Airtac MTF Mini Cylinder MTF25X30CA
The AirTAC Airtac MTF Mini Cylinder MTF25X30CA is a genuine single acting, pull (spring return) JIS-standard round-body mini air cylinder with a Ø25mm bore and 30mm stroke, 1/8" air ports and a SUS304 stainless-steel barrel for mildly corrosive environments. For the same bore and stroke it is shorter than an ISO 6432 cylinder, saving mounting space.

About the Airtac MTF Mini Cylinder MTF25X30CA
Generating 153.6 N of pull at 0.5 MPa (236 N at 0.7 MPa), this JIS-standard round-body mini cylinder is built for spring-open, air-close tasks. The internal spring constantly holds the rod extended, while supplying air to the 1/8" port retracts it. Because it loses air pressure safely to the extended position, it is perfect for fail-safe opening mechanisms. The SUS304 stainless barrel and riveted aluminium covers resist mild washdown, and the body is shorter than an ISO 6432 unit of the same bore and stroke.
This CA back-cover variant provides a rear pivot mount for articulated motion. It uses fixed TPU bumper pads for end-of-stroke deceleration across its 30 mm travel, operating at 50-800 mm/s. As a standard SKU without the -S magnet option, it cannot accept CMSG, DMSG, or EMSG position sensors. Based on the 153.6 N figure, the safe working load is roughly 92 N, translating to a vertical lift capacity of about 7.8 kg with a 2:1 safety margin.

| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 153.6 N |

Where the Airtac MTF Mini Cylinder MTF25X30CA Is Used
Tension Release Mechanism
Holds a tensioned belt or cable extended via spring force, using the 153.6 N air pull to retract and slacken the line during machine cycles.
Fail-Safe Door Opening
Keeps an access hatch pushed open by the spring; air pressure retracts the rod to pull the hatch closed, ensuring it defaults to open on air loss.
Clamp Retraction
Uses the 30 mm stroke to pull a holding clamp out of the way, allowing the spring to push the clamp into the ready position when air is removed.
Is the Airtac MTF Mini Cylinder MTF25X30CA the Right Cylinder?
When sizing this 25 mm bore, compare it both ways: step down to the MTF20 for 93.4 N @0.5 MPa, or step up to the MTF32 for 266.8 N @0.5 MPa. Choose this single-acting pull model when your mechanism must default to the extended position upon air loss, such as a tensioning or clamping release. Remember the 0.2 MPa pressure floor required to overcome the spring force. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion, with this specific CA cover adding a rear pivot point.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/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/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac MTF Mini Cylinder MTF25X30CA FAQ
The single-acting pull force is 153.6 N at 0.5 MPa and 236 N at 0.7 MPa, already net of the spring. It requires a minimum operating pressure of 0.2 MPa to overcome the spring and retract the rod.
No, this specific SKU lacks the internal magnet, so CMSG, DMSG, or EMSG switches cannot be used. You would need the -S variant for sensing. The spring always extends the rod to rest and cannot hold a mid-stroke load.
