About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X35SCA
Generating 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles substantial work in compact spaces. The integrated piston magnet (-S) directly supports CMSG, DMSG and EMSG reed or electronic switches for precise end-of-stroke detection. Its 1/8" port and M10x1.25 male rod thread provide robust pneumatic and mechanical interfaces for heavier tooling.
The rolled stainless barrel and rod resist mild corrosion, offering a real advantage over painted alternatives in damp or washdown environments. Fixed TPU bumper pads absorb impact energy at the stroke extremes. Because it yields about 12.5 kgf at 0.5 MPa, you can plan for a safe vertical lift of roughly 6 kg with a 2:1 margin, while the CA rear pivot cover allows straightforward clevis mounting.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X35SCA Is Used
Clamping Heavy Billets
Secures steel billets on a CNC milling fixture using the 245.3 N push force at 0.5 MPa, with the CA clevis accommodating slight misalignment.
Carton Flap Folding
Folds heavy corrugated cardboard flaps on a washdown-capable packaging line, where the stainless rod shrugs off daily moisture.
Pallet Diverter Gate
Actuates a routing gate on a logistics conveyor, relying on the built-in magnet and DMSG sensor to confirm gate position to the PLC.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X35SCA the Right Cylinder?
When sizing this 25 mm bore, compare it against its neighbours: a 20 mm bore gives 157.0 N push at 0.5 MPa, while stepping up to a 32 mm bore provides 402.2 N. This model fits neatly in the middle for medium-force clamping. The 35 mm stroke is well within the 500 mm maximum, keeping the rod short and highly resistant to bending under side loads. The CA back cover supplies a pivot point, but remember that venting or losing air pressure will cause the piston to drift; the bumpers only soften the end of travel rather than locking the rod, so fit an external pilot check valve if you need to suspend a load safely.
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 MI25X35SCA FAQ
This 25 mm 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, it relies on fixed TPU bumper pads to decelerate the piston at the stroke ends. The stainless-steel round body conforms to ISO 6432 mounting dimensions for easy bracket interchange, and the -S suffix means it contains a magnet for CMSG, DMSG or EMSG sensors.
