Airtac MI8~12 Stainless Steel Mini Cylinder MI8X30CALB
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI8X30CALB is a genuine double acting 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 MI8~12 Stainless Steel Mini Cylinder MI8X30CALB
Delivering 25.1 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles short 30 mm strokes with precision. The riveted barrel and Ø4 mm rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments. Its compact footprint uses the ISO 6432 mounting interface, dropping directly into standard mini-cylinder brackets and clevises.
Because this SKU lacks the -S suffix, it cannot accept CMSG, DMSG or EMSG magnetic sensors. Fixed TPU bumper pads absorb the impact at stroke extremes without offering adjustable cushioning. For practical sizing, plan for roughly 15 N of usable work at 0.5 MPa, which translates to safely lifting about 1.3 kg vertically against gravity.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X30CALB Is Used
Micro-Clamp Actuation
Drives small electronic component clamps on PCB assembly lines where a 15 N working force securely holds delicate parts without crushing them.
Lab Sample Diverting
Pivots via the CA clevis to push lightweight fluidic diverters in diagnostic machinery, benefiting from the stainless build during frequent chemical wipe-downs.
Small Part Ejection
Ejects tiny moulded plastic parts from a 30 mm recess using the M4 rod thread, relying on fixed TPU pads to quietly stop the stroke end.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X30CALB the Right Cylinder?
When sizing this 8 mm bore, note there is no smaller option in the MI family, while stepping up to the Ø10 bore raises the push force to 39.3 N at 0.5 MPa. This model includes a CA rear pivot cover and an LB foot mounting accessory for versatile installation. Air connects via an M5×0.8 port, and the male rod features an M4×0.7 thread.
Keep in mind that a standard double-acting cylinder drifts if air pressure drops or the valve is centred, as the TPU pads only soften the end of travel rather than locking the rod. For applications requiring a held load, incorporate an external rod lock or a pilot-operated check valve. The short 30 mm stroke keeps rod bending stress minimal even under lateral loads.
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 MI8X30CALB 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.
No, this specific SKU does not include a magnet, so CMSG, DMSG or EMSG switches will not function. You must select an -S variant to enable position sensing. It uses the ISO 6432 mounting interface and includes fixed TPU bumper pads rather than an adjustable air cushion.
