    Materials

    The Diamond Chain Company’s proprietary material standards and manufacturing processes form the core of the Diamond® Difference. The Diamond Difference begins with raw materials that meet exacting standards for metal grade, mechanical properties, carbon and alloy content to ensure the minimisation of impurities that impact tensile and fatigue strength

    These proprietary standards enable Diamond Chain components to maintain tighter tolerances throughout the fabrication and assembly process for a finished product with unparalleled quality, performance, and longevity.

    Fabrication

    While roller chain may appear to be a simple product, the number of components in a ten foot section of 40 pitch chain totals 1,200 pieces, each a potential point of failure.

    Diamond Chain designs each component to exacting dimensional standards and has a rigorous quality control system in place to ensure that only qualified pieces reach the final assembly stage.

    1. PLATES: Inner and outer plates go through a four stage pitch hole process. A multi-stage process is utilised to create a maximum bearing area that is straight, smooth, and burr-free.

    2. PINS: Precision grinding ensures consistent fit and smooth travel.

    3. ROLLERS: Seamless roller design and dimensional control allows for extrusion with near perfect roundness.

    4. BUSHINGS: Dimensional control enables bushings to be extruded with uniform wall thickness and concentricity for smooth travel. Near perfect roundness increases the effective bearing are for the pin.

    Heat Treating

    The Diamond Chain Company heat treats components using dedicated carburizing furnaces set to precise temperatures.

    Through strict control of both atmosphere and quench, Diamond Chain components receive maximum carbon penetration for a high carbon surface and low carbon core. The process ensures consistent depth of case hardening increasing strength, durability, and wear resistance.

    Shot Peening

    The Diamond Chain Company uses proprietary shot peening machinery developed and custom made to ensure consistent intensity and coverage of components during the shot peen process.

    This highly controlled process ensures that components receive the same level of treatment for a consistent compressive surface stress that helps to increase fatigue resistance.

    Lubrication

    Diamond understands the importance of proper lubrication and its impact on a chain's wear life. Diamond Chain uses both a proprietary lubrication formula and “hot dip” application process on all lubricated roller chains. The “hot dip” process ensures complete coverage of components while the proprietary lubricant maintains maximum continuing surface retention following the treatment. Special additives in the lubricant further enhance corrosion protection and extend wear life.

     

     

     

     

     

  • Our Preloading Process Open or Close

    Preloading

    The final stage of the manufacturing and assembly process for each Diamond roller chain is the preloading stage. Preloading approximates the recommended maximum loading during usage and is done to firmly seat pins and bushings in place and eliminate any initial elongation that may take place.
