* Chain length tolerance ± 0,25 % of unoiled chain under measuring force.
With Heavy Series U chains all plates are mounted with a sliding fit and are also secured with laterally attached riveted washers.
This design guarantees an even load distribution and reduces the bending load of the pin. These chains have been designed to transport heavy loads under harsh conditions. They are particularly suitable for such applications due to their high fatigue strength
