About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X450SCM
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles demanding linear motion tasks. The Ø25 mm bore operates on a 1/8" port, and the extended 450 mm stroke falls well within the 500 mm standard limit for this size. Its riveted stainless barrel and rod resist mild corrosion, making it highly suitable for damp production areas where painted steel quickly degrades. The built-in piston magnet (-S) directly supports CMSG, DMSG and EMSG reed or electronic switches for precise end-of-stroke detection.
Because the rated output rarely translates perfectly to real-world friction, plan for a safe working load of roughly 147 N (about 60 percent of the 0.5 MPa push figure). In vertical lifting setups, this equates to hoisting approximately 12.5 kg with a 2:1 safety margin. The CM round end back cover provides a clean rear profile, while fixed TPU bumper pads absorb the impact at stroke extremes to protect the mechanism.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X450SCM Is Used
Diverting Gate Actuation
Pushes sorting flaps on packaging lines with 245.3 N at 0.5 MPa, utilizing the 450 mm stroke to reach across a wide conveyor belt.
Vertical Carton Lifting
Hoists lightweight cardboard cartons weighing up to 12.5 kg in damp warehouse environments, relying on the stainless rod to resist washdown corrosion.
Textile Loom Tensioning
Maintains tension on fabric threads during automated weaving, using the CM round end cover and standard ISO 6432 mounting dimensions for easy bracket integration.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X450SCM the Right Cylinder?
When sizing this unit, verify if the 245.3 N push at 0.5 MPa offers enough headroom, or step down to a Ø20 bore that provides 157.0 N. If your application requires more power, the larger Ø32 bore generates 402.2 N. The 450 mm stroke demands careful alignment to prevent rod bending and premature seal wear from side loads. This SKU includes the -S magnet for position sensing, but remember that a standard cylinder drifts when air pressure drops or the valve is centered; the TPU bumpers only decelerate the end of the stroke and will not lock the load. To maintain vertical position during an outage, 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 MI25X450SCM FAQ
This Ø25 mm bore model features a 1/8" port and a male M10x1.25 rod thread. 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.
This cylinder uses fixed TPU bumper pads to decelerate the stroke end, not an adjustable air cushion (which requires the MIC variant). However, the -S suffix indicates a built-in magnet, allowing you to mount CMSG, DMSG or EMSG electronic switches directly onto the stainless-steel round body for position detection.
