Airtac MTI Single Acting Stainless Steel Mini Cylinder MTI25X80CA
The AirTAC Airtac MTI Single Acting Stainless Steel Mini Cylinder MTI25X80CA is a genuine single acting, pull (spring return) round-body mini air cylinder with a Ø25mm bore and 80mm stroke, 1/8" air ports and a stainless-steel barrel and rod for mildly corrosive environments. Its ISO 6432 mounting interface makes it a compact drop-in for standard mini-cylinder fixtures.

About the Airtac MTI Single Acting Stainless Steel Mini Cylinder MTI25X80CA
Delivering a net pull force of 151.1 N at 0.5 MPa, this stainless-steel round-body mini cylinder is built for spring-extend, single-acting pull operation. Because an internal spring drives the rod out at rest, the cylinder stays extended during an air loss event, providing a fail-safe forward stop. Air fed through the 1/8" port retracts the 10 mm rod, requiring at least 0.2 MPa to overcome the spring. The stainless barrel and rod resist mild corrosion and washdown environments.
This model conforms to the ISO 6432 mounting interface for easy bracket drops-ins. It features a CA rear pivot clevis for angular alignment and fixed TPU bumpers to soften stroke ends. For buyers sizing a vertical lift, it pulls or holds about 7.7 kg with a 2:1 safety margin. Note this SKU lacks the -S magnet, so it cannot host CMSG, DMSG or EMSG sensors.

Theoretical Output Force (Ø25mm)
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 151.1 N |

Where the Airtac MTI Single Acting Stainless Steel Mini Cylinder MTI25X80CA Is Used
Fail-Safe Hold-Down Clamp
Keeps a workpiece clamped forward by spring force if air pressure drops, using the 151.1 N pull to release the part only when compressed air is applied.
Tensioning Mechanism
Maintains steady belt or cable tension with its normally extended rod, retracting via the 1/8" port to slacken the line during changeovers.
Normally-Closed Gate Stop
Blocks a conveyor lane by default with the spring-extended rod, pulling back to open the lane for sorting when actuated at 0.5 MPa.
Is the Airtac MTI Single Acting Stainless Steel Mini Cylinder MTI25X80CA the Right Cylinder?
When sizing by pull force, this 151.1 N unit sits above the 94.4 N bore-20 and below the 295.6 N bore-32. It provides a safe working load of roughly 91 N, making it ideal for moderate tensioning or hold-down tasks. Remember that the spring requires a minimum 0.2 MPa to retract the rod.
The 80 mm stroke is the maximum standard travel for this bore before entering non-standard territory. The CA rear clevis suits pivoting loads, but if you need position feedback, select the -S magnet variant to enable 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 MTI25X80CA FAQ
It provides a 151.1 N pull force at 0.5 MPa and 233.5 N at 0.7 MPa. It requires at least 0.2 MPa to overcome the internal spring. The rod is normally extended at rest and retracts only when air is applied.
No, this specific SKU does not include a magnet. You must select the -S variant to use CMSG, DMSG or EMSG sensors. It is a single-acting pull cylinder with a stainless barrel and CA clevis, not a double-acting profile body.
