About the Airtac MI8~12 Stainless Steel Mini Cylinder MI10X125U
Generating 39.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles light actuation with a 125 mm stroke. The Ø10 mm bore uses an M5x0.8 port and an M4x0.7 male rod thread. Its stainless barrel and piston rod resist mild corrosion, giving it an edge over painted alternatives in damp processing areas. Fixed TPU bumper pads absorb the impact at stroke extremes without offering adjustable cushioning.
Because the 39.3 N rating represents an ideal maximum, plan for a real working load of roughly 24 N to maintain smooth operation. Vertically, this translates to lifting about 2 kg safely when applying a 2:1 margin. This SKU lacks a magnet, so it cannot host CMSG, DMSG or EMSG sensors; adding an -S variant enables that switch capability.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI10X125U Is Used
PCB Ejector Pins
Pushes delicate printed circuit boards out of test fixtures using a safe 24 N working load, preventing damage to surface-mounted components.
Small Parts Diverter
Actuates a lightweight flap on a packaging line to sort small plastic housings, utilising the 90-degree U cover for horizontal mounting.
Lab Sample Ejection
Ejects vial racks from analytical equipment in humid laboratory environments where the stainless-steel barrel prevents mild corrosion.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI10X125U the Right Cylinder?
When sizing this 10 mm bore, dropping down to the Ø8 model reduces the push force to 25.1 N at 0.5 MPa, while stepping up to the Ø12 bore increases it to 56.5 N. This unit features a U-type back cover, orienting the rear port 90 degrees to the body for tight spatial envelopes. It conforms to ISO 6432 mounting dimensions, ensuring it drops directly into standard mini-cylinder clevises and brackets.
Remember that venting the air supply causes the piston to drift, as the standard construction lacks a holding mechanism. The fixed bumpers only decelerate the end-of-stroke impact and never act as a brake, so suspend a load using a pilot-operated check valve or external rod lock. Furthermore, the 125 mm stroke demands careful alignment to prevent side-loading and rod bending.
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 MI10X125U FAQ
This double-acting cylinder uses an M5x0.8 port. It generates 39.3 N push and 33 N pull at 0.5 MPa, 55 N push and 46.1 N pull at 0.7 MPa, with a theoretical maximum of 8 kgf at 1.0 MPa.
No, this specific SKU lacks the internal magnet required for switches. You must select the -S variant to mount CMSG, DMSG or EMSG magnetic sensors. The unit relies on fixed TPU bumper pads for end-of-stroke deceleration rather than an adjustable air cushion.
