European series roller chains

The roller chains of the European series are built according to ISO/R 606-1982 standards that, because of the homogeneity of the adopted standards, can also be called ISO, British Standard (BS) or DIN.
The European Series is the most used in Europe for applications in power transmission and is widely used in most machines built in Europe with power installations from 0.1 kW to 1,000 kW and speed of the sprocket from 500 rpm to 5,000 rpm , with specific cases of rotation speed allowed up to 8,000 rpm for use with 1, 2, 3 and 4 rows of rollers.
