Airtac MI25~40 Stainless Steel Mini Cylinder MI25X25SCAG
The AirTAC Airtac MI25~40 Stainless Steel Mini Cylinder MI25X25SCAG is a genuine double acting round-body mini air cylinder with a Ø25mm bore and 25mm 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 MI25X25SCAG
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles substantial work in tight spaces. The Ø25 mm bore uses a 1/8" port and an M10x1.25 male rod thread. Its riveted stainless barrel and rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Because it carries an internal magnet (-S), you can track piston position with CMSG, DMSG or EMSG switches.
The fixed TPU bumper pads absorb stroke-end impact without offering adjustable cushioning. For sizing moving masses, plan for roughly 147 N of actual work at 0.5 MPa, which translates to lifting about 12.5 kg vertically with a 2:1 safety margin. The CA rear pivot cover and G BSPP thread option tailor it directly to specific machinery layouts.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X25SCAG Is Used
Diverter Gate Actuation
Snaps a sorting flap on a packaging line with 245.3 N of push force, withstanding routine washdowns thanks to the stainless steel construction.
Short-Stroke Clamping
Secures aluminium extrusions for a CNC cutting station, using the 25 mm stroke and CA pivot mount to swing firmly into place.
Carton Lid Press
Holds a folding carton lid down for sealing, safely applying around 147 N of working force without crushing the cardboard.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X25SCAG the Right Cylinder?
When sizing this 25 mm bore, the 20 mm option steps down to 157 N of push force at 0.5 MPa, while the larger 32 mm jumps up to 402 N. Choose this model when your load sits comfortably in the middle. The short 25 mm stroke keeps the rod highly resistant to bending, but always verify side-load alignment. It uses the ISO 6432 mounting interface, so it drops directly into standard mini-cylinder brackets and clevises.
Remember that venting the air or centering the valve lets the piston drift freely, as the TPU pads only soften the end stops rather than locking the rod. For suspended loads that must stay put during pressure loss, add an external rod lock or a pilot-operated check valve. The CA clevis back cover suits pivoting articulations perfectly.
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 MI25X25SCAG FAQ
At 0.5 MPa it pushes with 245.3 N and pulls with 206.1 N. At 0.7 MPa the push is 343.4 N and pull is 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa. This 25 mm bore cylinder uses a 1/8" air port.
Yes to sensors, no to adjustable cushions. The -S suffix means it has a built-in magnet for CMSG, DMSG or EMSG switches. However, it relies on fixed TPU bumper pads to decelerate the stroke end; for adjustable air cushioning you would need the MIC variant.
