How to Select a Shock Absorber (KOBA & IZMAC)
A wrong shock absorber means early failure, noise, product damage or unnecessary cost. This guide summarizes the basics used when starting model selection in KOBA and IZMAC families.

1) Required data
- Kinetic energy (Nm) or mass + velocity
- Impact speed (m/s)
- Cycles per hour
- Ambient temperature and environment
- Mounting style
- Stroke and space limits
If you prefer, you can use our model selection tool to continue with these inputs.
2) Adjustable vs self-compensating
Adjustable (e.g. KOBA KMA/KHA, IZMAC IAA)
Best when load/speed varies and fine-tuning is needed.
Self-compensating (e.g. KOBA KMS, IZMAC IMS)
Good for defined operating windows without a tuning screw.
3) Series map
- KOBA KMA / KMS — mini/compact
- KOBA KHA / KSA — mid/large adjustable
- KOBA KHG / KHS / KCSC — heavy-duty / crane buffers
- IZMAC IAA / IMS / IHA / ISA — mini to heavy
- IZMAC IHG / ICA — gas-oil and stacker crane buffers

4) Common mistakes
- Sizing by thread/stroke only
- Ignoring heat/life at high cycle rates
- Off-axis impact
- Treating catalog peaks as continuous duty
5) What to send for a quote
