Nothing Outlasts a Diamond® by Timken

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

Heavy Duty Series - Single Strand and Multiple Strand

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.

Heavy Series chain takes the Standard Series and adds thicker linkplates for increased fatigue resistance in applications involving heavy shock loads, multiple start/stops, or reversing. Heavy series chain utilize linkplates with the thickness of the next larger size chain
