Parker Hannifin’s new bent-axis hydraulic piston units are ideal for open- and closed-loop circuits in demanding industrial and offshore applications, including winches, pile drivers and cranes.

Now available in 150 and 250cc models, Parker’s F12 series motors feature an enhanced design to ensure lower loads of internal friction, reduce operating temperature and noise levels, and improve reliability and productivity.

Featuring a spherical piston design, the motors offer high shaft speeds with the capability of operating at pressures of up to 480 bar, while producing high torque at start-up and low speeds.

Featuring piston-lock technology and a minimal number of moving parts, the F12 Series piston motors are said to be very robust, providing long service life with high reliability.

Parker’s 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 high external-axial and radial-shaft-load capacity.

The 40deg 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 left- and right-hand rotation.

The use of laminated piston rings ensures low internal leakage, high 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 23, 30, 40, 60, 80, 90, 110, 125, 150 and 250cc sizes.

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 available.
