About the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X20CA
Delivering 56.5 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles compact actuation with a 20 mm stroke. The Ø12 mm bore features an M5x0.8 port and an M6x1.0 male rod thread. Its stainless barrel and rod naturally resist mild corrosion, offering a distinct advantage over painted alternatives in damp or washdown settings. Built with fixed TPU bumper pads to soften stroke-end impacts, the riveted round body remains light and inherently compact.
Because it conforms to ISO 6432 mounting dimensions, this unit drops directly into standard mini-cylinder brackets and clevises for straightforward design integration. For practical sizing, plan for roughly 34 N of real work at 0.5 MPa, which translates to lifting about 2.9 kg vertically with a 2:1 safety margin. The CA rear pivot cover allows articulated mounting, though note this specific SKU lacks a magnet and cannot support CMSG, DMSG, or EMSG sensors.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X20CA Is Used
Small Part Ejection
Uses the 56.5 N push force to knock lightweight plastic mouldings from an injection press chute in confined assembly cells.
Package Diverter Gate
Leverages the 20 mm stroke and CA pivot rear to swing a small deflector plate, routing small cardboard cartons on a packing line.
Lab Sample Pusher
Advances test tubes into a centrifuge carousel, benefiting from the stainless construction during frequent alcohol washdowns.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X20CA the Right Cylinder?
When sizing this 20 mm stroke unit, the Ø12 bore sits between the smaller Ø10 (39.3 N push @0.5 MPa) and the larger Ø16 (100.5 N push @0.5 MPa). Choose this model for tight pivot mechanisms where the CA clevis rear cover is required. If your application requires position sensing, you must select the -S magnet variant instead, as this base configuration cannot accept a switch. For higher energy cycles, consider the MIC series which offers adjustable air cushions, whereas this base MI relies solely on its fixed TPU bumpers.
Remember that a plain double-acting cylinder drifts when air pressure is removed or the valve is centered. The bumpers only decelerate the piston near the stroke end and do not function as a lock or brake. To suspend a load safely during an air loss event, install an external rod lock or a pilot-operated check valve in the air line.
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 MI12X20CA FAQ
This double-acting cylinder has an M5x0.8 port and generates 56.5 N push / 42.4 N pull at 0.5 MPa, and 79.1 N push / 59.4 N pull at 0.7 MPa. The theoretical maximum force is 11.5 kgf at 1.0 MPa.
No, this base SKU lacks a piston magnet and cannot accept CMSG, DMSG, or EMSG switches. You must specify the -S variant for sensor compatibility. It uses ISO 6432 mounting dimensions and features a CA pivot clevis rear cover.
