Airtac MI25~40 Stainless Steel Mini Cylinder MI25X5SCA
The AirTAC Airtac MI25~40 Stainless Steel Mini Cylinder MI25X5SCA is a genuine double acting round-body mini air cylinder with a Ø25mm bore and 5mm 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 MI25X5SCA
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles robust actuation tasks. The Ø25 bore conforms to ISO 6432 mounting dimensions, dropping directly into standard mini-cylinder brackets and clevises for straightforward spares replacement. Its stainless barrel and rod resist mild corrosion, offering a real advantage over painted alternatives in damp or washdown environments. An integrated piston magnet allows fitment of CMSG, DMSG or EMSG switches for position sensing.
For practical sizing, plan for roughly 147 N of usable work at 0.5 MPa, which translates to lifting about 12.5 kg vertically with a 2:1 safety margin. The 5 mm stroke is exceptionally short, relying on fixed TPU bumper pads to decelerate the impact at the stroke end. Air enters via 1/8" ports, and the CA rear pivot cover provides a clevis mount for articulating linkages.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X5SCA Is Used
Clamping Short Parts
Uses the 245.3 N thrust to grip small metal components in an automated machining centre before a cutting cycle begins.
Carton Flap Folding
Articulates via the CA clevis to tuck packaging flaps on a fast-moving conveyor, relying on the 5 mm stroke for rapid cycling.
Valve Actuation
Pivots a diverter valve in a food-grade washdown zone, where the stainless rod and barrel prevent mild corrosion from moisture.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X5SCA the Right Cylinder?
When sizing this unit, the Ø20 bore provides 157 N of push at 0.5 MPa for lighter duties, while stepping up to the Ø32 yields 402.2 N if your application demands greater thrust. Because the 5 mm stroke is so brief, side-load risks are minimal, but ensure the CA clevis pivot aligns properly with your linkage to avoid binding. The integrated magnet (-S) is essential if your control system requires CMSG, DMSG or EMSG sensor feedback. Remember that venting or losing air supply will cause the piston to drift, as the TPU bumpers only soften the end-of-stroke impact rather than locking the rod; add an external pilot check valve if you need to suspend a load safely.
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 MI25X5SCA 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. The air port size is 1/8".
No, the piston will drift if air pressure is lost or the valve is centred. The fixed TPU bumper pads only decelerate the stroke end and do not act as a brake. You must use an external rod lock or pilot-operated check valve to hold a load safely.
