Electric vs pneumatic grippers: a practical guide for integrators
Electric and pneumatic grippers solve the same job very differently. This guide compares them on control, cost, flexibility, safety and maintenance so you can choose with confidence.
Choosing between electric and pneumatic gripping is one of the most consequential decisions in a robot cell. Both close two jaws on a part — but how they do it shapes flexibility, running cost and safety for the life of the cell.
Side-by-side comparison
| Criterion | Pneumatic gripper | Electric (servo) gripper |
|---|---|---|
| Force control | Usually fixed (one pressure) | Programmable, multiple levels |
| Position control | Two states (open/closed) | Any position within stroke |
| Stroke / flexibility | Narrow without jaw change | Wide range, one configuration |
| Running cost | Continuous compressed-air cost | Electrical only — no air |
| Maintenance | Seals, hoses, FRL units | Minimal; no pneumatics |
| Data / feedback | Limited | Position & part-presence feedback |
| Power-loss behaviour | May release without pressure | Can hold mechanically (Servo-Flex) |
| Best for | Simple, fixed, high-volume tasks | High-mix, flexible, data-driven cells |
Where each one wins
Pneumatic still makes sense for very simple, single-part, high-volume tasks where air is already plentiful and flexibility is not needed.
Electric wins almost everywhere else — and especially in high-mix production, cobot cells, and any application where removing compressed air, gaining flexibility, or holding the part safely on power loss matters.
The hidden cost of air
Compressed air is one of the most expensive utilities in a factory once leaks and generation are counted. Removing it does not just cut cost — it removes hoses from the arm and a whole class of maintenance.
The takeaway
If your cell handles more than one part, values uptime, or runs collaboratively, a servo-electric gripper is usually the better long-term choice. See how Servo-Flex applies this in the technology page, or explore the Flexi 100 and Flexi 150.
