150901020081B028 Self-lubricating copper bushing Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The 150901020081B028 self-lubricating copper bushing is a core load-bearing and guiding component of the hydraulic cylinder. It supports the reciprocating motion of the piston rod, bears lateral loads, reduces metal-to-metal friction, and ensures smooth cylinder extension and retraction. The product is precision-machined from high-purity copper alloy and features a built-in self-lubricating structure. It is oil-storage, wear-resistant, and operates without jamming, making it suitable for heavy-duty operations such as earthmoving and mining.
This original factory-made copper bushing boasts precise dimensions, high coaxiality, a smooth inner wall, and standard clearance, ensuring zero wear during reciprocating operation. Its self-lubricating structure provides continuous oil supply to reduce friction, preventing dry friction of the piston rod, scoring, and seizing, while also buffering equipment vibration and improving cylinder operational stability. Old copper bushings are prone to lubrication failure, grooved inner walls, and increased clearance, leading to piston rod wobble, abnormal noise, seal wear, oil leakage, and pressure loss. This product is an original factory standard part, supporting in-situ non-destructive replacement, suitable for equipment maintenance and bulk stocking, quickly restoring cylinder fit accuracy, and reducing maintenance costs.
