Long Lasting O-Ring Roller Chain
Using an O-Ring roller chain dramatically increases a chain application's performance and working life. O-Ring roller chains are almost the same as ANSI roller chains dimensionally but are slightly wider because of the placement of o-rings within the link plates. We keep these chains in stock in standard ANSI sizes in our Economy Plus and Premier Series quality levels. If you do not see the size or type of o-ring chain you need, don't hesitate to get in touch with us! We are here to help!

O Ring Chain Quality Levels
Economy Plus O-ring roller chain performs well in most standard applications and will prevent dirt or debris from getting into the internal components of the chain. Though they are economically priced, these chains have a solid roller design for improved performance and use a high-quality lubricant that most o-ring chains in this price level wouldn't.
Premier Series (Premium) O-ring roller chains feature a premium quality extreme performance rubber o-ring within the link plates, a solid bushing solid roller design, heat-treated components, and hardened pins. These o-ring roller chains have the highest strengths of any o-ring chain out there. They also have the best performance and hold up the longest. In most applications, these o-ring roller chains also have a slight "silencing effect" of 3 decibels or less. These chains can operate up to 176°C, but if you need a high-temp chain, don't hesitate to get in touch with us.
Upgraded O-Ring Roller Chains
X-Ring roller chains
The
X-ring design has better functionality, durability and power loss versus o-ring chains.
