Airtac MI25~40 Stainless Steel Mini Cylinder MI25X270SCA
The AirTAC Airtac MI25~40 Stainless Steel Mini Cylinder MI25X270SCA is a genuine double acting round-body mini air cylinder with a Ø25mm bore and 270mm 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 MI25X270SCA
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles demanding actuation with a 270 mm stroke. The Ø25 mm bore uses a 1/8" port and an M10x1.25 male rod thread. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. The built-in magnet (-S) supports CMSG, DMSG, and EMSG switches for position sensing.
Because it conforms to ISO 6432 mounting dimensions, this unit 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. For vertical moves, that same 245.3 N output lifts about 12.5 kg safely when applying a 2:1 factor. Fixed TPU bumper pads absorb the impact at stroke end, and the rear CA pivot cover accommodates articulated rod-end loads.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X270SCA Is Used
Package Diverter Gate
Actuates a routing flap on a packaging line, using the 245.3 N push force to redirect heavy cartons reliably at speed.
Pallet Stacking Pusher
The 270 mm stroke extends to push layered products onto a pallet, while the CA clevis accommodates the shifting geometry of the transfer arm.
Lab Sample Ejector
Stainless construction withstands daily washdowns in pharmaceutical labs, ejecting processed sample trays with precise DMSG sensor feedback.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X270SCA the Right Cylinder?
When sizing this 270 mm stroke unit, verify your load against the 245.3 N push capacity at 0.5 MPa. If you need less force, the Ø20 bore provides 157.0 N; stepping up to the Ø32 yields 402.2 N. The 270 mm extension demands attention to side loading, as long strokes increase the risk of rod bending—ensure rigid guidance for the payload. The included -S magnet enables CMSG, DMSG, or EMSG sensors, while the CA rear clevis suits pivoting installations.
Remember that a standard double-acting cylinder drifts when air pressure is removed or the valve centers. The TPU bumpers only soften the end-of-stroke impact and will not function as a brake. If your application requires the load to stay put during an air loss event, 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 MI25X270SCA FAQ
At 0.5 MPa it provides 245.3 N push and 206.1 N pull. At 0.7 MPa it delivers 343.4 N push and 288.5 N pull. The theoretical maximum force is 50 kgf at 1.0 MPa. This Ø25 mm bore cylinder uses a 1/8" air port and an M10x1.25 male rod thread.
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper pads only decelerate the rod near the stroke end; they do not act as a lock. You must add an external rod lock or pilot check valve to hold a suspended load.
