Airtac MTF Mini Cylinder MTF40X15SCA
The AirTAC Airtac MTF Mini Cylinder MTF40X15SCA is a genuine single acting, pull (spring return) JIS-standard round-body mini air cylinder with a Ø40mm bore and 15mm stroke, 1/4" 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 MTF40X15SCA
Delivering a robust 434.8 N of pull force at 0.5 MPa, this AirTAC MTF40X15SCA mini cylinder is engineered for single-acting pull operations. A built-in spring holds the rod in the extended position by default, while supplied air retracts it. Upon any loss of air pressure, the mechanism safely fails back to the extended state, making it perfectly suited for spring-open, air-close tasks. The cylinder features a 40 mm bore, a 16 mm rod, and a 1/4" port.
Built as a JIS-standard round-body unit with a SUS304 stainless barrel and riveted aluminium covers, it offers notable mild corrosion resistance and a shorter mounting envelope than an equivalent ISO 6432 cylinder. End-of-stroke deceleration is handled by fixed TPU bumper pads. For position sensing, the -S suffix equips the piston with a magnet for CMSG, DMSG, or EMSG switches, and the CA back cover provides a pivot mount. Based on the 0.5 MPa rating, the safe working load is roughly 261 N, translating to an effective vertical lift capacity of about 22.2 kg with a 2:1 safety margin.

Where the Airtac MTF Mini Cylinder MTF40X15SCA Is Used
Short-Stroke Tensioning
Utilize the 15 mm stroke and 434.8 N pull force to maintain taut tension on belts or filaments, automatically releasing the load to the extended position if air pressure drops.
Spring-Open Valving
Employ the fail-safe-to-extended behavior to keep process valves securely open by default, using pneumatic retraction to close them only when the system is actively pressurized.
Fail-Safe Workpiece Release
Apply the robust 40 mm bore pulling power to retract a holding pin; the spring ensures the pin re-engages to the extended position, safely locking the fixture during an air loss event.
Is the Airtac MTF Mini Cylinder MTF40X15SCA the Right Cylinder?
When sizing this 40 mm bore unit, evaluate your tension requirements against its 434.8 N pull at 0.5 MPa (rising to 645.8 N at 0.7 MPa). If your load is lighter, stepping down to the MTF32 yields 266.8 N at 0.5 MPa; as the largest available MTF bore, there is no larger single-acting pull option in this series. A minimum operating pressure of 0.2 MPa is required to overcome the internal spring.
Select this specific configuration when you need a compact 15 mm stroke for short pulling or clamping motions. The CA pivot back cover suits angular articulation, and the integrated magnet (-S) allows seamless deployment of CMSG, DMSG, or EMSG sensors for end-position confirmation.
Quick checklist
- ✓ Required force at your working pressure

- ✓ 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 MTF40X15SCA FAQ
This single-acting pull cylinder generates 434.8 N of pull force at 0.5 MPa and 645.8 N at 0.7 MPa. These figures are net of the internal spring. It requires a minimum operating pressure of 0.2 MPa to overcome the spring and retract the rod, with a maximum operating pressure of 1.0 MPa.
The internal spring constantly extends the rod, meaning air is only used to pull it in. On air loss, the rod fails to the fully extended position; it cannot hold an arbitrary mid-stroke load. The -S magnet allows CMSG/DMSG/EMSG sensors to track these end positions, and the SUS304 stainless build handles washdown environments.
