Parker Series F11 Bent Axis Piston Motor

Parker F11 Series Bent Axis Piston Motors

Parker’s Series F11 bent axis piston motors are engineered for superior efficiency, durability, and performance in demanding mobile and industrial applications. Featuring Parker’s unique spherical piston concept, these high-efficiency bent axis piston motors provide exceptional resistance to thermal shock while maintaining maximum output and reliability under extreme operating conditions.

Designed for both open- and closed-loop hydraulic systems, Parker’s advanced bent axis technology allows for operating pressures up to 420 bar (6,100 psi) and speeds up to 14,000 rpm. The combination of gear synchronization and double tapered roller bearings ensures smooth operation, high reliability, and long service life, even in harsh environments.

Available in displacements from 5 cc to 19 cc, these compact motors deliver excellent power density and uptime. Parker’s continuous product development and rigorous testing guarantee that each bent axis piston motor operates at optimum efficiency and meets the highest standards of performance and durability.
