About Diamond-Drives by Timken

Diamond-Drives by Timken is one of the most storied names in precision chain manufacturing, with a heritage stretching back to 1890. Diamond Chain Company got its start as Indianapolis Chain & Stamping Company, manufacturing bicycle chain in Indianapolis, Indiana. The company's founders selected the diamond as their trademark because it symbolized perfection — a standard the brand has lived up to ever since.

Diamond Chain's products were integral in many historical breakthroughs, including the Wright Brothers' first flying machine, Henry Ford's first automobile, and numerous motorsport champion vehicles. That legacy of innovation and reliability is what sets Diamond apart in the power transmission world.

Part of the Timken Family

Diamond® and Drives® are now part of The Timken Company's growing portfolio of engineered bearings and industrial motion products. This union brings together a combined 195 years of advanced engineering knowledge and experience, making Diamond-Drives one of the most technically capable chain suppliers available today.

Diamond-Drives by Timken continues to take the necessary measures to confidently tell customers that the quality of a Diamond or Drives product is the same no matter where in the world it is manufactured or purchased. That consistency is backed by rigorous metallurgical and quality standards: Diamond engineers new parts for OEMs and uses this experience to create strict testing standards that all their products and suppliers must meet.

Precision Engineering in Every Link

What makes a Diamond chain different from the competition comes down to manufacturing precision. Fine attention to detail during the fabrication process gives Diamond roller chains tighter tolerances, precise inner dimensions, and higher fatigue strength — preloaded at up to 50% of the chain's tensile strength to make run-in wear virtually nonexistent.

Diamond-Drives offers a broad line of superior quality precision roller chain, engineered class chain, and augers engineered to push the world's toughest applications. Whether you need a standard Drive Chain for a powersports or motorsport application, or a heavy-duty solution from the Chains lineup for industrial equipment, Diamond has a product engineered for the job.

Support Beyond the Product

If your machine has a challenging demand beyond the scope of a standard Diamond or Drives product, their experts are ready to work with you to provide engineered solutions — bringing extensive technical experience and industry expertise to analyze chain applications and apply practical, real-world insight. Diamond-Drives customers also receive maintenance education and ongoing technical support to ensure their solutions continue to perform.

For anyone who demands reliability and precision in their drivetrain, Diamond-Drives by Timken represents over a century of proven engineering excellence.
