Airtac MTI Single Acting Stainless Steel Mini Cylinder MTI8X30CA
The AirTAC Airtac MTI Single Acting Stainless Steel Mini Cylinder MTI8X30CA is a genuine single acting, pull (spring return) round-body mini air cylinder with a Ø8mm bore and 30mm stroke, M5×0.8 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 MTI8X30CA
Generating 12.3 N of pull at 0.5 MPa, this stainless-steel round-body mini cylinder uses an internal spring to keep the rod extended at rest, while compressed air retracts it. Because it rests extended, the rod stays forward during an air loss to provide a fail-safe stop or hold-down. The spring-return design requires only a single M5x0.8 air line, saving space and air consumption compared to double-acting units.
Built on the ISO 6432 mounting interface, it drops into standard mini brackets and features a CA rear pivot cover. For sizing, its safe working load is roughly 7 N, or it can vertically pull about 0.6 kg with a 2:1 margin. This non-magnet SKU cannot host position sensors; add the -S option for CMSG/DMSG/EMSG switches.

Where the Airtac MTI Single Acting Stainless Steel Mini Cylinder MTI8X30CA Is Used
Fail-Safe Hold-Down
Keeps light parts clamped with its 12.3 N pull, while the spring maintains downward pressure if the air supply drops.
Normally-Closed Gate
Blocks a small lane or chute at rest; air retracts the 4 mm rod to open the path only when signaled.
Light Tensioning
Applies steady spring tension to a belt or web, using air to slacken the line for maintenance.
Is the Airtac MTI Single Acting Stainless Steel Mini Cylinder MTI8X30CA the Right Cylinder?
Size this bore strictly by pneumatic pull force, as the spring only handles extension. The 8 mm bore yields 12.3 N at 0.5 MPa; if your load exceeds the 7 N safe working threshold, step up to the 10 mm bore (23.2 N). There is no smaller standard MTI bore below 8 mm. Factor in the 0.2 MPa minimum pressure required to overcome the return spring.
This 30 mm stroke sits safely within the 50 mm spring limit for 8 mm bores. The CA pivot cover suits angular movements, and since this specific SKU lacks a magnet, you must select an -S variant if you need CMSG, DMSG or EMSG 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 MTI8X30CA FAQ
It provides a 12.3 N pull at 0.5 MPa and 19.9 N at 0.7 MPa. An internal spring holds the rod extended at rest, and it requires at least 0.2 MPa of air pressure to retract the rod.
No, this base SKU lacks a piston magnet and cannot accept CMSG, DMSG or EMSG switches. You must specify the -S option to enable sensing.
