Airtac MTF Mini Cylinder MTF25X40SCM
The AirTAC Airtac MTF Mini Cylinder MTF25X40SCM is a genuine single acting, pull (spring return) JIS-standard round-body mini air cylinder with a Ø25mm bore and 40mm 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 MTF25X40SCM
Generating a net pull of 153.6 N at 0.5 MPa, this single-acting spring-return mini cylinder uses air to retract the rod and an internal spring to push it back out. The MTF25X40SCM features a JIS-standard round-body construction with a SUS304 stainless barrel and riveted aluminium covers, offering a shorter mounting envelope than a comparable ISO 6432 unit. It includes a CM round-end rear cover and a built-in magnet (-S) for position sensing.
Because the spring holds the piston normally extended, the cylinder fails safely to the open position upon air loss, making it ideal for spring-open/air-close tasks. The 1/8" port and Ø10 mm rod with an M10x1.25 male thread provide robust connectivity. With a 153.6 N pull at 0.5 MPa, the computed safe working load is roughly 92 N, yielding a vertical lift capacity of about 7.8 kg with a 2:1 safety margin. End-of-stroke deceleration is handled by fixed TPU bumper pads rather than an adjustable cushion.

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

Where the Airtac MTF Mini Cylinder MTF25X40SCM Is Used
Tensioning Systems
Pulls webbing or wire with a 153.6 N force at 0.5 MPa, automatically relaxing tension when air is removed.
Fail-Safe Lids
Holds covers open via spring force; air retraction pulls the lid closed securely during operation.
Part Retraction
Withdraws 7.8 kg tooling components out of the work zone using compressed air, relying on the spring to reset.
Is the Airtac MTF Mini Cylinder MTF25X40SCM the Right Cylinder?
When sizing this 25 mm bore, compare its 153.6 N pull force at 0.5 MPa against adjacent bores: step down to the MTF20 for 93.4 N, or move up to the MTF32 for 266.8 N. Choose this model for tensioning, clamping, or fail-safe-open mechanisms where air retracts the load and the spring ensures a predictable extended rest state. Maintain at least 0.2 MPa operating pressure to overcome the internal spring. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion brackets, while the included -S magnet supports CMSG, DMSG, and EMSG sensors.
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 MTF25X40SCM FAQ
It provides a net pull force of 153.6 N at 0.5 MPa and 236 N at 0.7 MPa. The cylinder requires a minimum operating pressure of 0.2 MPa to overcome the return spring and retract the rod.
The internal spring constantly extends the rod, meaning the cylinder defaults to the extended position on air loss. The -S variant includes a piston magnet for use with CMSG, DMSG, or EMSG switches, and the SUS304 stainless barrel resists mild corrosion.
