By providing the best roller chain possible, Diamond Chain Company provides its customers with unparalleled expertise in drive systems and design, industry-leading wear and fatigue performance, and superior return-on-investment by reducing its customers' total cost-of-ownership through reliability, long service life, and consistent performance of Diamond® products.

Founded in 1890 in Indianapolis, Indiana, Diamond Chain Company's founders took the diamond as their trademark because it symbolized strength, perfection and served as a constant reminder of the company's commitment to producing the best quality products possible. Throughout its history, Diamond Chain Company's products have been integral part of many notable events: Wright Brothers' first flying machine, Henry Ford's first automobile, and numerous motorsport champions.

Today, Diamond Chain Company is the leading supplier of high performance roller chains for global power transmission markets serving a diverse range of industries such as oil & gas, industrial automation, agriculture equipment, aerospace & defense, and construction equipment. Diamond chains are exclusively relied upon in mission critical drive systems, and the Diamond brand is synonymous with high performance, high quality, and the highest return-on-investment.

In today's global environment, Diamond Chain Company, while focusing on the increased use of innovative technology, still operates under the same solution-oriented, customer-focused philosophy it was founded on. Diamond Chain Company provides customers with end-to-end services such as application engineering support, customized drive system designs, made-to-order specialty chains, and in-field technical support and analysis.
