For products engineered and designed in European marketplaces with metric roller chain conformity with Worldwide Standards Organization’s requirements ISO 606, British criteria BS228, or German standards DIN 8187, we offer a broad collection of metric roller chains. The difference between the metric roller chains and chains manufactured to ANSI standards is they make use of different measuring units for chain specs, such as for example millimeters, kilograms, and meters. Other characteristics, such as quality of the metal alloy, nickel plating, corrosion resistance, and breaking load power meet or exceed that of the ANSI roller chain specifications. Additionally, in case you are needing metric roller chian attachments we supply those aswell.
