150901020083B031 Self-lubricating copper bushing Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The 150901020083B031 self-lubricating copper bushing is a core guide and wear-resistant component of the hydraulic cylinder. It is responsible for guiding and reducing friction during the reciprocating motion of the piston rod, isolating direct metal-to-metal friction, and reducing equipment wear. Made of high-toughness copper alloy with a self-lubricating medium, it has a smooth inner wall, low coefficient of friction, is pressure-resistant, wear-resistant, and not easily damaged, making it suitable for heavy-duty operations such as earthmoving and mining.
This original factory-made copper bushing boasts precise dimensions, tight tolerances, uniform assembly clearances, and stable guidance without jamming or abnormal noise. It features long-lasting self-lubricating properties, making it suitable for high-speed reciprocating motion. It operates smoothly even under low-oil or dry-running conditions, and is resistant to high temperatures, fatigue, and loosening/deformation. Old copper bushings are prone to lubrication failure, inner wall groove wear, and increased play, leading to cylinder jamming, wobbling, abnormal noise, and sealing leaks. This product is an original factory standard part, supporting in-situ non-destructive replacement, suitable for equipment maintenance and bulk stocking, quickly restoring guiding accuracy and reducing maintenance costs.
