American roller chains according to ISO 606

for use in mechanical and plant engineering

Roller chains conforming to ISO 606 (formerly DIN 8187) are widely used in mechanical and plant engineering. They are used not only as drive and transmission chains, but also as drive-stock, lifting, and conveyor chains, as well as in special designs with various attachments for transport and conveying purposes.
