About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X70CA
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles substantial work within a compact footprint. The 25 mm bore uses a 1/8" port and an M10x1.25 male rod thread. Its stainless barrel and rod resist mild corrosion, giving it an edge over painted alternatives in damp or washdown settings. Fixed TPU bumper pads absorb stroke-end impact.
Built to ISO 6432 mounting dimensions, the body drops directly into standard mini-cylinder brackets and clevises. Plan for roughly 147 N of actual work at 0.5 MPa to maintain a safe margin, which translates to lifting about 12.5 kg vertically. This specific CA variant features a rear pivot clevis for articulated mounting.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X70CA Is Used
Package Diverting Gate
Actuates a routing flap on a packaging line, using the 245 N push force to redirect heavy cartons onto secondary tracks.
Clamp Arm Pivot
Uses the CA rear clevis to swing an arm, securing metal workpieces under a drill press despite minor coolant spray.
Vertical Parts Lift
Raises lightweight industrial totes in a vertical elevator, safely lifting components weighing up to 12.5 kg.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X70CA the Right Cylinder?
When sizing this 25 mm bore, stepping down to a 20 mm cylinder drops the 0.5 MPa push force to 157 N, while moving up to a 32 mm bore raises it to 402 N. Choose this model when your load sits closer to 245 N. The 70 mm stroke keeps the rod short, minimizing side-load bending. Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG position switches; add the -S option if you need sensing. The CA rear pivot cover suits angular movement.
Remember that the TPU bumpers only decelerate the piston near the stroke end; they do not function as a brake. If air pressure drops or the valve is centred, the rod will drift. To suspend a load safely during an outage, install an external rod lock or a pilot-operated check valve.
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 MI25X70CA FAQ
At 0.5 MPa it provides 245.3 N push and 206.1 N pull. At 0.7 MPa it provides 343.4 N push and 288.5 N pull. The theoretical maximum force is 50 kgf at 1.0 MPa. The air port size is 1/8".
No, this specific SKU does not include a magnet, so CMSG, DMSG or EMSG switches will not function. You must select the -S variant (MI25X70CA-S) to enable magnetic position sensing. The CA back cover provides a pivot mounting point.
