PARKER Hannifin’s new bent- axis hydraulic piston units are designed for open- and closed- loop circuits in demanding industrial and offshore applica tions, including winches, pile drivers and cranes.
Available in 150 and 250cc models, the F12 series motors are said to ensure lower loads of internal friction, reducing oper ating temperature and noise lev els, and improving reliability and productivity, according to the company.
The units include a spherical piston design that 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. Piston-lock technology and a minimal number of moving parts are also features.
According to Parker, the use of laminated piston rings ensures low internal leakage, high ther mal-shock resistance and a long operating life, while robust pis ton motors provide long service life with high reliability.
The F12 Series bent-axis pis ton units are now available in 23, 30, 40, 60, 80, 90, 110, 125, 150 and 250cc sizes.
