Carbon Steel to ISO Standard 606R/ Works Standard

In the past 50 years as more manufacturers have entered the market, Roller Chains have developed into two main categories. Chains that Conform to International renown Standards such ISO or Din or ANSI standards offering continuity in Quality and Specification with the added benefit of interchangeability across brands, and alternatively manufacture’s own Works Standard Chains which may have some dimensions and characteristics the same, but will have some variation from the ISO specification and are therefore not interchangeable.

The key to providing both Product reliability and Customer satisfaction is matching the correct Quality to suit the customers application requirements, hence the company stocks and supplies a combined range of Roller Chains from around the World so that it is independant of any one brand and therefore free to match the Best Quality to suit the application at the most Competitive price.
