About the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X35U
Delivering 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 Ø12 mm bore uses an M5×0.8 air port and a Ø6 mm piston rod with an M6×1.0 male thread. Its stainless barrel and rod resist mild corrosion, giving it an edge over painted alternatives in damp environments. Fixed TPU bumper pads absorb stroke-end impact, while the riveted construction keeps the body light. The rear U-style cover provides a 90-degree mounting orientation for tight layouts.
Because the 56.5 N rating is theoretical, plan for a real working load of about 34 N at 0.5 MPa. For vertical moves, this translates to safely lifting roughly 2.9 kg with a 2:1 safety margin. Conforming to ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder brackets and clevises. Note that this specific SKU lacks a magnet, so it cannot host CMSG, DMSG, or EMSG sensors without upgrading to the -S variant.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X35U Is Used
Electronic Component Sorting
Pushes small PCBs or connectors along a conveyor lane using a safe 34 N working load, relying on the 35 mm stroke for rapid indexing.
Lab Dispenser Actuation
Drives a micro-valve or pipette head in damp laboratory settings, where the stainless rod prevents mild corrosion from repeated washdowns.
Small Parts Clamping
Secures delicate plastic housings during machining via the 90-degree U cover, applying just enough hold without crushing the material.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X35U the Right Cylinder?
When sizing this 35 mm stroke actuator, compare it against neighbouring bores: the smaller Ø10 generates 39.3 N push, while the larger Ø16 provides 100.5 N at 0.5 MPa. If your fixture loses air or the valve centres, be aware the piston will drift, as the TPU bumpers only decelerate the end of travel and act as neither a brake nor a lock. To suspend a load securely, integrate an external rod lock or a pilot-operated check valve. The 90-degree U back cover suits corner installations, and you can pair the body with LB foot, FA flange, SDB pivot, or TC trunnion brackets. For faster cycle speeds, the MIC variant offers adjustable air cushions.
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 MI12X35U FAQ
This Ø12 mm bore cylinder features an M5×0.8 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 specific SKU does not include a magnet, so CMSG, DMSG, or EMSG switches cannot be used. You must select the -S magnet variant for position sensing. It uses the ISO 6432 mounting interface and fixed TPU bumper pads rather than an adjustable cushion.
