The Timken Company acquired Diamond Chain Company, a supplier of high-performance roller chains for industrial markets, from Amsted Industries. Indianapolis, Ind.-based Diamond Chain has manufacturing operations in the U.S. and China and employs approximately 370 people. The company uses enhanced heat-treatment processes that help pins maintain rigidity in the most challenging environments. Diamond Chain also utilizes laser fabrication to drastically cut manufacturing times for custom-made chain attachments.

The acquisition increases Timken’s presence in the global roller-chain market by adding a product line used in a range of applications. It also gives Timken additional opportunities to deliver more value for customers in the industrial distribution, material-handling, agriculture and construction industries.
