Coupling Chain

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.

Diamond designs each component to exacting dimensional standards for optimal performance. Precision ground pins, seamless rollers and extruded solid bushings work in concert with linkplates created using a proprietary multi-stage process to maximize the bearing area and thus enable the superior performance of Diamond^® Coupling chain. This double-strand chain is press-fit and constructed to exact length, along with a single coupling bolt to facilitate easier assembly or disassembly.

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

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.

We use a proprietary lubrication process on all lubricated chains for enhanced corrosion protection and extended wear life.

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.
