Airtac MI8~12 Stainless Steel Mini Cylinder MI8X5CA
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI8X5CA is a genuine double acting round-body mini air cylinder with a Ø8mm bore and 5mm 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 MI8X5CA
Delivering 25.1 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles tiny 5 mm strokes with a CA rear clevis. The riveted barrel and Ø4 mm rod shrug off mild washdown better than painted alternatives. Plan for roughly 15 N of actual work, letting you lift about 1.3 kg vertically with a 2:1 safety margin.
It uses an M5x0.8 port and fixed TPU bumper pads to soften stroke-end impact without adjustable cushioning. Because this SKU lacks a magnet, it cannot host CMSG or DMSG sensors; you would need the -S variant for position detection. The Ø8 body conforms to ISO 6432 mounting dimensions, dropping directly into standard mini-cylinder brackets.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X5CA Is Used
Micro-Clamp Actuation
Provides a 5 mm pinpoint push for securing delicate electronic wafers during PCB routing without overwhelming the fixture.
Small Part Ejection
Uses its 25.1 N thrust to kick tiny plastic mouldings out of a sub-gram machining cavity on cue.
Pivoted Gate Deflection
Leverages the CA clevis to briefly swing a lightweight diverter flap inside a small-bore sorting chute.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X5CA the Right Cylinder?
When sizing this 8 mm bore, stepping up to the Ø10 model increases your 0.5 MPa push force to 39.3 N if the 25.1 N here is insufficient, though there is no smaller AirTAC MI bore below this. The 5 mm stroke is ideal for micro-clamping, but verify your side-load geometry, as short strokes on a Ø4 mm rod leave little room for deflection.
The CA pivot cover suits articulated mechanisms, while LB foot or FA flange brackets offer rigid mounting. Remember that venting the air supply causes the piston to drift, as the TPU bumpers only decelerate the end of travel rather than locking the load. Add a pilot check valve if you need to hold position.
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 MI8X5CA FAQ
This 8 mm bore cylinder uses an M5x0.8 port. 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.
No, this specific SKU lacks an internal magnet, so CMSG, DMSG or EMSG switches will not function. You must specify the -S variant to enable position sensing. It uses fixed TPU bumper pads rather than an adjustable air cushion.
