Product Descriptio

This PC400-7 rotary motor is the rotary power assembly compatible with the 40-ton PC400-7 large-scale mining excavator. It adopts an integrated structure of axial piston motor combined with heavy-duty planetary reducer, perfectly matching the original hydraulic control system of the 7th generation model. As the core component of the vehicle's rotary drive, it is a key hydraulic accessory for mining stripping, major earthwork engineering equipment overhauls, fault replacements, and complete machine refurbishments.

The housing is made of thickened high-strength cast steel and is formed as a single piece. The core friction components such as pistons, flow distributors, planetary gears, and heavy-duty bearings have all undergone quenching hardening and ultra-precision grinding processes. They are highly wear-resistant, pressure-resistant, and shock-resistant. The complete set of oil-resistant and high-temperature-resistant sealing components can withstand the erosion caused by mining dust, mud water immersion, and drastic temperature changes throughout the day. This significantly reduces common faults such as excessive oil leakage from the motor, internal pressure relief, and power loss under heavy loads. The specifications of the flange installation holes, oil ports, and the position of the lifting rings are strictly in accordance with the original factory standards. It supports direct replacement of old parts in place without the need to modify pipelines, brackets, and other accessory components. The disassembly and assembly operations are time-saving and labor-saving.
