internal valve that enables smooth dynamic braking, simplifies the hydraulic circuit, and eliminates the risk of motor cavitation.

As a premium aftermarket alternative to original Parker Denison hydraulic motors, this product offers 100% direct interchangeability with identical mounting dimensions and performance specifications, requiring zero modification to existing systems. Rotating groups may be easily replaced to renew the motor or change displacement to suit altered speed or torque requirements.

Every unit undergoes 100% simulated duty cycle testing prior to shipment, guaranteeing performance reliability under actual working conditions.
