Diamond Series | Maintenance Free Roller Chain

Diamond Chain's maintenance free roller chain series are intended for applications where regular lubrication is not possible or practical.

Duralube Chain

Diamond's DURALUBE® chains are designed for applications in which regular lubrication is impractical. DURALUBE® series Chains feature a one-piece powdered metal bushing and roller combination lubricated under vacuum providing supplemental lubrication between regularly scheduled maintenance.

Ring Leader O-ring Chain

Diamond's Ring Leader O-Ring chains are designed for applications in which regular lubrication is not possible. Ring Leader O-Ring Series Chains are constructed with rings that seal Diamond Chain's proprietary lubricant in and keeps contaminants out.

Dust Stopper Chain

The Diamond Dust Stopper series is specifically intended for applications that require the functionality of both the DURALUBE and Ring Leader O-Ring drive chain combining long term lubricating power with the contaminant protection of o-ring chain.
