Airtac MTF Mini Cylinder MTF40X75SU
The AirTAC Airtac MTF Mini Cylinder MTF40X75SU is a genuine single acting, pull (spring return) JIS-standard round-body mini air cylinder with a Ø40mm bore and 75mm 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 MTF40X75SU
Delivering 434.8 N of net pull at 0.5 MPa (645.8 N at 0.7 MPa), this 40 mm bore cylinder is built for heavy-duty tensioning and air-close tasks. The internal spring constantly pushes the 16 mm rod outward, meaning a loss of compressed air automatically drives the mechanism to its extended, fail-safe state. Because the MTF body is shorter than a comparable ISO 6432 unit, it saves valuable machine space while the SUS304 stainless barrel and riveted aluminium covers shrug off mild washdown environments.
Featuring a 1/4" port and an M14x1.5 male rod thread, the unit retracts the load only when pressurized above the 0.2 MPa floor. For practical sizing, the 434.8 N @0.5 MPa rating translates to a safe working load of roughly 261 N, or a vertical lift capacity of about 22.2 kg when applying a 2:1 safety margin. This specific SKU includes a U flat-end back cover and a built-in magnet (-S) for position sensing.

Where the Airtac MTF Mini Cylinder MTF40X75SU Is Used
Heavy-Duty Tensioning
Pulls webbing or wire with up to 261 N of safe working force at 0.5 MPa, releasing the tension automatically if the air supply drops.
Fail-Safe Open Valves
Holds a heavy pintle valve open via spring pressure; applying air through the 1/4" port retracts the 16 mm rod to close the valve securely.
Carton Lid Lifting
Uses the 645.8 N pull at 0.7 MPa to snap heavy packaging lids shut, with the spring pushing the lid back open when the air signal ceases.
Is the Airtac MTF Mini Cylinder MTF40X75SU the Right Cylinder?
When sizing this 40 mm bore option, compare it directly against the next size down: the MTF32 provides 266.8 N of pull at 0.5 MPa. If your application requires less force, stepping down to the 32 mm bore saves space, but this 40 mm model is the maximum bore available in the MTF family. Choose this single-acting pull configuration when you need a mechanism to fail to the extended position, such as a spring-open clamp or emergency release.
Ensure your air supply can reliably exceed the 0.2 MPa minimum operating pressure required to overcome the internal spring. Mounting flexibility is provided via LB foot, FA flange, SDB pivot, or TC trunnion brackets. Because this SKU carries the -S suffix, it is fully compatible with CMSG, DMSG, and EMSG electronic or reed switches for precise end-of-stroke detection.
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 MTF40X75SU FAQ
This 40 mm bore cylinder provides a net pull force of 434.8 N at 0.5 MPa and 645.8 N at 0.7 MPa. It requires a minimum operating pressure of 0.2 MPa to overcome the internal return spring and begin retracting the rod.
The spring constantly extends the rod; air pressure pulls it in. On air loss, the rod fails to the extended position, meaning it will not hold a mid-stroke load. The -S suffix denotes a built-in piston magnet for use with CMSG, DMSG, or EMSG sensors.
