Duralube® LIVE Chain

Diamond® Duralube® LIVE chain is a reduced-maintenance product in which lubricant is infused into the bushing and released during service, providing supplemental lubrication to the pin/bushing joint.

Reduced maintenance roller chains are intended for applications where regular lubrication is not possible or practical. The life of these chains is significantly greater than a traditional chain that only has its initial lubrication. In all cases, life of reduced maintenance chain can be extended even further if regular lubrication is possible.

Features & Benefits

  • Materials

    The Diamond Difference begins with raw materials that meet exacting standards for metal grade, mechanical properties, carbon and alloy content to ensure minimization of impurities that impact tensile and fatigue strength.

  • Fabrication

    Diamond designs each component to exacting dimensional standards for optimal performance. So, what makes this chain “reduced maintenance?” Duralube® LIVE chain features a powdered metal bushing infused with lubricant, providing supplemental lubrication to the pin/bushing joint.

  • Heat Treatment

    Strict control of atmosphere, time and temperature optimize the material properties – increasing strength, durability and wear resistance.

  • Shot Peening

    Proprietary shot peening equipment was developed specifically to ensure consistent intensity and coverage of components. Shot peening adds a layer of compressive stress that helps components resist fatigue failure when exposed to repeated high loads.

  • Lubrication

    We use a proprietary lubrication process on all lubricated chains for enhanced corrosion protection and extended wear life. Along with the initial factory lubrication, Duralube LIVE has a bushing infused with lubricant. An H1 food grade lubricant can also be used for incidental contact.

  • Preloading

    Following assembly, all chains are preloaded to firmly seat the pins and bushings. This is to reduce initial run-in and extend the wear life of the chain.
