How to measure chain size

Use a caliper or screw micrometer to measure the chain center distance, which is the distance between adjacent pins on the chain.
Measuring the chain size is important because different models and specifications of chains have different sizes, and choosing the incorrect chain may cause chain breakage or increased wear of the chain and gears. Proper chain sizing can also help determine the quantity required to replace a chain, avoiding wasted costs due to under- or over-quantity. The chain size is measured as follows:
1. Use a steel ruler or tape measure to measure the total length of the chain.
2. Determine the size of the chain according to the model and specifications of the chain.

Chain care and maintenance:
Proper chain care and maintenance can extend the life of the chain and reduce failures caused by chain wear. Here are some suggestions for chain care and maintenance:
1. Clean the chain regularly and use lubricant to lubricate it.
2. Regularly check the tension and size of the chain and replace the chain if necessary.
3. Avoid using gears that are too large or too small, which will cause uneven stress on the chain and accelerate chain wear.
4. Avoid overloading the chain, which will accelerate chain wear and breakage.
5. While using the chain, check the surface of the chain for scratches, cracks and other damage, and replace the chain if necessary.
