About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X275SCA
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles demanding 275 mm stroke tasks. The Ø25 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. Fixed TPU bumper pads absorb the impact at stroke extremes without adding bulk.
The built-in -S piston magnet supports CMSG, DMSG and EMSG switches for position sensing, while the CA rear pivot cover simplifies clevis mounting. Plan for roughly 147 N of actual work at 0.5 MPa to ensure smooth cycling. This translates to lifting about 12.5 kg vertically with a 2:1 safety margin, helping you match the cylinder to real part weights.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X275SCA Is Used
Pallet Diverter Gate
Swings a heavy routing flap on a packaging line using the CA clevis, easily handling the 12.5 kg vertical gate mass within its safe working load.
Textile Loom Tensioner
Maintains consistent fabric tension across a 275 mm travel path, relying on the 206.1 N pull force at 0.5 MPa to keep strands taut.
Lab Sample Handler
Pushes sample trays into a testing chamber, where the stainless steel construction survives frequent wipe-downs and chemical splashes.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X275SCA the Right Cylinder?
When sizing this 245.3 N (0.5 MPa) unit, the smaller Ø20 bore provides 157.0 N, whereas stepping up to the non-ISO Ø32 yields 402.2 N. The 275 mm stroke is well within the 500 mm maximum, but at this extension you must account for rod bending and side-load limits to prevent premature seal wear. The CA back cover supplies a robust pivot point for swinging mechanisms.
Remember that venting the air supply or centering the control valve causes the piston to drift, as the TPU pads only soften the end-of-stroke impact rather than locking the rod. To suspend a load safely, integrate an external rod lock or a pilot-operated check valve. The -S magnet enables electronic or reed sensors, whereas a standard SKU cannot accept them.
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 MI25X275SCA FAQ
This Ø25 bore cylinder features a 1/8" port and an M10x1.25 male rod thread. It generates 245.3 N push and 206.1 N pull at 0.5 MPa, 343.4 N push and 288.5 N pull at 0.7 MPa, with a theoretical maximum of 50 kgf at 1.0 MPa.
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper pads only decelerate the stroke end and do not act as a brake. You must add an external rod lock or pilot check valve to hold a suspended load.
