On the surface, roller chain appears to be a simple product. Although there are five basic components to each link, the number of components operating in a finished chain can easily run into the thousands. For example, a 10-foot length of 40 pitch ANSI chain has 1200 parts. Take into consideration the horsepower, high speed, and challenging operating conditions, and the potential for failure is tremendous. That is why Diamond Chain Company engineers each component to exacting standards, and adheres to a rigorous quality control system to ensure we meet or exceed stringent manufacturing specifications. Diamond chains are able to deliver consistent performance because we forge more than 100 years of experience into every part:
1. Bushing Design: Close tolerances on multiple station cold formers, uniform wall thickness, and tight dimensional control.
2. Plate Design: The multi-stage pitch hole process creates maximum bearing area. Comprehensive shot peening coverage ensures maximum fatigue strength.
3. Pin Design: Precision ground to guarantee a consistent fit and smooth operation.
4. Roller Design: Solid roller design and tight dimensional control during fabrication ensure near perfect roundness.
