About the Airtac MTI Single Acting Stainless Steel Mini Cylinder MTI40X60U
Delivering 466.8 N of retraction force at 0.5 MPa, this AirTAC round-body mini cylinder uses compressed air to pull the load and an internal spring to push it back out. Because the spring holds the rod out at rest, the mechanism stays safely extended even if air pressure drops completely. This fail-safe behavior makes it ideal for holding gates closed or maintaining tension without constantly consuming air. The stainless steel barrel and rod resist mild corrosion and washdown environments.
As a single-acting pull type, it requires at least 0.2 MPa of input pressure to overcome the return spring and initiate the retraction stroke. This specific SKU features a 90-degree U back cover and a 1/4 inch air port. It provides a calculated safe working load of roughly 280 N, meaning it can vertically pull or hold about 23.8 kg with a 2:1 safety margin. Note that this non-magnet version cannot accept position sensors.

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 MTI40X60U Is Used
Fail-Safe Gate Holding
Keeps a heavy access door pushed closed and locked by spring force, using the 466.8 N pull only to open it when air is applied.
Tensioning Systems
Maintains steady belt or cable tension at rest, retracting the 16 mm rod to release the tension only when pressurized.
Pallet Hold-Down
Holds packaging material firmly in place during transit, automatically snapping back to the extended hold position if the air supply fails.
Is the Airtac MTI Single Acting Stainless Steel Mini Cylinder MTI40X60U the Right Cylinder?
When sizing this 40 mm bore, verify your load requires a pull force of 466.8 N at 0.5 MPa or up to 677.9 N at 0.7 MPa. If your application needs less force, stepping down to the 32 mm bore provides 295.6 N at 0.5 MPa, which may better suit lighter tensioning tasks. Since 40 mm is the largest available size in this series, loads exceeding 677.9 N will require a different cylinder family entirely.
Remember that the internal spring limits the standard travel to a maximum of 80 mm, making this 60 mm stroke a standard option. Ensure your system can supply at least 0.2 MPa to retract the rod against the spring. For position feedback, you would need the -S magnet variant to use CMSG, DMSG, or EMSG sensors, as this base model lacks sensing capability.
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 MTI40X60U FAQ
It generates 466.8 N of pull force at 0.5 MPa and 677.9 N at 0.7 MPa. The rod rests in the extended position and requires a minimum of 0.2 MPa to overcome the internal spring and retract.
No, this specific SKU does not have a magnet. You must purchase the -S variant to use CMSG, DMSG, or EMSG sensors. It is a single-acting pull cylinder, not double-acting.
