About the Airtac MSI Single Acting Stainless Steel Mini Cylinder MSI8X30SCA
Delivering a net 18.6 N of push force at 0.5 MPa, this stainless-steel round-body mini cylinder uses compressed air to extend and an internal spring to retract. Because it is single-acting, you only need one M5x0.8 air line, which simplifies plumbing and saves air. The internal return spring also acts as a fail-safe, driving the rod back to its normally retracted rest position if air pressure drops.
Built to ISO 6432 mounting interface dimensions, the Ø8 mm barrel and Ø4 mm rod resist mild corrosion and washdown environments. With a practical safe working load of about 11 N, it can vertically lift roughly 0.9 kg with a 2:1 safety margin. It features a CA pivot back cover and a built-in magnet for position sensing.

Where the Airtac MSI Single Acting Stainless Steel Mini Cylinder MSI8X30SCA Is Used
Light Part Ejection
Uses the 18.6 N extend force to push small plastic or aluminum parts out of a machining fixture, with the spring safely retracting the rod on air loss.
Micro-Clamping
Holds delicate electronic components securely during assembly with an 11 N safe working load, releasing instantly when the single air line vents.
Sorting Gate Trigger
Actuates a lightweight diverter gate on a conveyor; the fail-safe retract ensures the gate returns to the default pass-through path if the air supply fails.
Is the Airtac MSI Single Acting Stainless Steel Mini Cylinder MSI8X30SCA the Right Cylinder?
Size this actuator by its push force: the Ø8 bore yields 18.6 N at 0.5 MPa, offering a compact footprint for light ejection tasks. If your application requires less force, note that this is the smallest available MSI bore, so you must rely on pressure regulation to scale down. For heavier loads, stepping up to the Ø10 bore provides 29.5 N at 0.5 MPa.
Remember that at least 0.2 MPa of input pressure is required to overcome the return spring before the rod can move. The 30 mm stroke sits safely within the 50 mm spring-limited standard for this bore. The included -S magnet enables CMSG, DMSG, or EMSG sensors, and the CA back cover provides a rear pivot mount.
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 MSI Single Acting Stainless Steel Mini Cylinder MSI8X30SCA FAQ
This single-acting push cylinder generates 18.6 N of force at 0.5 MPa and 28.7 N at 0.7 MPa. It requires a minimum of 0.2 MPa to overcome the internal return spring. When air is released, the spring retracts the rod to its normally retracted rest state.
Yes, the -S suffix denotes a built-in piston magnet compatible with CMSG, DMSG, and EMSG switches. The cylinder does not hold loads mid-stroke; the spring only retracts the rod to rest on air loss. It features a stainless steel build and an M5x0.8 port.
