Wippermann offers suitable sprockets made of C 45 with a hub on one side for hollow pin chains type 01650. Pre-drilled sprockets with 7, 12, 15 and 18 teeth are available ex stock.
Sprockets for hollow pin chains type 01650 are manufactured “ready-to-install” on request (with custom bore, grooves etc.).
For all special sprockets made to specifications we are happy to offer feasibility studies and an individual quotation on request.
