Replacement Hydraulic Motor for Parker F12-080, F12-110
1. Product Overview
This replacement hydraulic motor is designed as a direct interchange spare part for Parker F12-080 and F12-110 series fixed displacement bent axis piston motors. It adopts classic bent axis structure, fully consistent with original installation dimensions, spline shaft specifications, port layout and mounting interface of Parker F12 series.
It is an economical aftermarket substitute for original Parker motors, widely used for maintenance and renovation of mobile machinery hydraulic systems.

3. Working Principle
High-pressure hydraulic oil enters the motor cylinder block and pushes pistons to generate axial thrust. The thrust acts on the inclined swashplate, producing torque to drive the output shaft rotation and convert hydraulic energy into mechanical energy.
The motor can realize forward and reverse rotation by switching the oil inlet and outlet directions. Optimized flow distribution structure reduces pressure loss and guarantees stable output torque under heavy load.
4. Core Advantages
1. Fully interchangeable with Parker F12-080 & F12-110; no modification required for pipelines, mounting base and control circuit during replacement.
2. Precisely matched internal friction pairs, low internal leakage and stable volumetric efficiency under long-term heavy-duty operation.
3. High pressure resistance, large starting torque, strong overload capacity.
4. Compact and lightweight structure, convenient for installation and field maintenance.
5. Stable performance at high rotating speed, low vibration and low noise.
6. Shorter delivery cycle and competitive cost compared with imported original Parker spare parts.
5. Application Range
This interchange bent axis piston motor is the core executing component of hydraulic systems. It is widely fitted on concrete mixer trucks, mining equipment, drilling rigs, construction machinery, marine hydraulic equipment and other mobile machinery originally equipped with Parker F12-080 or F12-110 motors.
