Possible causes:

• Misalignment between pulley and shaft
• Worn or damaged belt
• Loose mounting bolts
• Bearing failure or insufficient lubrication

Solution: Check alignment, inspect belt condition, tighten all bolts to specified torque, and ensure proper lubrication. If the issue persists, contact our technical support.

Installation steps:

1. Clean the shaft and bushing thoroughly
2. Position the bushing on the shaft at the desired location
3. Tighten the bushing screws gradually and evenly in a cross pattern
4. Apply recommended torque values (refer to product manual)
5. Verify secure mounting and check for proper alignment

Note: Never use excessive force. If installation is difficult, check shaft dimensions and bushing size compatibility.

Common causes:

• Excessive misalignment beyond specifications
• Overloading or shock loads
• Inadequate lubrication
• Corrosive environment without proper protection
• Improper installation or maintenance

Prevention: Ensure proper alignment, operate within rated capacity, follow maintenance schedules, and use appropriate protective coatings for harsh environments.

Recommended schedule:

• Daily: Visual inspection for obvious damage or misalignment
• Weekly: Check for unusual noise, vibration, or temperature
• Monthly: Lubrication check and bolt torque verification
• Quarterly: Comprehensive inspection and alignment check
• Annually: Complete disassembly, cleaning, and replacement of worn parts

Note: Adjust frequency based on operating conditions, load intensity, and environmental factors.

Immediate actions:

1. Stop operation immediately to prevent damage
2. Allow the component to cool down naturally
3. Check for overloading or excessive friction
4. Inspect lubrication levels and quality
5. Verify proper ventilation and cooling

Investigation: Check operating conditions, load capacity, alignment, and lubrication. If overheating persists, contact technical support for professional diagnosis.
