O Ring chain
The O ring chain is a specialized type of roller chain used in the transmission of mechanical power from one sprocket to another.
O-ring chains are most notably used in motorcycles, one of the most demanding applications for a metal chain. High rpm and heavy loads require bulky chains, but such engineering increases the effect of friction compared to lighter chains. So lubrication plays a vital role here, but the high rpm also make it very difficult to keep lubrication inside and on the chain. Additionally, motorcycle chains are exposed to a large volume of contaminants and particles and must be protected. O-rings, as described above, fit this application perfectly.
