Matching Relationships Matching the vibratory wheel drive shaft, eccentric shaft, and bearing housing, providing rotational support and axial positioning.

Compatibility and Applications

Compatible Parts: Core transmission components such as the vibratory wheel drive shaft and eccentric shaft of the CB-522/CB-524 paving compactor. Bears combined radial and bidirectional axial loads, suitable for high-frequency vibration and continuous operation, ensuring stable and efficient compaction and preventing component jamming and wear.

Application Scenarios: Suitable for long-term continuous operations such as road paving and subgrade compaction, including asphalt pavement compaction and subgrade layer compaction. Ensures smooth rotation of the vibratory wheel drive shaft and eccentric shaft, avoiding bearing loosening and wear due to vibration, reducing the risk of failure, and improving operational safety and reliability.

Compatible Use: Matching the vibratory wheel drive shaft, eccentric shaft, and bearing housing. The bearing assembly provides rotational support and axial positioning, and the shaft transmits power, adapting to long-term high-frequency vibration operation requirements and preventing component fatigue damage.

Installation and Maintenance Points

Installation: Clean the drive shaft and bearing housing, checking for scratches and burrs on the journal and housing surfaces; use heated installation (oil temperature 80-100℃) or a special press to evenly press in the bearing, ensuring good fit between the bearing and the shaft/housing, with axial clearance controlled at 0.05-0.15mm; after installation, tighten the lock nut to prevent axial movement.

Maintenance: Every 500 hours, check the bearing for abnormal noise, abnormal temperature rise, and seal leakage. Replace immediately if any abnormalities are found; regularly replenish lithium-based grease (NLGI 2) to ensure adequate lubrication and suitability for high-frequency vibration conditions.

Replacement: Disassemble the old part to check for wear on the drive shaft and bearing housing; repair if wear exceeds 0.1mm; before installing the new part, check the dimensions and roller condition to ensure consistency with original factory specifications. After installation, test for smooth rotation, no abnormal noise, and axial clearance meeting standards.
