380603418 XCMG GR2605 motor grader copper sleeve

High-strength brass sliding bearing sleeves possess self-lubricating, wear-resistant, and anti-seizure properties. They are used in the mating parts of moving shafts and holes in engineering machinery to reduce friction, wear, and vibration impact.

Core Functions and Roles

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

Positioning and Guiding: Ensures the rotational accuracy of the shaft system, constrains component displacement, ensures the stability of the mechanism’s movement, and prevents wobbling and misalignment caused by excessive clearance.

Buffering and Vibration Damping: Absorbs vibration and impact during equipment operation, reduces transmission noise and stress concentration, and is suitable for heavy-load and high-frequency operating conditions.

Sealing and Protection: Prevents impurities and dust from entering the interior of the friction pair, protects the internal structure, and reduces the risk of corrosion and wear.
