Quality & Engineering

Roller-chain quality is built through material control, formed components, heat treatment, surface engineering, assembly and inspection. Useful validation includes dimensional measurement, tensile testing, fatigue evaluation, wear testing and surface-condition measurement.

Application validation

For DHA configurations, the most useful questions concern dust type, particle hardness, load spectrum, speed, lubricant delivery and sprocket condition. Those inputs determine whether a treated-pin chain, sealed chain, corrosion-resistant chain or another architecture is appropriate.
