Length measurement of chains
In order to ensure quality and performance of a chain, a correct length measurement is crucial.
General information according to ISO 606
- Time of measurement:
Measurement is carried out after preloading, but in an unlubricated condition. - Standard measuring lengths:
- 610 mm for ISO chain numbers 04C to 12B (incl. 081 to 085)
- 1220 mm for ISO chain numbers 16A to 72B
- Measuring conditions:
- The entire chain length must be supported during measurement.
- The measuring force is applied according to the table.
Tolerances
- Standard chains: +0.15% of nominal length
- Chains with attachments +0.3% of nominal length
- Paired chain operation may require tighter tolerances.
Tip: Tighter tolerances are vital for applications in which two chains run synchronously.
Additional information
For chains not specified in the tables, the measuring force to be applied is 1% of the chain breaking force.
