About the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X80U
Generating 56.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact actuation with ease. The 12 mm bore and 80 mm stroke feature a 90-degree U rear cover, giving you flexible port and mounting orientation in tight spaces. Its stainless barrel and rod resist mild corrosion, outperforming painted alternatives in damp environments.
The riveted body uses fixed TPU bumper pads to soften stroke-end impact, and it conforms to ISO 6432 mounting dimensions for easy bracket integration. Operating on a 0.15-1.0 MPa pressure range with an M5x0.8 port, it yields a safe working load of roughly 34 N. It lifts about 2.9 kg vertically with a 2:1 margin. Note this SKU lacks a magnet, so it cannot host CMSG or DMSG sensors without the -S option.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X80U Is Used
Package Deflection Gates
Sorts light cardboard cartons on packaging lines by pushing diverters with its 56.5 N thrust and 80 mm travel distance.
Lab Sample Ejection
Ejects plastic test tube racks from testing carousels, where the stainless rod resists humidity and chemical wipe-downs.
Small Part Seating
Presses lightweight plastic caps into housings on electronics assembly lines, utilizing the 90-degree U cover for a compact footprint.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X80U the Right Cylinder?
When sizing this 12 mm bore against its neighbours, the smaller Ø8 generates 25.1 N while the larger Ø16 provides 100.5 N at 0.5 MPa, helping you bracket the 56.5 N output for your exact payload. The 80 mm stroke is well within the 250 mm standard limit, though you should still minimize side loads to prevent rod bending. You can mount it via LB foot, FA flange, or TC trunnion.
Because this is a standard double-acting cylinder, the piston will drift if air pressure drops or the valve is centred; the TPU bumpers only decelerate the stroke end and do not function as a braking lock. For suspended loads, add an external rod lock or pilot check valve. Also, since this specific code lacks an -S suffix, magnetic position sensing is not supported.
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 MI12X80U FAQ
At 0.5 MPa it pushes 56.5 N and pulls 42.4 N; at 0.7 MPa it pushes 79.1 N and pulls 59.4 N. The theoretical maximum force is 11.5 kgf at 1.0 MPa. This 12 mm bore cylinder uses an M5x0.8 air port.
No, this specific SKU does not have a magnet. You must select the -S variant to use CMSG, DMSG, or EMSG switches. It features fixed TPU bumper pads for deceleration and uses standard ISO 6432 mounting dimensions.
