About the Airtac MTI Single Acting Stainless Steel Mini Cylinder MTI40X10R
Delivering a robust 466.8 N of pull force at 0.5 MPa, this AirTAC round-body mini cylinder is built for demanding tensioning and retraction tasks. The MTI40X10R is a single-acting, spring-return pull type: compressed air retracts the rod via the 1/4" port, while an internal spring extends it. It rests in the extended position, providing a fail-safe forward stop that stays engaged if air pressure is lost.
The stainless-steel barrel and rod resist mild corrosion and washdown environments. Because this SKU lacks the -S magnet option, it cannot accept position sensors. Fixed TPU bumper pads soften the stroke ends, though they do not lock the load mid-stroke. For sizing, this bore provides a safe working load of about 280 N, or roughly 23.8 kg of vertical lift with a 2:1 margin.

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 |

Where the Airtac MTI Single Acting Stainless Steel Mini Cylinder MTI40X10R Is Used
Heavy-Duty Hold-Down
Uses the spring-extended rest state to keep a heavy workpiece clamped. Air pulls the rod back to release the part, ensuring the clamp stays engaged during an air loss.
Normally-Closed Gate
Acts as a robust physical stop on a conveyor line. The rod stays extended to block flow by default, and 0.5 MPa air retracts it to yield a 466.8 N pull force for clearing product.
Tensioning Mechanism
Maintains constant tension on a belt or cable. The spring keeps the line taut at rest, while pneumatic retraction provides precise slack adjustment under load.
Is the Airtac MTI Single Acting Stainless Steel Mini Cylinder MTI40X10R the Right Cylinder?
Size this actuator strictly by its net pull force. If 466.8 N at 0.5 MPa is excessive, step down to the Ø32 bore, which yields 295.6 N; as Ø40 is the largest in this series, no larger standard option exists. Remember that extension is spring-only, so you must apply at least 0.2 MPa of air to overcome the spring and retract the rod.
The 10 mm stroke sits well within the 80 mm standard limit for this bore. Mounting relies on the R axial-in rear cover style alongside standard LB, FA, SDB, or TC brackets. Without the -S magnet, this specific unit cannot host CMSG, DMSG, or EMSG sensors.
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 MTI40X10R FAQ
It is a single-acting pull cylinder that rests extended. It requires at least 0.2 MPa to retract the rod against the spring. The net pull force is 466.8 N at 0.5 MPa and 677.9 N at 0.7 MPa. It produces no pneumatic push force.
No, this specific SKU lacks a magnet and cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. It is a stainless round-body mini cylinder with fixed TPU bumpers, not an adjustable air cushion unit.
