Airtac MTF Mini Cylinder MTF25X30SCA
The AirTAC Airtac MTF Mini Cylinder MTF25X30SCA 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 MTF25X30SCA
Delivering 153.6 N of net pull force at 0.5 MPa, this AirTAC MTF25X30SCA mini cylinder is built for spring-open, air-close tasks. It is a JIS-standard round-body unit featuring a SUS304 stainless barrel and riveted aluminium covers. The internal spring constantly pushes the rod out, while supplying air to the 1/8 inch port retracts it. If air pressure drops, the spring safely drives the rod back to the extended rest position.
Because of its riveted construction, the body is shorter than an ISO 6432 cylinder of the same bore and stroke, saving valuable machine space. The fixed TPU bumper pads absorb end-of-stroke impacts across the 50-800 mm/s speed range. For position sensing, the built-in -S magnet supports CMSG, DMSG, or EMSG switches. Based on the 0.5 MPa rating, the safe working load is roughly 92 N, which means it can vertically lift or hold about 7.8 kg with a 2:1 safety margin.

Where the Airtac MTF Mini Cylinder MTF25X30SCA Is Used
Tension Control
Pulls a belt or filament tight with 153.6 N force at 0.5 MPa, releasing tension only when air is applied.
Fail-Safe Gate
Holds a guard door open pneumatically; the spring automatically extends the rod to lock it shut upon air loss.
Light Lift Retract
Lifts a 7.8 kg fixture safely with a 2:1 margin, using air to lower the load and the spring to return it.
Is the Airtac MTF Mini Cylinder MTF25X30SCA the Right Cylinder?
Choose this 25 mm bore if you need more power than the MTF20 (93.4 N at 0.5 MPa) but less bulk than the MTF32 (266.8 N at 0.5 MPa). It fits perfectly for tensioning or clamping where the rod must stay extended by default and air pulls it back. You must supply at least 0.2 MPa to overcome the return spring, up to a maximum of 1.0 MPa. The CA rear pivot cover pairs with LB foot, FA flange, SDB pivot, or TC trunnion mounts for flexible installation.
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 MTF25X30SCA FAQ
It provides a net pull force of 153.6 N at 0.5 MPa and 236 N at 0.7 MPa. The operating pressure range is 0.2-1.0 MPa, and a minimum of 0.2 MPa is required to overcome the internal spring.
The spring constantly extends the rod; air pressure retracts it, meaning it fails to the extended position on air loss. The -S option includes a piston magnet for CMSG, DMSG, or EMSG sensors, and the SUS304 stainless build resists mild corrosion.
