Efficiency improvements and two new sizes doubles torque available from Parker F12 hydraulic motor.

Parker Hannifin, the global leader in motion and control technologies, has broadened its proven range of F12 bent-axis hydraulic piston units, offering greater choice and flexibility in terms of size and operating options. Previously available in sizes up to 125 cc/rev, the new sizes of 150 and 250cc models double the theoretical torque availability whilst a reduction in interior friction of these high performance motors reduces operating temperature and noise levels, while improving reliability and productivity.

Designed to offer outstanding performance, efficiency and endurance, these latest heavy duty piston motors are ideal for both open and closed loop circuits in demanding industrial and offshore applications, including winches, pile drivers and cranes. Featuring a unique spherical piston design, the F12 Series motors offer exceptionally high shaft speeds with the capability of operating at pressures of up to 480 bar, while producing particularly high torque at both start-up and low speeds.

Featuring innovative piston lock technology and a minimal number of moving parts, the F12 Series piston motors are particularly robust, providing long service lives with exceptional levels of reliability. Parker’s unique timing gear design synchronises the shaft and cylinder barrel, meaning that the motors can tolerate high G-forces and torsional vibrations, while the heavy duty roller bearings ensure excellent external axial and radial shaft load capacity. Additionally, the 40° angle between the shaft and cylinder barrel allows for a particularly compact design.

The F12 Series motors also feature high precision valve plates for increased self-priming speed and low noise operation, with options for both left and right hand rotation. Moreover, the use of laminated piston rings ensures, low internal leakage and excellent thermal shock resistance and a long operating life.

With the addition of these latest models, the F12 Series bent-axis piston units are now available in a full range of sizes 23, 30, 40, 60, 80, 90, 110, 125, 150 and 250cc. Standard options for the motors include a choice of CETOP, ISO and SAE mounting flanges and shaft end configurations, with a compact Cartridge version also being available.
