What are the differences?

First off, both standard roller chain and o-ring roller chain are manufactured to ANSI B29.1 chain standards. This means both style roller chains are manufactured to set dimensions, which allows both styles to run on the same sprockets. The main difference is that o-ring roller chain uses an o-ring between the inner and outer plates, whereas standard chain is open without any seal.

What Are The Benefits Of O-Ring Roller Chain

The o-ring chain is a sealed roller chain that helps keep lubrication in the main "bearing" area of the chain. This helps extend the overall life by reducing chain wear in critical parts of the chain. Another added benefit is that the o-ring keep abrasive material out of the bearing are that can prematurely wear out the chain. The sealed o-ring roller chain should be used on applications where standard re-lubrication is very difficult.
