About the Airtac MTI Single Acting Stainless Steel Mini Cylinder MTI8X30SCA
Designed for compact assemblies, this stainless-steel round-body mini cylinder uses an internal spring to keep the piston rod extended at rest, while compressed air via the M5x0.8 port retracts it. As a single-acting pull type, it delivers a net pulling force of 12.3 N at 0.5 MPa. The fail-safe extend behavior ensures your mechanism stays engaged if air pressure drops. It conforms to ISO 6432 mounting dimensions for easy bracket integration.
The Ø8 mm bore and 30 mm stroke suit light-duty tasks. The stainless barrel and rod resist mild corrosion. With a safe working load of roughly 7 N, it can vertically pull or hold about 0.6 kg with a 2:1 margin. The built-in magnet (-S) supports CMSG, DMSG, or EMSG sensors, while the CA back cover provides a pivot mount.

Where the Airtac MTI Single Acting Stainless Steel Mini Cylinder MTI8X30SCA Is Used
Fail-Safe Gate Stop
Keeps a lightweight access gate closed by spring force. Air retracts the rod to open the gate, ensuring it defaults to closed on air loss.
Light Tensioning Arm
Maintains steady tension on a thin filament or wire. The 12.3 N pull force securely draws the tensioning pulley back during operation.
Small Parts Hold-Down
Holds a light cardboard flap in place on a packaging line. The spring-extended rod stays engaged securely even if the air supply is interrupted.
Is the Airtac MTI Single Acting Stainless Steel Mini Cylinder MTI8X30SCA the Right Cylinder?
Size this actuator strictly by its pull force. The MTI8X30SCA yields 12.3 N at 0.5 MPa; if your load requires less, there is no smaller bore in the range, so look at reducing pressure. If you need more force, step up to the Ø10 bore, which provides 23.2 N at 0.5 MPa. Remember that extension is spring-only, so do not quote a pneumatic push force.
This unit requires at least 0.2 MPa of air to overcome the return spring. The 30 mm stroke falls within the standard 50 mm limit for this bore. Mounting is straightforward using the CA clevis back cover, and the -S magnet option 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 MTI8X30SCA FAQ
It provides a single-acting pull force of 12.3 N at 0.5 MPa and 19.9 N at 0.7 MPa. It requires a minimum operating pressure of 0.2 MPa to retract the rod against the spring. At rest or on air loss, the spring keeps the rod fully extended.
Yes, the -S suffix indicates a built-in piston magnet, allowing you to mount CMSG, DMSG, or EMSG sensors. The CA back cover acts as a rear clevis pivot, and the unit uses an M5x0.8 port for air connection.
