About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X175CM
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 25 mm bore pairs a 10 mm piston rod with a 1/8" port, while the 175 mm stroke operates at 30-800 mm/s. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings.
The riveted construction keeps the body compact, and fixed TPU bumper pads absorb the impact at stroke extremes. Because this SKU lacks the -S magnet, it cannot host CMSG or DMSG sensors. For position feedback, you would need the -S variant. Plan for roughly 147 N of actual work at 0.5 MPa, which means it can safely lift about 12.5 kg vertically with a 2:1 safety margin.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X175CM Is Used
Package Diverting Gate
Actuates a routing flap on a packaging conveyor to push parcels weighing up to 12 kg onto secondary tracks without stalling.
Textile Loom Tensioner
Maintains consistent fabric tension on an industrial weaving machine, utilizing the 245.3 N force to hold yarn guides firmly in place.
Bin Lid Actuation
Opens and closes heavy stainless-steel hopper lids in a food storage facility, where the corrosion-resistant barrel survives daily washdowns.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X175CM the Right Cylinder?
Sizing around this 245.3 N (at 0.5 MPa) unit means looking at the 20 mm bore for lighter loads, which offers 157.0 N push, or stepping up to the 32 mm bore that generates 402.2 N if your application demands more thrust. The CM round end back cover suits basic rear mounting arrangements, and you can utilize LB foot or FA flange brackets to match your frame.
Remember that a standard double-acting cylinder drifts if air pressure drops or the valve is centred; the TPU bumpers only soften the end of travel and do not function as a brake. To suspend a load safely, install an external pilot check valve or a rod lock. Also, with a 175 mm stroke, ensure your front mounting guides absorb lateral stress 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 MI25X175CM FAQ
This 25 mm bore cylinder features a 1/8" port. 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, this specific SKU does not include a magnet. To use CMSG, DMSG, or EMSG magnetic switches, you must select the -S variant of the MI series. Additionally, its ISO 6432 mounting dimensions allow it to drop directly into standard mini-cylinder brackets and clevises.
