Choosing a Gas Spring: Factors That Matter
Beyond the technical specifications of gas springs like size and force, what else should be considered when choosing a gas spring?
Did you know that in the average modern car there are about 30,000 individual parts? The engine itself contains thousands of tiny internal pieces.
For a car to run efficiently and reliably, each of these parts must work together- if just one of these parts fails, then it can affect the overall car quality and performance.
The same goes for any functioning machinery- which is why choosing reliable components (especially for the most critical components) is essential in the outcome of the machine’s quality and function.
Broadly speaking, gas springs are often considered a critical component in their force and motion control applications. Slight deviations of inconsistent force can cause major issues.
When choosing a critical component like gas springs, there are several factors that need to be considered outside the usual size and force specifications.
Consistent force, reliable operation, process stability, safety, and dependable support can all influence the performance—and ultimately the production process around it.
Gas spring quality is about more than achieving a long service life. Its value can be realized from the very first stroke.
So, beyond the basic specifications, what should you consider when choosing a gas spring?
1. Consistent Reliability from the First Stroke
Regardless of program length, reliability matters in order to produce quality consistently.
When evaluating a gas spring, consider:
- Consistent & reliable performance
- Reduced maintenance requirements
- Predictable force and production outcomes
- Stable tooling performance
- Consistent part quality
- Proven reliability in demanding applications
- Dependable operation as production volumes change
- Confidence in meeting production schedules and delivery commitments
Reliability isn't only about avoiding a failure after a million strokes. It's about avoiding problems from the first stroke onward.
A reliable component helps reduce uncertainty in the tool and gives engineering, maintenance, and production teams greater confidence in the process.

2. Safety and Quality Standards
Gas springs operate under high internal pressure, making safety and manufacturing quality critical considerations.
Beyond the product specifications:
- How thoroughly are the products tested?
- Are manufacturing and quality processes controlled and documented?
- Is product performance validated?
- Is manufacturing traceable?
- What safety features have been engineered into the product?
- What resources are available to support safe installation, operation, and maintenance?
This is where quality becomes more than a lifespan discussion.
Safety Features

3. Service and Support
Even the best component operates as part of a larger global system, which makes the local support behind it important.
Before choosing a gas spring supplier, ask:
- Is knowledgeable technical support available locally when needed?
- Can the supplier provide application guidance?
- Are replacement units readily available?
- Is support available in the regions where you manufacture?
- Can the supplier provide training and help improve safe product use?
For multinational OEMs, Tier suppliers, and toolmakers operating across multiple regions, this can be especially important.
Access to knowledgeable support can help teams solve application challenges, make informed product selections, and respond more effectively when production requirements change.
The relationship with your supplier therefore shouldn't end when the component arrives.
Services, Support, & Training
When you use KALLER, you are backed by a global support network with decades of accumulated application expertise, comprehensive training both online and in person, and a broad range of services designed to help you get the most from your solution.

4. Total Cost of Ownership
Purchase price is one of the easiest factors to compare when sourcing components.
Purchasing cheap components can ultimately lead to paying the price of a poor reputation once the quality of the product suffers.
Once a gas spring is installed, it becomes part of a larger production system. Unexpected tool modifications, maintenance, component replacements, or downtime can affect far more than the cost of the component itself.
The true cost can also include:
- Overtime & Maintenance labor
- Unplanned downtime
- Replacement inventory
- Emergency shipments
- Production delays
- Quality issues
- Tooling interruptions
- Safety and Liability issues
A cheap gas spring may initially look attractive from a procurement perspective. But if it requires additional maintenance, creates process variation, or contributes to production interruptions, the total cost can quickly change.
The cheapest gas spring to buy is not always the least expensive gas spring to own.
Evaluating Total Cost of Ownership gives purchasing and engineering teams a more complete basis for comparing alternatives.
