Stroke, Energy and Force: Which Rating Should Be Checked First?
A short engineering sequence for checking absorber ratings without reducing selection to a single catalog number.
Direkte Antwort
Start with available stroke and required stopping energy, then check energy per hour and impact force. A model is only suitable when all of these ratings make sense together; passing a single rating is not enough for a reliable selection.
Fragen, die diese Seite beantwortet
- Which shock absorber rating should be checked first?
- Is stroke or energy more important for shock absorber selection?
- Why can a shock absorber pass one rating and fail another?

Average stopping force
A shorter stopping stroke increases average force for the same absorbed energy, so stroke and force should be reviewed together.

Prüfschritte
- 1
Confirm usable stroke
Check the machine can physically use the absorber stroke without bottoming out or hitting a mechanical stop first.
- 2
Check energy per cycle
Calculate the energy of one impact, including drive force or gravity where relevant.
- 3
Check duty and force
Multiply by cycle rate for hourly energy, then compare estimated stopping force with absorber and machine limits.
Typische Fehler
- Selecting by stroke alone because the product fits the space.
- Checking energy per cycle but ignoring repeated high-frequency operation.
- Choosing a very short stroke and then discovering the frame sees excessive stopping force.
Technische Hinweise
- Product rating tables commonly list stroke, energy per cycle, energy per hour and maximum impact force because these limits must be checked together.
