Maximum Working Stroke

The nominal stroke (defined as S in the catalogue) may be utilised to 100% in all KALLER gas springs.

However the recommendation is not to use the full stroke in normal operation. This is to prevent the gas spring from being “over-stroked” as a result of changes to the tool or mis-happenings in the tool.

We do not recommend the last 5 mm or 10% of the nominal stroke length to be utilised. Using more than 100% of the nominal stroke is not allowed.
