About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X45SCA
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 Ø25 bore operates on a 1/8" port and features a CA pivot/clevis rear cover for articulated mounting. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Because the stroke is a short 45 mm, fixed TPU bumper pads effectively absorb the end-of-travel impact without needing adjustment.
For practical sizing, plan for around 147 N of real work at 0.5 MPa, which safely lifts about 12.5 kg vertically with a 2:1 margin. The built-in piston magnet (-S) directly supports CMSG, DMSG, and EMSG reed or electronic switches. Furthermore, the unit conforms to ISO 6432 mounting dimensions, allowing it to drop directly into standard mini-cylinder brackets and clevises.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X45SCA Is Used
Package Diverter Arm
Swings a lightweight routing gate on packaging lines using the CA pivot mount, relying on the 245.3 N thrust to push parcels smoothly at 0.5 MPa.
Pallet Stopper Gate
Acts as a pneumatic stop in low-height warehouse conveyors, where the short 45 mm stroke and fixed TPU bumpers absorb repeated mechanical impacts.
Lab Sample Ejector
Ejects processed samples from a test bay, using the stainless construction to resist humid lab environments and the -S magnet to confirm ejection.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X45SCA the Right Cylinder?
When sizing this 45 mm stroke unit, compare it against neighbouring bores: a Ø20 generates 157.0 N push at 0.5 MPa, while a larger Ø32 provides 402.2 N. If your mechanism loses air or the valve centres, this plain cylinder will drift and cannot hold position; the bumpers only decelerate the stroke end rather than locking the load. For secure holding, add an external rod lock or a pilot-operated check valve. The CA rear clevis suits pivoting loads, but ensure side loading is minimized to prevent rod bending over repeated cycles.
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 MI25X45SCA 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 is 1/8".
Yes, the -S suffix means it has a built-in piston magnet for CMSG, DMSG, or EMSG switches. The cushion consists of fixed TPU bumper pads that decelerate the stroke end; it is not an adjustable air cushion.
