Special Lubricated Chain

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

DURALUBE® Chain

For applications where regular lubrication is a challenge, DURALUBE can offer a longer lasting solution. This chain is constructed using a one-piece powdered metal bushing/roller combination which has lubricant drawn in under vacuum. In service, this lubricant is released and provides supplemental lubrication to the pin/bushing joint between regularly scheduled maintenance. Generally, the wear life of DURALUBE chain can be five times that of standard (initially lubricated only) chain.

RING LEADER® O-ring Chain

Diamond's Ring Leader O-ring chain is specifically designed for applications that don't permit regular lubrication, requiring the chain to depend entirely upon initial factory lubrication throughout its service life. Depending upon the specific conditions, Ring Leader can provide up to ten times the wear life of standard chain.

Industries such as agriculture, food processing, packaging, printing, textile and chemical processing can introduce contaminants that damage standard chain. Dirt, mud, food particles, paper fines, dust and moisture can cause buildup on the chain and clog the openings on standard roller chain where lubrication enters the pin/bushing area. These contaminants can even get inside the chain, actually damaging the surface of pins and bushings.

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.
