Selection and Coupling

The length of a chain can be measured in order to control its degree of precision and verify that it corresponds to the reference standards. This measurement is carried out on assembled and non-lubricated chains and differs for each type as follows:

• Short-pitch precision chains: the reference standard is ISO606 which allows a deviation from the nominal value up to 0, + 0.15%;
• Long-pitch precision chains: the reference standard is ISO1275 which allows a deviation from the nominal value up to 0, + 0.15%;
• Heavy-duty conveyor chains: the reference standard is ISO1977 which allows a deviation from the nominal value up to 0, + 0.25%;
• Agricultural chains: the reference standard is ISO487 which allows a deviation from the nominal value up to 0, + 0.3%.

Coupling is a fundamental and necessary operation for all applications in which two or more chains will have to work side by side. For their correct use, they must be selected to ensure a higher level of precision. This operation is carried out internally by us with modular traction benches which, through optical fiber and a probe, detect the length of each chain branch with a precision of 0.01mm. Each individual branch, divided according to the tolerance range established with the customer, is labeled to allow for correct and intuitive final assembly.
