60348679 Return Disk Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The return plate is a key component for guiding the piston reset in a hydraulic system. It limits the movement trajectory of the piston ball head and assists the piston in completing the reciprocating reset motion. It can balance the force on the piston, correct the coaxiality of operation, prevent piston wobble and jamming, ensure smooth oil intake and discharge of the hydraulic assembly, stabilize flow and power output, and support the efficient operation of the equipment.
This SANY original return plate undergoes quenching hardening, precision grinding, and stress relief treatment, resulting in a smooth, fatigue-resistant, and wear-resistant surface, suitable for harsh working conditions such as high-pressure impact, high-frequency reciprocating, and heavy-duty operation. Old return plates are prone to wear and deformation, positioning failure, and surface scoring, leading to poor plunger reset, hydraulic leakage, power vibration, and movement jamming. In severe cases, this can cause abnormal noise from the assembly, unstable pressure, and equipment shutdown. This product can be replaced in situ without damage, suitable for maintenance, overhaul, and bulk stocking, quickly restoring hydraulic reset accuracy and reducing maintenance costs.
