Airtac MI25~40 Stainless Steel Mini Cylinder MI25X75CA
The AirTAC Airtac MI25~40 Stainless Steel Mini Cylinder MI25X75CA is a genuine double acting round-body mini air cylinder with a Ø25mm bore and 75mm stroke, 1/8" 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 MI25~40 Stainless Steel Mini Cylinder MI25X75CA
Delivering 245.3 N of push force at 0.5 MPa, the AirTAC MI25X75CA is a double-acting round-body mini cylinder built from a stainless-steel barrel and rod. This riveted construction shrugs off mild corrosion, giving it a real edge over painted alternatives in damp washdown zones. The Ø25 bore conforms to ISO 6432 mounting dimensions, dropping directly into standard mini-cylinder brackets and clevises.
Internally, fixed TPU bumper pads absorb the stroke-end impact to decelerate the piston smoothly. Because this specific SKU lacks the -S magnet option, it cannot host CMSG, DMSG or EMSG reed switches. For actuation, air enters via a 1/8" port, and the CA back cover provides an integrated pivot clevis for articulated rod-end loads. Plan for roughly 147 N of actual work at 0.5 MPa, which means it lifts about 12.5 kg vertically with a safe 2:1 margin.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X75CA Is Used
Pivoting Clamp Arms
Uses the CA rear clevis to swing a 12 kg machining fixture into place, utilising the 245.3 N push force to secure the part during milling.
Package Deflector Gates
Diverts medium-weight cartons on a packaging line where the stainless body survives daily washdowns better than standard aluminium extrusions.
Textile Loom Tensioning
Maintains consistent yarn tension via the 75 mm stroke, relying on the 206.1 N pull force at 0.5 MPa to keep weaving components taut.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X75CA the Right Cylinder?
Sizing the MI25X75CA means looking both ways: the smaller Ø20 bore yields 157 N of push at 0.5 MPa, while stepping up to the Ø32 bore provides 402.2 N. This 25 mm option sits perfectly in the middle for medium-force pivoting tasks. The 75 mm stroke is well within the 500 mm maximum, keeping rod bending stress low. Remember that the fixed TPU bumpers only soften the end of travel; they do not function as a brake. If your pivot arm must remain locked mid-cycle during a pressure drop, you must add an external rod lock or a pilot-operated check valve, as the piston will drift otherwise.
The CA rear clevis is designed for swinging linkages, pairing with FA flanges or TC trunnions if your frame requires a different geometry. Since this unit has no internal magnet, position sensing is impossible without switching to the -S variant.
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 MI25~40 Stainless Steel Mini Cylinder MI25X75CA FAQ
This double-acting cylinder uses a 1/8" air port and a Ø10 mm rod with an M10x1.25 male thread. It generates 245.3 N push and 206.1 N pull at 0.5 MPa, increasing to 343.4 N push and 288.5 N pull at 0.7 MPa. The theoretical maximum force is 50 kgf at 1.0 MPa.
No, this specific SKU does not include the internal magnet required for sensing. To use CMSG, DMSG or EMSG switches, you must purchase the -S variant of this stainless-steel mini cylinder. The CA back cover provides a pivot clevis for mounting.
