The following are the precautions for using a universal shaft:
Installation
Ensure correct alignment: The axes of the connected shafts should be within the allowable angular deviation range specified by the manufacturer to avoid excessive stress and wear.

- Tighten the mounting bolts/nuts firmly to prevent loosening during operation.
Operation
- Do not exceed the rated speed and torque of the universal shaft to avoid damage or failure.
- Keep the operating temperature within the recommended range; high temperature may affect the material properties and lubrication performance.
Monitor vibration and noise regularly. Abnormal vibration or noise may indicate misalignment, wear, or other problems.

Maintenance
- Regularly check the lubrication condition and replenish or replace the lubricant as required to reduce friction and wear.
- Inspect the universal shaft for wear, cracks, or deformation at regular intervals. Replace worn or damaged parts in a timely manner.
- After long-term storage or disuse, check and test the universal shaft before reuse to ensure its performance.
These precautions should be strictly observed to ensure the safe, reliable, and efficient operation of the universal shaft.
