About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X110SCA
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles robust linear motion tasks. The riveted barrel and Ø10 mm piston rod shrug off mild corrosion, making it far superior to painted alternatives in damp or washdown settings. A built-in piston magnet allows seamless integration with CMSG, DMSG, or EMSG switches for position sensing.
Featuring a 110 mm stroke and a CA pivot clevis back cover, it drops directly into standard ISO 6432 mini-cylinder mounting dimensions for straightforward design swaps. The 1/8" port feeds air efficiently, while fixed TPU bumper pads absorb end-of-stroke impacts. Plan for roughly 147 N of actual work at 0.5 MPa, which means it can safely lift about 12.5 kg vertically against gravity.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X110SCA Is Used
Package Diverter Gate
Swings a sorting flap on a packaging line using the CA pivot cover, relying on the 245.3 N push force to redirect heavy cartons reliably.
Pouch Sealing Press
Closes a heated sealing jaw for 110 mm of travel, where the stainless build withstands occasional washdown and the fixed TPU pads soften the final impact.
Component Ejector
Pushes machined metal parts out of a fixture, safely lifting components up to 12.5 kg vertically before the mechanism cycles back.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X110SCA the Right Cylinder?
When sizing this 25 mm bore, stepping down to a 20 mm bore drops the 0.5 MPa push force to 157.0 N, whereas a 32 mm bore jumps to 402.2 N. If your process loses air or the valve centers, the piston will drift and drop the load, as the TPU bumpers only decelerate the stroke end without acting as a brake; incorporate a pilot-operated check valve or external rod lock for strict position holding. The CA rear clevis is ideal for pivoting loads, and the -S magnet enables reed or electronic sensors.
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 MI25X110SCA 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 inch.
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper pads only decelerate the rod near the stroke end and do not function as a locking brake. You must add an external rod lock or pilot check valve to hold a load securely.
