Airtac MI25~40 Stainless Steel Mini Cylinder MI25X500SCM
The AirTAC Airtac MI25~40 Stainless Steel Mini Cylinder MI25X500SCM is a genuine double acting round-body mini air cylinder with a Ø25mm bore and 500mm stroke, 1/8" air ports and a stainless-steel barrel and rod for mildly corrosive environments. Its ISO 6432 mounting interface makes it a compact drop-in for standard mini-cylinder fixtures.

About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X500SCM
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles long 500 mm strokes with ease. The Ø25 mm bore uses a 1/8" port and an M10x1.25 male rod thread. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. The riveted construction keeps the body compact while fixed TPU bumper pads absorb impact at the stroke ends.
Because it carries the -S suffix, a built-in magnet enables CMSG, DMSG or EMSG reed and electronic switches for position sensing. The CM round end back cover neatly tucks the rear port away for tight layouts. For practical sizing, 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 MI25X500SCM Is Used
Packaging Line Diverter
Pushes heavy cartons across a transfer lane using the full 500 mm travel, relying on the 245.3 N thrust to overcome side friction without stalling.
Vertical Material Descender
Lowers lightweight jigs or fixtures down a 500 mm path, where the stainless construction prevents mild corrosion from ambient humidity.
Palletiser Stop Gate
Acts as a pneumatic stop for incoming pallets, using the CM round end cover to keep the rear port orientation tidy within the cell framework.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X500SCM the Right Cylinder?
This 500 mm stroke sits at the maximum standard limit for the Ø25 bore, so verify your guiding structure to prevent rod bending under long-travel side loads. If you need less push, the neighbouring Ø20 bore yields 157.0 N at 0.5 MPa; stepping up to the non-ISO Ø32 bore provides 402.2 N. The ISO 6432 mounting interface on this unit drops directly into standard mini-cylinder brackets and clevises.
The fixed TPU bumpers only decelerate the piston near the end of travel; they do not act as a brake. If air pressure drops or the valve centres, the rod will drift, so fit an external rod lock or pilot-operated check valve to hold a suspended load safely.
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 MI25X500SCM 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, allowing you to mount CMSG, DMSG or EMSG switches directly onto the body. For impact absorption, it relies on fixed TPU bumper pads that decelerate the stroke end; it does not feature an adjustable air cushion.
