About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X50SCM
Delivering 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 riveted barrel and Ø10 mm rod shrug off mild corrosion, making it superior to painted alternatives in damp or washdown environments. Its 1/8" port and M10x1.25 male rod thread provide robust pneumatic and mechanical interfaces.
Because the 245.3 N rating leaves little margin for friction, plan for about 147 N of real work at 0.5 MPa. This translates to lifting roughly 12.5 kg vertically with a safe 2:1 factor, letting you match the cylinder to actual part weights. The built-in magnet supports CMSG, DMSG and EMSG switches for position sensing, while the round CM back cover offers versatile rear mounting. Fixed TPU bumper pads absorb stroke-end impact to protect your mechanism.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X50SCM Is Used
Package Diverter Arm
Pushes light cardboard cartons on a packaging line using the 245.3 N thrust, with the stainless build resisting humid warehouse air.
Clamping Fixture
Holds an aluminium workpiece in a CNC mill using the 206.1 N pull force, relying on the 50 mm stroke for rapid actuation.
Lab Sample Ejector
Ejects processed vials from a tester station, where the washdown-ready stainless barrel prevents chemical corrosion.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X50SCM the Right Cylinder?
When sizing this 25 mm bore, compare it directly with its neighbours: a 20 mm bore provides 157.0 N push at 0.5 MPa, while stepping up to a 32 mm bore yields 402.2 N. Choose this model when your load requires approximately 147 N of actual working force. The 50 mm stroke is well within the 500 mm maximum, keeping the rod rigid and minimizing side-load bending risks. The CM round end cover allows flexible rear pivoting or direct mounting.
Remember that a standard double-acting cylinder drifts when air is lost or the valve is centred; the TPU bumpers only decelerate the stroke end and do not function as a lock. To suspend a vertical load safely, install an external rod lock or a pilot-operated check valve. The included -S magnet enables electronic or reed switch sensing, and the body conforms to ISO 6432 mounting dimensions for standard mini-cylinder brackets.
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 MI25X50SCM 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".
Yes, the S suffix indicates a built-in piston magnet compatible with CMSG, DMSG and EMSG switches. For impact absorption, it uses fixed TPU bumper pads that decelerate the piston at stroke end; it does not have an adjustable air cushion.
