2.3.6 Relative Differences in Chain's Total Length
If you want to achieve a precise positioning of more than two chain lines to be used in parallel, you can order "matched and tagged" chain. Generally, if the conveyor chains are made in the same lots, the relative differences in length will vary only slightly. Table 2.5 shows the amount of variation for several types of chain chosen at random from the same production run.
If your specific application requires less variation than those listed in Table 2.5, consider matched and tagged chains as an effective solution.
|Center Distance||Matched Tolerance|
|Less than 7 m||Less than 3 mm|
|7~15 m||Less than 4 mm|
|15~22 m||Less than 5 mm|
