60348680 Spherical Bushing Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The spherical bushing is a key sliding support component in the hydraulic assembly. It mainly works in conjunction with the plunger, steel ball, and return plate to achieve linkage. Relying on the adaptive structure of the spherical surface, it compensates for operational deviations and buffers vibrations and offset clearances during equipment operation. It can effectively reduce sliding friction loss, correct the coaxiality of component operation, prevent jamming, uneven wear, and oscillation, ensure smooth reciprocating motion of the hydraulic plunger, and stabilize system flow and power output.
This SANY original spherical bushing undergoes quenching hardening, precision spherical grinding, and stress relief treatment. Its rounded and regular spherical surface, uniform clearance, and strong fatigue and wear resistance make it suitable for harsh working conditions such as high-pressure impact, high-frequency reciprocating motion, vibration offset, and continuous heavy loads. Old bushings are prone to problems such as spherical wear, delamination, scoring, deformation, and loose clearance, leading to piston jamming, hydraulic leakage, power vibration, and unstable pressure. In severe cases, it can cause abnormal noise from the assembly, uneven wear of components, and equipment downtime. This product supports in-situ non-destructive replacement, is suitable for maintenance, overhaul, and bulk stocking, quickly restoring the accuracy of the hydraulic assembly and reducing maintenance losses.
