Nothing Outlasts a Diamond® by Timken

Longer lasting chain results in less downtime and better return on investment

High Strength Series

It is evident that a Diamond Series roller chain is different the moment it is removed from the box. The uniquely beveled linkplates (sizes 60-160) and proprietary lubrication are easily identified, but the real value of these features - and all the features that comprise “The Diamond Difference”  are not just seen but experienced. Diamond Series chain has been verified to deliver superior wear life vs. the competition. 

Built to ASME / ANSI B29.1 standards for dimensions, interoperability, and sprocket fit.

Same as Heavy series but with medium carbon through-hardened pins for a higher tensile strength, working load, and fatigue strength (but lower wear performance) vs. Heavy Series chain. For use in high load, lifting, or pulsating applications.
