How To Tell The Quality Of A Chain By Its Appearance

The quality of a chain can be determined by its appearance, which is a very intuitive method
1. Whether the inner/outer chain plates are deformed, cracked, or corroded
2. Whether the pins are deformed or rotated, or corroded
3. Whether the rollers are cracked, damaged, or excessively worn
4. Whether the joints are loose or deformed
5. Whether there are abnormal sounds or vibrations during operation, and whether the chain is in good lubrication condition
