About the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X35U
Delivering 25.1 N of push force at 0.5 MPa, the AirTAC MI8X35U is a compact double-acting round-body mini cylinder built for tight spaces. Its stainless-steel barrel and Ø4 mm rod shrug off mild corrosion, making it superior to painted alternatives in damp or washdown environments. The riveted construction keeps the body light, while fixed TPU bumper pads absorb end-of-stroke impact.
Because this SKU lacks the -S suffix, it cannot accept CMSG, DMSG or EMSG magnetic switches. The U suffix denotes a 90-degree rear cover for compact port and pivot routing. For practical sizing, plan for roughly 15 N of usable work at 0.5 MPa, which translates to lifting about 1.3 kg vertically with a safe 2:1 margin.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X35U Is Used
Micro Clamp Ejection
Pushes small plastic parts out of an injection mould tool using 25.1 N of force, where the stainless body resists residual mould moisture.
Lightweight Divert Gate
Actuates a tiny routing flap on a packaging conveyor, with the 90-degree U cover fitting neatly into the constrained frame gap.
Lab Sample Positioning
Indexes light analytical trays across a 35 mm stroke in wet laboratory cabinets, benefiting from the corrosion-resistant rolled barrel.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X35U the Right Cylinder?
As the smallest bore in the MI family, the Ø8 offers minimal footprint but limited power; stepping up to the Ø10 bore raises push force to 39.3 N at 0.5 MPa if this 25.1 N unit stalls. The 35 mm stroke is well within the 150 mm standard maximum, keeping the rod bending risk low. The U-style 90-degree back cover dictates your rear mounting orientation.
Remember that a plain double-acting cylinder drifts if air pressure drops or the valve is centred—the TPU bumpers only soften the stroke end, they do not act as a brake. To hold a vertical load securely, add an external pilot check valve or a dedicated rod lock.
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 MI8X35U FAQ
This Ø8 mm bore cylinder has an M5x0.8 port and a male M4x0.7 rod thread. It generates 25.1 N push and 18.8 N pull at 0.5 MPa, or 35.2 N push and 26.4 N pull at 0.7 MPa. The theoretical maximum force is 5.1 kgf at 1.0 MPa.
Yes, the Ø8 bore uses the ISO 6432 mounting interface, so it drops into standard mini-cylinder clevises and brackets. However, because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG switches; you would need the MI8X35US variant for position sensing.
