Diamond roller chain
Diamond Chain drive
Diamond Chain's Diamond Series is an American-made product that is engineered, manufactured, and assembled in Indianapolis, Indiana since 1890. Diamond Chain’s unrivaled experience, unsurpassed quality, and unparalleled performance are the keys to building an industry-leading roller chain, because when it comes to performance, nothing outlasts a Diamond.
What gives Diamond Chain its superior chain performance?
Diamond Chain uses raw materials that meet exacting standards for metal grade, mechanical properties, carbon, and alloy content to ensure the minimization 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.
While roller chain may appear to be a simple product, the number of components in a 3-m (10-ft) section of 40-pitch chain totals 1200 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.
- Plates: inner and outer plates go through a four-stage pitch-hole process. A multi-stage process is utilized to create a maximum bearing area that is straight, smooth, and burr free.
- Pins: precision grinding ensures consistent fit and smooth travel.
- Rollers: seamless roller design and dimensional control allows for extrusion with near-perfect roundness.
- Bushings: dimensional control enables bushings to be extruded with uniform wall thickness and concentricity for smooth travel. Near-perfect roundness increases the effective bearing area for the pin.
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.
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.
Diamond understands the importance of proper lubrication and its impact on a chain's wear life. Diamond Chain uses both 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.
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.
Diamond Chain comes standard on all 9 Series Round Balers.
The 449 Round Baler has 60 Diamond chain for its upper drive roll chain and 60H for its lower drive roll chain.
The 459E, 459, 459 Silage Special, 559, and 559 Silage Special have 60H Diamond Chains for their upper and lower drive roll chains.
The 469, 469 Silage Special, 569, and 569 Silage Special have 80 Diamond Chains for their upper and lower drive roll chains.
The 469 Premium and 569 Premium Round Balers have 80H Diamond Chain for their upper and lower drive roll chains.
