How to Choose Between Adjustable and Non-Adjustable Shock Absorbers
A practical selection note for deciding whether an adjustable or self-compensating absorber is the better starting point.
Direct answer
Use an adjustable shock absorber when the load, speed or drive force changes enough that damping needs to be tuned on the machine. Use a non-adjustable or self-compensating absorber when the stop condition is repeatable and the goal is tamper-resistant operation with less commissioning effort.

Required inputs
Review steps
- 1
Check how stable the application is
A repeated end stop with narrow mass and velocity variation usually favors a non-adjustable absorber; frequent product or speed changes may justify adjustment.
- 2
Decide whether tuning is useful or risky
Adjustment helps during commissioning, but it also creates a setting that can be changed later. Use it where controlled tuning is expected.
- 3
Confirm energy, stroke and duty rating
The adjustable/non-adjustable decision does not replace sizing. The selected model still needs enough energy per cycle, energy per hour, stroke and force capacity.
Common mistakes
- Choosing an adjustable model only because it feels more flexible, even when the application is fixed and repeatable.
- Ignoring who will control the adjustment setting after installation.
- Comparing only thread size and stroke without checking energy and hourly duty.
Technical notes
- Adjustable families are useful where damping force needs to be tuned. Non-adjustable/self-compensating families are better suited to stable repeated stop conditions.
