About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X350CA
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles substantial work within a compact footprint. The 25 mm bore uses a 1/8 inch port and a 10 mm rod, extending 350 mm to move loads. Its stainless barrel and rod resist mild corrosion, offering a real advantage over painted alternatives in damp or washdown settings. Riveted round-body construction keeps the unit light, while fixed TPU bumper pads absorb impact at the stroke ends.
Plan for roughly 147 N of actual work at 0.5 MPa, accounting for friction and efficiency losses. This translates to lifting about 12.5 kg vertically with a safe 2:1 margin. The Ø25 dimension conforms to ISO 6432 mounting interfaces, dropping directly into standard clevis brackets. Note this specific SKU lacks a magnet, so it cannot host CMSG or DMSG sensors without switching to an -S variant.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X350CA Is Used
Package Diverting Arm
Swings on a CA pivot to deflect cartons on a packaging line, using the 245.3 N push force to swing heavy goods smoothly.
Textile Loom Tensioner
Moves a guide bar through 350 mm to maintain material tension, relying on the stainless rod to withstand humid manufacturing environments.
Pallet Gate Actuator
Opens and closes a 12.5 kg safety gate on a palletizing station, utilizing the full stroke length without exceeding the safe working load.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X350CA the Right Cylinder?
When sizing this 25 mm bore, verify your force needs against its 245.3 N push and 206.1 N pull at 0.5 MPa. If your application requires less energy, the 20 mm bore provides 157.0 N push; stepping up to the 32 mm bore yields 402.2 N. The 350 mm stroke is well within the 500 mm maximum, but at this length side loads can bend the 10 mm rod—ensure proper guiding. The CA back cover provides a pivot clevis for articulated mounting, complementing LB foot and FA flange options.
Because the standard MI uses fixed TPU bumpers rather than an adjustable cushion, high-speed cycling may require the MIC variant. Furthermore, a plain cylinder drifts when air is lost or the valve centers; the bumpers only decelerate the end of stroke and act as neither a lock nor a brake. To suspend a load safely, install an external rod lock or a pilot-operated check valve.
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 MI25X350CA FAQ
This 25 mm bore cylinder features a 1/8 inch port and a 10 mm rod. It generates 245.3 N push and 206.1 N pull at 0.5 MPa, increasing to 343.4 N push and 288.5 N pull at 0.7 MPa. The theoretical maximum force is 50 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet, so it cannot support CMSG, DMSG, or EMSG magnetic switches. You would need the -S magnet variant for position sensing. It uses fixed TPU bumper pads for end-of-stroke deceleration rather than an adjustable air cushion.
