Self-tooth-forming| P.I.V. chains
self tooth forming PIV chains PIV Chains (positive infinitely variable chains) comply with the ZBJ18003-89 standard for the application of chain driven gear boxes. These chains are used for the roller type infinite speed variators of the textile industry, on automotive variable speed drives as well as in variable pitch V grooves.
