What is the difference between 06B and 06C, European standard chain and American standard chain

What is the difference between 06B and 06C

The 06B chain is a short-pitch precision roller chain, and the chain plate is a straight chain.

06B straight chain

The 06C chain is a sleeve chain. The chain plate is "∞ word chain plate".

06C chain

In the data, the pitch of 06B chain and 06C chain is the same, both are 9.525mm, and 06C has no rollers. The roller diameter is replaced by the sleeve diameter.
