About the Airtac MTI Single Acting Stainless Steel Mini Cylinder MTI40X10SR
Generating 466.8 N of pull at 0.5 MPa, this stainless round-body mini cylinder is built for spring-extend, pull-type actuation. The internal spring drives the rod out at rest, meaning the rod stays extended during an air loss to provide a fail-safe forward stop. Air pressure retracts the rod, requiring at least 0.2 MPa to overcome the spring. The Ø40 bore uses a 1/4" port and a Ø16 rod.
With a 0.5 MPa pull force, the computed safe working load is roughly 280 N, translating to a vertical lift capacity of about 23.8 kg with a 2:1 safety margin. The stainless barrel and rod resist mild corrosion and washdown environments. The -S suffix indicates a built-in piston magnet for CMSG, DMSG or EMSG sensors, and the rear R cover provides an axial port orientation.

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 MTI40X10SR Is Used
Heavy Hold-Down Clamps
Holds heavy components firmly in place during machining, using the 466.8 N pull force to retract, while the spring ensures the clamp stays engaged if air pressure drops.
Normally-Closed Security Gates
Keeps heavy access gates shut by default. Compressed air pulls the 40 mm rod back to open the gate, and the internal spring automatically extends it closed.
High-Tension Web Guides
Maintains robust tension on conveyor belts or web materials by pulling the rod back against the material, offering a safe working load of roughly 280 N.
Is the Airtac MTI Single Acting Stainless Steel Mini Cylinder MTI40X10SR the Right Cylinder?
For sizing, this 40 mm bore yields 466.8 N of pull at 0.5 MPa, sitting above the Ø32 bore which provides 295.6 N. If your application requires less force, stepping down to Ø32 is advisable, as there is no larger standard MTI bore. Remember that the spring requires a minimum 0.2 MPa to retract the rod, and the 10 mm stroke is well within the 80 mm spring-limited standard for this bore. Mounting options include LB foot, FA flange, SDB pivot-block and TC trunnion, while the -S magnet enables position sensing.
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 MTI40X10SR FAQ
It provides a pull force of 466.8 N at 0.5 MPa and 677.9 N at 0.7 MPa. The rod is normally extended at rest via an internal spring. It requires a minimum of 0.2 MPa to overcome the spring and retract the rod.
Yes. The -S suffix means this single-acting pull cylinder includes a built-in magnet for CMSG, DMSG or EMSG sensors. Without the -S suffix, a SKU cannot accept a sensor.
