* Chain length tolerance ± 0,25 % of unoiled chain under measuring force.
Abstract from ISO 4347 – Chains may be assembled with chain parts according to ISO 606. Therefore the actual pitch may deviate from the nominal pitch.
The permissible length deviation refers to the length specification of the manufacturer and is ± 0,25 % under the measuring force.
