About the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X75SCA
Generating 25.1 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles precise light-duty tasks. The Ø8 mm bore uses an M5x0.8 air port and a Ø4 mm piston rod with an M4x0.7 male thread. Because the barrel and rod are stainless, the riveted construction naturally resists mild corrosion in damp or washdown environments better than painted alternatives. An integrated magnet allows CMSG, DMSG or EMSG switches to track position, while the fixed TPU bumper pads quietly absorb end-of-stroke impacts.
For practical sizing, plan for a real work load of roughly 15 N, which is about 60 percent of the 0.5 MPa rating. In a vertical lift setup, this equates to raising a 1.3 kg mass with a safe 2:1 margin. The CA rear pivot cover provides a clevis mount ideal for articulating mechanisms, and the body conforms to ISO 6432 mounting dimensions for easy bracket integration.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X75SCA Is Used
Micro Pick-and-Place
Ideal for moving small electronic components on PCB assembly lines, utilizing the 1.3 kg vertical lift capacity and CMSG sensor feedback for precise end-of-stroke detection.
Lab Dispenser Actuation
Drives tiny pump or valve mechanisms in analytical instruments where the stainless body resists mild chemical corrosion and the compact 8 mm bore fits tight enclosures.
Small Part Ejection
Pushes lightweight plastic moulded parts out of a die using 25.1 N of force, with the CA pivot clevis accommodating slight misalignment during the ejection arc.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X75SCA the Right Cylinder?
When sizing this 8 mm bore unit, note there is no smaller standard MI option below it. If your application requires more force, stepping up to the Ø10 bore increases push force to 39.3 N at 0.5 MPa. This specific SKU includes the -S magnet for position sensing and the CA clevis back cover for pivot mounting. Remember that a standard cylinder drifts if air pressure drops or the valve is centered; the TPU bumpers only decelerate the stroke end and will not lock the load. Use a pilot-operated check valve if you need to hold a vertical load safely. At 75 mm, the stroke is well within the 150 mm maximum for this bore, keeping rod bending stress low.
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 MI8X75SCA FAQ
The Ø8 mm bore has an M5x0.8 air port. It generates 25.1 N push and 18.8 N pull at 0.5 MPa, 35.2 N push and 26.4 N pull at 0.7 MPa, with a theoretical maximum force of 5.1 kgf at 1.0 MPa.
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper pads only decelerate the rod near the stroke end; they do not function as a brake or lock. A pilot-operated check valve is required for load holding.
