About the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X30SCA
Delivering 25.1 N of push force at 0.5 MPa, the AirTAC MI8X30SCA is a compact double-acting round-body mini cylinder built for light-duty automation. Its stainless-steel barrel and Ø4 mm rod shrug off mild corrosion, giving it a real edge over painted-steel alternatives in damp or washdown-prone environments. The riveted construction keeps the body light, while fixed TPU bumper pads absorb the impact at stroke extremes without offering adjustable cushioning.
This 8 mm bore unit features an M5x0.8 port and a CA rear pivot cover for clevis mounting. Because it carries the -S suffix, a built-in piston magnet allows direct mounting of CMSG, DMSG or EMSG switches for position sensing. For practical sizing, plan for a safe working load of roughly 15 N, which means it can comfortably lift a 1.3 kg component vertically with a 2:1 safety margin.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X30SCA Is Used
Electronic Component Sorting
Actuates tiny diverter gates on PCB assembly lines, using the 15 N safe working load to flick lightweight plastic trays into inspection lanes.
Lab Sample Ejection
Pushes 1.3 kg vial racks out of centrifuge slots, relying on the stainless build to withstand humid laboratory conditions and chemical wipe-downs.
Micro-Clamp Actuation
Drives small pneumatic clamps in jewellery manufacturing, where the 30 mm stroke and CA pivot mount secure delicate wire frames for soldering.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X30SCA the Right Cylinder?
When sizing this 8 mm bore, stepping up to the Ø10 model increases the 0.5 MPa push force to 39.3 N, while no smaller AirTAC MI bore exists below this. The 30 mm stroke keeps the rod short and highly resistant to bending, but if your mechanism loses air or the valve centres, the piston will drift and drop the load. The fixed TPU bumpers only decelerate the end-of-stroke impact, so install an external pilot check valve or rod lock if you need to hold a vertical position. Ensure your rear clevis matches the CA pivot cover, and leverage the -S magnet for solid state or reed 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 0.15 – 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 MI8~12 Stainless Steel Mini Cylinder MI8X30SCA FAQ
This 8 mm bore cylinder features an M5x0.8 port. It generates 25.1 N push and 18.8 N pull at 0.5 MPa, increasing to 35.2 N push and 26.4 N pull at 0.7 MPa. The theoretical maximum force is 5.1 kgf at 1.0 MPa.
Yes, the Ø8 bore utilises standard ISO 6432 mounting dimensions for easy bracket interchangeability. Furthermore, the -S suffix denotes an integrated magnet, allowing you to directly mount CMSG, DMSG or EMSG switches along the body for precise end-of-stroke detection.
