382300132 XCMG GR2605 motor grader steel sleeve

382300132 XCMG GR2605 motor grader steel sleeve

382300132 is a steel bushing for core transmission components in engineering machinery. Belonging to the category of sliding bearings, it primarily serves to provide shaft-hole fit, wear resistance, friction reduction, and positioning protection. It is compatible with the transmission and actuator mechanisms of engineering machinery equipment, ensuring the smooth operation of components.

Core Functions and Roles

Wear Resistance and Friction Reduction: As a friction pair component between the shaft and the hole, it reduces frictional resistance during relative movement, minimizes wear between the shaft and the mounting hole, and extends the service life of core shaft components.

Positioning and Fit: Precisely ensures the coaxiality and fit accuracy between the shaft and the mounting hole, acting as a positioning and bushing, constraining component displacement, and ensuring the precision of mechanism movement.

Buffering and Vibration Reduction: Absorbs vibration and impact during equipment operation, reducing noise and stress concentration in the transmission system, suitable for the vibration and heavy-load working conditions of engineering machinery.

Sealing and Protection: Used in conjunction with seals, it prevents dust, mud, lubricating oil, and other media from entering the friction pair, protecting the internal structure and preventing wear and corrosion.

Key Technical Parameters

Model: 382300132
Name: Steel Sleeve (Wear-resistant Steel Sleeve / Sliding Bearing Sleeve)
Suitable Scenarios: Shaft and hole mating parts of transmission mechanisms and actuators in engineering machinery

Material: High-quality carbon steel / alloy steel (heat-treated for strength, high hardness, wear resistance, and impact resistance)
Match Type: Interference fit / Transition fit, suitable for shaft and hole installation accuracy requirements

Operating Temperature: Adaptable to the normal operating temperature range of engineering machinery, stable performance in high and low temperatures

Core Features: Excellent wear resistance, high strength, easy installation, strong adaptability, and resistance to impact loads

Common Faults and Troubleshooting

Fault Symptoms: Abnormal noise from steel sleeve wear, excessive clearance, shaft hole scoring, and rotational jamming; in severe cases, it can lead to shaft deformation and transmission failure.

Troubleshooting Points: Stop the machine and check the wear degree of the inner and outer walls of the steel sleeve, and whether the mating surfaces are scored; check the clearance between the shaft and the steel sleeve to determine the wear condition.
