About the Airtac MSI Single Acting Stainless Steel Mini Cylinder MSI8X25CA
Generating 18.6 N of push force at 0.5 MPa, this stainless-steel round-body mini cylinder uses compressed air to extend the rod and an internal mechanical spring to retract it. Because it is a single-acting push type, you only need one M5x0.8 air line to operate it, saving plumbing and air consumption. If air pressure drops below the 0.2 MPa minimum required to overcome the spring, the rod automatically returns to its retracted rest state.
Built to ISO 6432 mounting interface dimensions, the Ø8 mm barrel and Ø4 mm piston rod feature a riveted construction that resists mild corrosion and washdown environments. The fixed TPU bumper pads cushion the stroke ends without acting as a mid-stroke load lock. Based on the 18.6 N push figure, it handles a safe working load of roughly 11 N, making it suitable for clamping or lifting about 0.9 kg vertically with a 2:1 safety margin. Note this specific SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors.

Where the Airtac MSI Single Acting Stainless Steel Mini Cylinder MSI8X25CA Is Used
Small Part Clamping
Provides 18.6 N of extend force to secure light plastic or cardboard components during machining, with the spring ensuring automatic release if air fails.
Package Diverter Gate
Acts as a lightweight push gate to redirect small items on a conveyor line, using the fail-safe retract to clear the path on air loss.
Pin Ejection
Extends a Ø4 mm rod to push finished pins out of a die, lifting up to 0.9 kg against gravity before the internal spring retracts the tooling.
Is the Airtac MSI Single Acting Stainless Steel Mini Cylinder MSI8X25CA the Right Cylinder?
When sizing this single-acting push cylinder, evaluate your required extend force against the 18.6 N available at 0.5 MPa (or 28.7 N at 0.7 MPa). As this is the smallest bore in the MSI family, there is no smaller option; if your load exceeds the safe working capacity of roughly 11 N, step up to the Ø10 bore, which provides 29.5 N at 0.5 MPa. Remember that the internal return spring requires at least 0.2 MPa of input pressure to begin extending the rod.
The 25 mm stroke sits well within the 50 mm standard spring limit for Ø8 bores, ensuring off-the-shelf availability. This model features a CA rear pivot cover for clevis mounting, and because it lacks the -S magnet suffix, position sensing is not supported on this unit.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.2 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check Use correct back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac MSI Single Acting Stainless Steel Mini Cylinder MSI8X25CA FAQ
It delivers a push force of 18.6 N at 0.5 MPa and 28.7 N at 0.7 MPa. Because it is single-acting with a spring return, you must supply at least 0.2 MPa to overcome the spring and extend the rod; when air is released, the spring drives the rod back to the retracted rest position.
No, this specific SKU does not have a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors. You would need the -S variant for position sensing. It features a CA pivot back cover, an M5x0.8 port, and a stainless-steel build for mild corrosion resistance.
