Metric Roller Chain

For equipment engineered and designed in European markets with conformity with International Standards Organization's standards ISO 606, British standards BS228, or German standards DIN 8187, we offer a broad selection of metric roller chains. The difference between the metric roller chains and chains manufactured to ANSI standards is they utilize different measuring units for chain specifications, such as millimeters, kilograms, and meters. Other characteristics, such as quality of the steel alloy, nickel plating, corrosion resistance, and breaking load strength meet or exceed that of the ANSI roller chain standards. Additionally, if you are needing metric roller chian attachments we supply those as well.

Coated Metric Roller Chain

Coated metric chains are available in sizes 03B up to 56B simplex (-1) and duplex (-2). Coated chains are great in pretty much any application unless there is a large amount of chlorine or other similar chemicals present in the application.
