Airtac MI25~40 Stainless Steel Mini Cylinder MI25X250SCM
The AirTAC Airtac MI25~40 Stainless Steel Mini Cylinder MI25X250SCM is a genuine double acting round-body mini air cylinder with a Ø25mm bore and 250mm 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 MI25X250SCM
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles substantial work for a 25 mm bore. The 250 mm stroke operates at 30-800 mm/s, fed by a 1/8" port. Its stainless barrel and piston rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments.
The integrated piston magnet supports CMSG, DMSG, and EMSG switches for position sensing. Because it conforms to ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder brackets and clevises. For practical sizing, plan for about 147 N of actual work at 0.5 MPa, which means it lifts roughly 12.5 kg vertically with a 2:1 safety margin.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X250SCM Is Used
Package Diverting Gate
Actuates a routing flap on a packaging line, using the 245.3 N push force to redirect heavy cartons reliably at high cycle speeds.
Vertical Parts Lift
Raises lightweight jigs or components 250 mm; the 12.5 kg safe vertical lift capacity handles the payload without over-stressing the rod.
Washdown Valve Trigger
Stainless construction survives humid food-processing zones, repeatedly triggering a diverter valve where painted cylinders would corrode.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X250SCM the Right Cylinder?
When sizing this 25 mm bore, the smaller Ø20 generates 157.0 N of push at 0.5 MPa, while the larger Ø32 provides 402.2 N, giving you clear scaling if the load shifts. The CM round end back cover dictates the rear mounting and port orientation, so verify your pivot geometry matches this style. For position feedback, the -S magnet pairs directly with CMSG, DMSG, or EMSG sensors.
A 250 mm stroke demands attention to side loading; ensure your front mounting guides the load to prevent rod bending. Remember that venting the air causes the piston to drift, as the fixed TPU bumper pads only soften the stroke-end impact rather than locking the load. To hold a vertical position securely, add 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 MI25X250SCM FAQ
This 25 mm bore cylinder features a 1/8" port and an M10x1.25 male rod thread. It generates 245.3 N push and 206.1 N pull at 0.5 MPa, 343.4 N push and 288.5 N pull at 0.7 MPa, with a theoretical maximum of 50 kgf at 1.0 MPa.
No, the fixed TPU bumper pads only decelerate the stroke end and are not an adjustable air cushion. If air is lost, the piston drifts; to hold a vertical load, you must use an external rod lock or pilot check valve. The CM round end and ISO 6432 dimensions simplify mounting.
