About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X450SCA
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 Ø25 mm bore uses a 1/8" port and an M10x1.25 male rod thread. Because the stainless barrel and rod resist mild corrosion and washdown, it outlasts painted-steel alternatives in damp or food-industry environments. The built-in magnet (-S) directly supports CMSG, DMSG and EMSG switches for precise end-of-stroke detection.
For practical sizing, plan for roughly 147 N of real work at 0.5 MPa, which safely lifts about 12.5 kg vertically with a 2:1 margin. The 450 mm stroke falls within the 500 mm standard limit, while the CA rear pivot cover accommodates clevis mounting. Fixed TPU bumper pads absorb the impact at stroke ends, decelerating the motion smoothly without the complexity of an adjustable cushion.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X450SCA Is Used
Pivot Diverter Gate
Uses the CA clevis mount to swing a heavy sorting flap on a packaging line, utilising the 245.3 N thrust to push bulky cardboard cartons reliably.
Vertical Parts Lift
Raises lightweight metal fixtures through the 450 mm stroke, safely lifting components weighing up to 12.5 kg in an automated assembly cell.
Lab Washdown Station
The stainless construction survives mildly corrosive cleaning agents, actuating a rinse nozzle bracket in a food processing test laboratory.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X450SCA the Right Cylinder?
When sizing this 245.3 N (0.5 MPa) unit, dropping down to the Ø20 bore reduces thrust to 157.0 N, whereas stepping up to the non-ISO Ø32 bore yields 402.2 N. If your application requires variable shock absorption at high speeds, consider the MIC cushioned variant instead of relying on the standard fixed TPU bumpers. The CA back cover provides a rear pivot point for angular movement.
A 450 mm stroke on a Ø25 bore demands careful alignment to prevent rod bending and premature seal wear. Furthermore, standard pneumatics drift when air is lost or a valve centres; the bumpers only soften the end stops and do not act as a brake. To suspend a load safely, integrate an external rod lock or a pilot-operated check valve into your circuit.
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 MI25X450SCA 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".
Yes, the -S suffix indicates a built-in piston magnet compatible with CMSG, DMSG and EMSG switches. The Ø25 bore adheres to ISO 6432 mini-cylinder mounting dimensions, and the CA back cover provides a pivot/clevis interface for angular mounting requirements.
