About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X180SCA
Generating 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles robust 180 mm linear motion tasks. The Ø25 mm bore uses a 1/8 inch air 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 piston magnet (-S) supports CMSG, DMSG and EMSG switches for position sensing.
For practical sizing, plan for roughly 147 N of actual work at 0.5 MPa, which safely lifts about 12.5 kg vertically with a 2:1 margin. The CA rear pivot cover provides a clevis mount for angular alignment. Fixed TPU bumper pads decelerate the stroke end without offering adjustable cushioning, and the ISO 6432 mounting interface ensures compatibility with standard mini-cylinder brackets.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X180SCA Is Used
Package Diverting Arm
Swings on its CA clevis to push 12 kg cartons off a packaging line using the 245.3 N thrust at 0.5 MPa.
Textile Loom Tensioner
Uses the 180 mm stroke to position guide rollers in humid environments, relying on the stainless rod to prevent mild corrosion.
Pallet Gate Actuator
Extends to open safety gates on loading docks, with the -S magnet triggering DMSG sensors to confirm gate position.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X180SCA the Right Cylinder?
If you need less push, the Ø20 bore yields 157.0 N at 0.5 MPa, while stepping up to the Ø32 bore provides 402.2 N for heavier loads. This CA-clevis model suits pivoting loads, but remember the piston will drift if air pressure drops, as the TPU pads only soften impact rather than locking the rod. For secure holding, add an external rod lock or pilot check valve. The 180 mm stroke is well within the 500 mm maximum, though side loading should be minimized to prevent rod bending.
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 MI25X180SCA FAQ
At 0.5 MPa it pushes 245.3 N and pulls 206.1 N. At 0.7 MPa it pushes 343.4 N and pulls 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa. The air port is 1/8 inch.
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. Use an external rod lock or pilot check valve for load holding.
