150901020082B045 Self-lubricating copper bushing Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The 150901020082B045 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, isolates metal-to-metal friction, and prevents component scoring and wear. The product is made of high-purity copper alloy, which is hard and structurally stable. Combined with a built-in oil reservoir, it provides long-term friction reduction and eliminates the need for frequent oil replenishment, making it suitable for high-intensity, heavy-duty operations such as mining and earthmoving.
This original factory-made copper bushing boasts precise dimensions, high coaxiality, a smooth inner wall, and standard assembly clearances, ensuring smooth piston rod extension and retraction without wear or jamming. Its built-in self-lubricating structure provides continuous oil supply, preventing dry friction and seizing of the piston rod, buffering equipment vibrations, and improving cylinder operational stability. Older copper bushings are prone to lubrication failure, grooved inner walls, and increased clearances, leading to piston rod misalignment and 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 fitting accuracy and reducing maintenance costs.
