Those designed for transferring power in machines have links designed to mesh with the teeth of the sprockets of the machine, and are flexible in only one dimension. They are known as Roller chains, though there are also non-roller chains such as block chain.
Chains start with the high-performance base materials to ensure increased wear life. We use various grades of steel, heat-treated to precise specifications and assembled with accurate press-fits to withstand the requirements of today's powerful, high-production equipment. Protect your investment in equipment and your operation with Engineering Class Chains.
Those designed for lifting, such as when used with a hoist; for pulling; or for securing, such as with a bicycle lock, have links that are torus shaped, which makes the chain flexible in two dimensions (The fixed third dimension being a chain's length.)
