382300154 XCMG GR2605 motor grader copper sleeve

382300154 is a special copper bushing for transmission and actuator mechanisms in engineering machinery. Made of high-quality bronze, it features self-lubrication, wear resistance, and high load-bearing capacity. Used in shaft-hole mating areas, it reduces friction and wear, ensuring smooth operation of moving parts.

Core Functions and Roles

Friction Reduction and Wear Resistance: As a core friction pair component between the shaft and hole, it reduces frictional resistance generated by relative motion, reduces wear on the journal and mounting hole, and extends the service life of the moving pair and core components.

Positioning and Guiding: Precisely ensures the coaxiality of the shaft system and mounting base, acting as a positioning and bushing, constraining component displacement, ensuring the accuracy of mechanism movement, and preventing wobbling and misalignment caused by excessive clearance.

Buffering and Vibration Reduction: Absorbs vibration and impact during equipment operation, disperses stress concentration, reduces transmission system noise, and is suitable for heavy-load, high-frequency vibration operating conditions in engineering machinery.

Sealing and Protection: Used in conjunction with seals, it prevents dust, mud, lubricating oil, and other impurities from entering the friction pair, protecting the internal structure and reducing the risk of corrosion, jamming, and abnormal wear.
