When selecting sprocket specifications

It is necessary to select a sprocket specification that corresponds to the customer's operating environment and the chain specification used.

Dedicated sprockets are required for surface treated Drive chain NP Series.

Please consult us for details.

Galvanic corrosion may occur when this chain is used with stainless steel sprockets, promoting premature roller wear.
