Parker 110A-129-AS-0 Hydraulic Motor Sae a Mount

Product Description

The PARKER 110A-129-AS-0 is a bi-rotational hydraulic motor designed for industrial and mobile hydraulic systems. It features a 12.9 cubic inch per revolution displacement and is rated for up to 2,250 psi maximum operating pressure. The motor mounts via an SAE A flange and accepts SAE thread port connections at a 7/8-14 port size. With a maximum speed of 437 RPM and a speed at maximum pressure of 858 RPM, this unit is suited for low-speed, high-torque drive applications. The 0.99-inch shaft diameter with a 0.62-inch keyway depth accommodates standard keyed coupling arrangements. Licensed hydraulic system technicians and industrial mechanics are the primary installers.

This motor is used in hydraulic drive circuits found in agricultural equipment, construction machinery, and industrial machinery where a compact SAE A mount envelope is required. The bi-rotational design allows shaft rotation in either direction without reconfiguring the motor, making it adaptable to reversing drive applications. Its Series 11 classification places it within a well-established family of gear-type hydraulic motors commonly specified in OEM and aftermarket hydraulic system builds.

Key Features

Compatibility

Designed as an OEM-style replacement or direct-fit hydraulic motor for systems specifying an SAE A flange mount, 12.9 cubic inch displacement, and 7/8-14 SAE thread ports within the PARKER Series 11 motor family.

Installation Notes

Installation should be performed by a qualified hydraulic technician familiar with high-pressure hydraulic circuits. Depressurize and lock out the hydraulic system completely before removing or installing any motor. Verify that port thread types, flange bolt patterns, and shaft dimensions match the existing drive assembly before installation. Follow applicable hydraulic system design standards and equipment OEM specifications for torque and flow requirements.
