Application Scenarios

Common Faults & Troubleshooting

• Positioning deviation: Caused by support surface wear or deformation, resulting in component coaxiality deviation. Replace 3121543 support assembly.
• Looseness and abnormal noise: Caused by fatigue or cracking of fixed parts, resulting in operation vibration noise. Replace with new assembly and tighten to standard torque.
• Wear and seizure: Caused by strain on support contact surface or embedded impurities, leading to component operation seizure. Clean and replace support assembly.
• Fracture failure: Caused by severe impact or overload leading to support cracking. Replace immediately and check internal component damage.
