Airtac MI8~12 Stainless Steel Mini Cylinder MI8X20CA
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI8X20CA is a genuine double acting round-body mini air cylinder with a Ø8mm bore and 20mm 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 MI8X20CA
Delivering 25.1 N of push force at 0.5 MPa, this 8 mm bore double-acting stainless steel round-body mini cylinder handles compact automation tasks. The 20 mm stroke operates at 30-800 mm/s, and the rear CA pivot cover allows direct clevis mounting. Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG position switches.
The riveted stainless barrel and Ø4 mm rod resist mild corrosion and washdown better than painted alternatives. Its ISO 6432 mounting dimensions drop straight into standard mini-cylinder brackets. Plan for roughly 15 N of actual work at 0.5 MPa, letting you lift about 1.3 kg vertically with a safe 2:1 margin. The M5×0.8 port and fixed TPU bumper pads complete the build.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X20CA Is Used
Micro-Clamp Actuation
Provides 25.1 N of push at 0.5 MPa to secure small electronic components on a PCB assembly line during soldering.
Lab Dispenser Dosing
Moves a 20 mm stroke to depress a pipette head, where the stainless body tolerates frequent chemical wipe-downs.
Light Part Ejection
Pushes delicate plastic mouldings out of a tool cavity using the CA pivot to accommodate slight angular misalignment.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X20CA the Right Cylinder?
When sizing this 8 mm bore, stepping up to the Ø10 variant raises push force to 39.3 N at 0.5 MPa, while Ø8 is the smallest available AirTAC MI option. The 20 mm stroke is well within the 150 mm standard maximum, keeping the rod rigid. The CA rear pivot is ideal for angular movement, but remember the TPU bumpers only decelerate the stroke end; they do not lock the rod. If your process drops air, the piston will drift, so fit an external pilot check valve to hold a suspended load.
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 MI8X20CA FAQ
This 8 mm bore cylinder pushes 25.1 N and pulls 18.8 N at 0.5 MPa. At 0.7 MPa it pushes 35.2 N and pulls 26.4 N. The theoretical maximum force is 5.1 kgf at 1.0 MPa, and the air port is M5×0.8.
No, this specific SKU does not include the -S magnet, so CMSG, DMSG or EMSG switches will not function. You must select an -S variant for position sensing. It uses ISO 6432 mounting dimensions and fixed TPU bumper pads rather than an adjustable air cushion.
