Airtac MI8~12 Stainless Steel Mini Cylinder MI8X65SCA
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI8X65SCA is a genuine double acting round-body mini air cylinder with a Ø8mm bore and 65mm 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 MI8~12 Stainless Steel Mini Cylinder MI8X65SCA
Delivering 25.1 N of push force at 0.5 MPa, the AirTAC MI8X65SCA is a compact double-acting round-body mini cylinder built for tight spaces. 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 unit light, while fixed TPU bumper pads absorb the impact at stroke extremes.
Because this SKU includes the -S magnet, it is fully primed for CMSG, DMSG or EMSG position switches. The built-in CA pivot clevis on the rear cover simplifies angular mounting, and the Ø8 body uses the ISO 6432 mounting interface to drop directly into standard mini-cylinder brackets. Plan for roughly 15 N of actual work at 0.5 MPa, which translates to lifting about 1.3 kg vertically with a safe 2:1 margin.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X65SCA Is Used
Electronic Component Sorting
Uses the 25.1 N thrust to push lightweight PCBs or connectors into test fixtures without damaging delicate parts.
Lab Dispenser Actuation
The stainless build withstands mild chemical splashes, while the 65 mm stroke accurately drives a small pump head.
Small Part Ejection
The CA rear clevis allows pivoting to flick tiny plastic mouldings from a conveyor belt during high-speed cycling.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X65SCA the Right Cylinder?
When sizing this 8 mm bore, stepping up to the Ø10 model raises the push force to 39.3 N at 0.5 MPa, while the Ø8 is the smallest available option in the MI family. The 65 mm stroke sits well within the 150 mm standard limit, keeping the rod bending risk low even with side loads. Air connects via an M5×0.8 port, and the male rod thread is M4×0.7.
Remember that a standard double-acting cylinder drifts if air pressure drops or the valve is centred—the TPU pads only soften the end of travel and act purely as deceleration bumpers, never as a locking brake. To suspend a load safely mid-stroke, fit an external rod lock or a pilot-operated check valve.
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 MI8X65SCA FAQ
At 0.5 MPa it provides 25.1 N push and 18.8 N pull. At 0.7 MPa it provides 35.2 N push and 26.4 N pull. The theoretical maximum force is 5.1 kgf at 1.0 MPa. The air port is M5×0.8 and the male rod thread is M4×0.7.
No, the piston will drift. The fixed TPU bumper pads only decelerate the stroke end and do not act as a brake. You must add an external rod lock or pilot check valve to hold a suspended load. The -S magnet allows CMSG/DMSG/EMSG sensors to track position.
