Roller chain bas been produced from high quality materials (both plastics and steels)  using the latest manufacturing procedures. These factors combine to produce superior quality roller chain that offers high tensile strength, 30% less elongation due to wear and a 40% longer service life in comparison with standard roller chain.   During the manufacturing process, rollers and link plates are fortified against fatigue by shot peening and link plate holes are double punched to improve component fit and increase fatigue strength. All General roller chain is also continuously pre-loaded following final assembly to ensure the correct seating of the components and to reduce initial chain elongation.   Extensive range We supply the full range of BS and ANSI roller chains from stock in standard or cut lengths as well as sprockets and other associated machined products. We even supply 1/8" pitch chain, which is the world's smallest transmission chain, for the medical and micro-engineering industries. Our comprehensive warehouse also holds a wide range of special application and self-lubricating chains for especially agressive environments.
