Maintenance Free Roller Chain / Special Lubricated Roller Chain

In some applications, regular lubrication of chains is neither possible nor practical. That’s why Diamond Chain developed a line of maintenance free roller chain designed to ensure optimal chain performance for those circumstances.

DURALUBE® Chain

For applications where regular lubrication is a challenge, DURALUBE offers a longer-lasting solution. Constructed using a one-piece powdered metal bushing/roller combination, DURALUBE chain has lubricant drawn in under vacuum. Released in service, this lubricant provides supplemental lubrication to the pin/bushing joint between regularly scheduled maintenance. Wear life of DURALUBE chain can be up to 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 on specific conditions, Ring Leader chain can provide up to ten times the wear life of standard chain.

Operations in 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. Contaminants can even get inside the chain, actually damaging the surface of pins and bushings. The same design features that allow Ring Leader chain to keep lubrication in also keep contaminants out, making Ring Leader a great choice for applications where chains are exposed to external contaminants.

Diamond EHT Pins

Diamond EHT (Enhance Hardening Treatment) pins have a unique case that maintains the pin hardness in hot, high speed, or abrasive applications. EHT is not a coating, but rather an enhancement to the case hardening of the pin itself. In contrast to platings, EHT pins more closely and consistently match the hardness of the bushings – enabling superior wear performance in difficult conditions without adverse wear in ambient environments.
