What you need to know about ISO (BS) roller chains?
A significant part of the roller chains used in Europe are manufactured according to ISO R606. This standard is originally based on the English standard BS228, which is why ISO chains are often referred to as ISO (BS) roller chains. Based on their structure, roller chains consist of a pin, roller, connecting plate (sponge cake). The material and design of the parts determine the quality of the roller chains. However, the value specified in the standard is usually met by roller chains of any manufacturer. In everyday use, reinforced chains are usually not required. The ISO (BS) standard does not specify a standard for reinforced designs. Reinforced ISO roller chains, which may be commercially available, are manufactured according to the individual ideas of manufacturers. (From reinforced chains, ANSI H standard reinforced versions are also widespread in Europe.)
