About the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X150SCA
Generating 25.1 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact actuation. The Ø8 mm bore uses an M5×0.8 air port and a 4 mm piston rod with an M4×0.7 male thread. At its maximum standard stroke of 150 mm, it incorporates a CA pivot clevis back cover for articulated mounting.
The riveted stainless barrel and rod shrug off mild corrosion, outperforming painted alternatives in damp environments. Integrated fixed TPU bumper pads decelerate the piston at stroke ends without adjustable cushioning. Because it pushes with 25.1 N at 0.5 MPa, you can plan for roughly 15 N of actual work, lifting about 1.3 kg vertically with a 2:1 safety margin. The -S suffix equips the piston with a magnet for CMSG, DMSG or EMSG switches.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X150SCA Is Used
Lab Dispenser Routing
Shifts small reagent tubes on diagnostic machinery using a safe 15 N working load, relying on the stainless build to resist chemical humidity.
Micro-Clip Insertion
Pushes delicate spring clips into PCB assemblies where the 1.3 kg vertical lift capacity prevents damaging fragile surface-mount components.
Lightweight Diverter Gate
Pivots a small package routing flap via the CA clevis, operating at 150 mm stroke to redirect small parcels on conveyor lines.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X150SCA the Right Cylinder?
When sizing this 8 mm bore, stepping up to the MI12X150SCA increases your 0.5 MPa push force to 56.5 N, while no smaller AirTAC MI bore exists below it. The 150 mm stroke represents the maximum standard extension for this size, so maintaining strict alignment is critical to prevent rod bending over that travel distance. The CA rear pivot cover pairs naturally with an FA flange or LB foot at the front.
Remember that fixed TPU bumpers only soften end-of-stroke impacts; they do not function as a lock. If your application must prevent drift on air loss or a centred valve, add an external pilot-operated check valve or a dedicated rod lock. The integrated magnet allows direct CMSG or DMSG switch mounting for position feedback.
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 MI8X150SCA FAQ
This 8 mm bore cylinder features an M5×0.8 port and generates 25.1 N push / 18.8 N pull at 0.5 MPa, and 35.2 N push / 26.4 N pull at 0.7 MPa. The theoretical maximum force is 5.1 kgf at 1.0 MPa.
Yes, the 8 mm bore conforms to ISO 6432 mounting dimensions for standard mini-cylinder brackets. The -S magnet allows CMSG, DMSG and EMSG switches, while the stainless riveted body handles mild washdowns.
