O-Ring Roller Chain & Links
O-ring roller chain has a longer lifespan over a traditional style roller chain. The o-ring chain uses a premium quality synthetic o-ring between the outer & inner link plates. This help seal and retain the lubricant in one of the bearing points of the chain. On top of holding lubrication in, the o-rings also help prevent abrasive material out of the joint, which helps minimize premature wear overtime. This chain is recommended for applications where standard re-lubrication is difficult and extremely dusty environments. We recommend that you periodically lubricate the chain to prevent the o-rings from drying out and cracking.
