About the Airtac MTI Single Acting Stainless Steel Mini Cylinder MTI40X10SU
Generating a 466.8 N pull force at 0.5 MPa, this AirTAC round-body mini cylinder uses compressed air to retract the rod while an internal spring pushes it back out. Because the spring holds the rod extended at rest, the mechanism naturally fails safe if air pressure drops, keeping gates or hold-downs engaged. The stainless steel barrel and rod resist mild corrosion and washdown environments.
Equipped with a 1/4" port and a 16 mm rod, the unit requires at least 0.2 MPa of input pressure to overcome the return spring. For sizing, this translates to a safe working load of roughly 280 N, or a vertical pull capacity of about 23.8 kg with a 2:1 safety margin. The built-in magnet (-S) supports CMSG, DMSG and EMSG position sensing.

Specifications follow the official AirTAC MI/MIC (ISO 6432) datasheet. Barrel & rod: stainless steel (round-body, riveted construction). Thread options: PT (blank) / G. Note: the Ø40 bore is a larger, non-ISO-6432 size.
Theoretical Output Force (Ø40mm)
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 466.8 N |
| 0.7 MPa | 677.9 N |
Single-acting pull: the spring extends the rod; air retracts it. Forces already net the spring; minimum working pressure is 0.2 MPa.

Where the Airtac MTI Single Acting Stainless Steel Mini Cylinder MTI40X10SU Is Used
Heavy-Duty Hold-Down
Maintains 280 N of safe clamping pressure on parts during machining, staying locked in the extended position if the air supply fails.
Normally-Closed Security Gate
Keeps a heavy access barrier shut by default, using 466.8 N of pneumatic pull to open the gate only when the system is pressurized.
Industrial Tensioning
Holds roughly 23.8 kg of vertical tension on cables or belts, relying on the spring to sustain the pull at rest without consuming air.
Is the Airtac MTI Single Acting Stainless Steel Mini Cylinder MTI40X10SU the Right Cylinder?
When sizing by pull force, this 40 mm bore provides 466.8 N at 0.5 MPa, sitting above the 32 mm option which yields 295.6 N under the same pressure. As the largest available bore in the series, there is no larger standard size to step up to. Ensure your air supply delivers at least 0.2 MPa to retract the rod against the spring. The 10 mm stroke is well within the 80 mm standard limit for this bore. It features a U-type 90-degree back cover and uses fixed TPU bumper pads rather than adjustable air cushions.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/R/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/R/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac MTI Single Acting Stainless Steel Mini Cylinder MTI40X10SU FAQ
It delivers a 466.8 N pull force at 0.5 MPa and 677.9 N at 0.7 MPa. It requires a minimum of 0.2 MPa to overcome the internal spring. The cylinder is single-acting pull type, meaning the rod rests in the extended position and retracts only when air is applied.
Yes, the -S suffix indicates a built-in piston magnet, allowing you to mount CMSG, DMSG or EMSG reed or electronic switches. The stainless steel construction provides mild corrosion resistance, but note it uses fixed TPU bumpers, not adjustable air cushions.
