Airtac MI8~12 Stainless Steel Mini Cylinder MI12X75SU
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI12X75SU is a genuine double acting round-body mini air cylinder with a Ø12mm bore and 75mm 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 MI12X75SU
Delivering 56.5 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles compact automation with ease. The Ø12 mm bore uses an M5x0.8 air port and an M6x1.0 male rod thread, extending 75 mm on each cycle. Riveted round-body construction keeps the unit light, while the stainless barrel and rod resist mild corrosion in damp or washdown environments better than painted alternatives.
Because it carries a built-in piston magnet, this -S variant directly supports CMSG, DMSG and EMSG position switches. In practical terms, plan for roughly 34 N of actual work at 0.5 MPa, which translates to lifting about 2.9 kg vertically with a 2:1 safety margin. Fixed TPU bumper pads absorb the impact at stroke extremes, and the ISO 6432 mounting interface ensures it drops straight into standard mini-cylinder brackets and clevises.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X75SU Is Used
Textile Yarn Guides
Shifts a thread guide bracket precisely through 75 mm of travel, where the 56.5 N push force easily overcomes light guide friction.
Lab Sample Dispensing
Moves a pipette or sampling probe between stations, benefiting from the stainless build during frequent chemical wipe-downs.
Small Component Ejection
Kicks lightweight plastic parts out of an injection mould cavity, using the 2.9 kg vertical lift capacity to clear the tooling.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X75SU the Right Cylinder?
When sizing this 75 mm stroke actuator, compare it against its neighbours: the smaller Ø10 bore yields 39.3 N of push at 0.5 MPa, whereas stepping up to the Ø16 bore provides 100.5 N. This model features a U-type back cover, orienting the rear port at 90 degrees for tight spatial envelopes. You can mount it via LB foot, FA flange, SDB pivot or TC trunnion hardware. Remember that a standard cylinder drifts if air pressure drops or the valve is centred; the bumpers only decelerate the end of travel. Install an external pilot check valve if you need to suspend a load securely.
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 MI12X75SU FAQ
This 12 mm bore cylinder features an M5x0.8 port and generates 56.5 N push / 42.4 N pull at 0.5 MPa, 79.1 N push / 59.4 N pull at 0.7 MPa, with a theoretical maximum of 11.5 kgf at 1.0 MPa.
No, it relies on fixed TPU bumper pads to decelerate the stroke end rather than an adjustable air cushion. It uses the ISO 6432 mounting interface, and the included -S magnet allows CMSG, DMSG or EMSG sensors to track piston position.
