Airtac MI25~40 Stainless Steel Mini Cylinder MI25X15SCM
The AirTAC Airtac MI25~40 Stainless Steel Mini Cylinder MI25X15SCM is a genuine double acting round-body mini air cylinder with a Ø25mm bore and 15mm 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 MI25X15SCM
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles short 15 mm strokes with precision. The Ø25 bore uses a 1/8" port and an M10x1.25 male rod thread. Its riveted stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments. The built-in piston magnet (-S) directly supports CMSG, DMSG, and EMSG switches for position sensing.
For practical sizing, plan for roughly 147 N of actual work at 0.5 MPa, which safely lifts about 12.5 kg vertically with a 2:1 margin. The CM round end cover provides a clean rear profile for tight spaces. Fixed TPU bumper pads absorb the impact at stroke extremes, and because it conforms to ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder brackets and clevises.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X15SCM Is Used
Short-Stroke Clamping
Ideal for holding aluminium extrusions in place during CNC machining operations using its 245.3 N push force within a tight 15 mm travel.
Carton Flap Folding
The stainless build withstands humid packing lines, actuating rapidly to fold corrugated cardboard flaps prior to sealing.
Part Diverter Gate
Uses the CM round end and ISO 6432 mounts to fit neatly into conveyor frames, deflecting small routed parts at high speeds.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X15SCM the Right Cylinder?
When sizing this 15 mm stroke unit, verify if the adjacent Ø20 bore (157.0 N push @0.5 MPa) is sufficient, or step up to the Ø32 bore (402.2 N push @0.5 MPa) if your load requires more authority. This SKU includes the -S magnet for CMSG/DMSG/EMSG sensors and the CM round end cover. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion blocks.
Remember that a plain double-acting cylinder drifts when air is removed or a valve is centred; the TPU bumpers only soften the stroke end rather than locking the rod. To suspend a load safely, integrate an external rod lock or a pilot-operated check valve into your circuit. Operating speed ranges from 30-800 mm/s.
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 MI25X15SCM FAQ
This Ø25 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 piston will drift if air is lost or the valve is centred. The fixed TPU bumper pads only decelerate the stroke end and do not act as a brake. To maintain vertical position, you must fit an external rod lock or pilot check valve.
