Airtac MI8~12 Stainless Steel Mini Cylinder MI12X20SUTC
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI12X20SUTC is a genuine double acting round-body mini air cylinder with a Ø12mm bore and 20mm 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 MI12X20SUTC
Delivering 56.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact 20 mm strokes with efficiency. The Ø12 mm bore uses an M5x0.8 port and a Ø6 mm piston rod with an M6x1.0 male thread. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Built-in fixed TPU bumper pads decelerate the stroke end, while the riveted construction keeps the body light.
With a 56.5 N push rating at 0.5 MPa, you can plan for a safe working load of about 34 N of real work. For vertical lifting, that equates to raising roughly 2.9 kg with a 2:1 safety margin. Because this SKU includes the -S magnet, it supports CMSG, DMSG and EMSG reed or electronic switches. The U back cover provides a 90-degree port orientation, and it drops directly into standard ISO 6432 mini-cylinder mounting dimensions.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X20SUTC Is Used
PCB Component Insertion
Uses the 34 N safe working load to press small electronic connectors onto circuit boards within dense assembly machinery.
Package Diverting Gate
Leverages the 20 mm stroke and TC trunnion mount to actuate a lightweight routing flap for small parcels on a sorting line.
Lab Sample Ejection
Relies on the stainless steel construction and 2.9 kg vertical lift capacity to push prepared test tubes out of a washdown carousel.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X20SUTC the Right Cylinder?
When sizing this bore, stepping down to the Ø10 MI yields 39.3 N of push, whereas moving up to the Ø16 MI provides 100.5 N at 0.5 MPa. This model features a TC trunnion mount, which pairs with the U back cover for versatile 90-degree positioning. Remember that a plain cylinder drifts if air is lost or the valve is centred; the TPU bumpers only soften the stroke end rather than locking the load. For position holding, add an external rod lock or a pilot-operated check valve. The short 20 mm stroke minimizes rod-bending side loads, making it highly robust for tight spaces.
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 MI12X20SUTC FAQ
This Ø12 mm bore cylinder features an M5x0.8 port and generates a push force of 56.5 N and a pull force of 42.4 N at 0.5 MPa. At 0.7 MPa, push is 79.1 N and pull is 59.4 N. The theoretical maximum force is 11.5 kgf at 1.0 MPa.
The fixed TPU bumper pads only decelerate the stroke end; they do not act as a brake, so the piston will drift if air is lost. Use an external rod lock or pilot check valve to hold a load. Because this model has the -S magnet, it accepts CMSG, DMSG and EMSG switches for position sensing.
