Wear resistance

The wear caused by the rubbing of the joints leads to an elongation of the chain .
The wear depends so basically by the pressure exerted on the surface of the joints and lubrication.

Normally you assess the state of wear of the chains depending on the type of chain :

- Chains farm according to ISO 487 the length must be equal to the nominal with a deviation limit of 0 / 0, 3% ;
- Lifting chains Fleyer type according to ISO 4347 the length must be equal to the nominal with a deviation limit of 0 / 0, 25 % ;
- Chains light transport chains derived from the transmission length must be equal to nominal value with a deviation limit of 0 / 0, 3% ;
- Chains heavy transport according to ISO 1977, the length must be equal to the nominal with a deviation limit of 0 / 0, 25 % ;
- Chains transmission according to ISO 606, 1275, 1395 the length must be equal to the nominal limit with an offset of 0/ 0, 15 % .
