Diamond-Drives facilities around the world produce hundreds of different chain sizes and styles. The design, production and assembly data for those chain products are shared globally via our centralized database. Every Diamond-Drives designer, process engineer, application engineer, and manufacturing employee draw from the same, common standards.

Having a single, unified set of specifications simplifies the process of evaluating our manufacturing processes. Every plant measures its performance against the same specs, and every machine meets our capability policy for quality and consistency. We check existing production equipment routinely and test each piece of new equipment to verify its ability to manufacture product that meets our specifications.

Our production assets are operated by qualified and capable Diamond-Drives manufacturing associates who are dedicated to delivering consistent quality. We rely on standardized programs to identify and deliver the training needed to ensure that every manufacturing employee knows how to perform all job functions, including those related to maintaining consistent product quality. Diamond-Drives requires employees to stay current over time on changing standards and improved quality procedures.

To live up to our promise of product dimensional consistency, we must first achieve consistency in our measurement systems. Our precision-gauging system employs measurement system analysis to verify accuracy and consistency. This process, in conjunction with our global master calibration system, makes it possible to measure product to an exceptional level of accuracy and consistency.

The global quality standards in place in all of our design and manufacturing facilities ensure that every component, assembled chain and related product purchased by customers is made to a uniform level of quality. These standards are applied in every plant, without exception. We verify adherence through regular audits of our processes, quality systems and finished products. We engineer new parts for OEMs and we use this experience to create strict testing standards that all our products and suppliers meet.

The life and performance customers expect from Diamond® and Drives® chain relies a great deal on the quality of the steel used.

We purchase steel from carefully qualified providers.

They must successfully pass our supplier quality assurance approval process and meet our stringent specifications. When applicable, our scientists conduct metallurgical testing on both the raw materials and the finished chain to verify that the material meets our standards for cleanliness, hardness and depth.

Diamond and Drives brands are registered in many countries around the world. Only genuine Diamond and Drives products earn the right to feature our brand. When we acquire or expand production to a new Diamond-Drives manufacturing facility, we only mark the product with the Diamond or Drives name after we thoroughly test and inspect all products from the new plant. Each plant must provide proof that its products meet Diamond-Drives global quality standards before those products earn the Diamond or Drives name.

Customers know that only products able to meet Diamond-Drives promise of performance and quality bear the Diamond or Drives name.

Maintaining our level of dedication to quality and consistency requires a significant investment. However, the added expense to protect the quality and trusted value of the Diamond-Drives product portfolio is more than repaid in the higher level of confidence the buyer has that Diamond and Drives chain will provide outstanding performance, reliable operation and long life – traits that bargain chain cannot guarantee.

Our most valued asset is our brand. 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.
