Airtac MI25~40 Stainless Steel Mini Cylinder MI25X50CM
The AirTAC Airtac MI25~40 Stainless Steel Mini Cylinder MI25X50CM is a genuine double acting round-body mini air cylinder with a Ø25mm bore and 50mm 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 MI25X50CM
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 Ø25 mm bore uses a 1/8" port and an M10x1.25 male rod thread. Its stainless barrel and rod naturally resist mild corrosion, giving it a real edge over painted-steel alternatives in damp or washdown environments. The riveted construction keeps the unit compact, while fixed TPU bumper pads absorb the impact at stroke extremes.
Because the 245.3 N rating is theoretical, plan for a safe working load of roughly 147 N of actual work at 0.5 MPa. For vertical lifting, that translates to hoisting about 12.5 kg safely with a 2:1 margin. This specific SKU features a CM round end cover and ships without a magnet, meaning it cannot host CMSG, DMSG or EMSG sensors; you would need the -S variant for position detection.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X50CM Is Used
Package Diverting Gate
Actuates a routing flap on a packaging line, using its 245.3 N push force to swiftly redirect medium-weight cartons without stalling.
Vertical Parts Press
Pushes a light-duty stamping die downward, safely delivering around 147 N of actual working force to seat small components.
Bin Lid Actuation
Lifts and lowers a heavy stainless-steel hopper lid, easily handling the 12.5 kg vertical load with a safe 2:1 lifting margin.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X50CM the Right Cylinder?
When sizing this actuator, compare it against its neighbours: a Ø20 bore provides 157.0 N of push at 0.5 MPa, while stepping up to a Ø32 yields 402.2 N. This Ø25 model hits a sweet spot for medium-force tasks. Keep in mind that a plain double-acting cylinder drifts if air pressure drops or the valve is centred—the TPU bumper only softens the end of travel and acts as neither a brake nor a lock. To suspend a load safely mid-stroke, fit an external rod lock or a pilot-operated check valve.
The CM round end cover dictates a specific rear mounting and port orientation. You can pair the body with LB foot brackets, FA flanges, SDB pivot blocks, or TC trunnions. Since this exact SKU lacks the internal magnet, it is unsuitable for magnetic position sensing. If your sequencing requires switches, select the -S magnet version and combine it with CMSG, DMSG or EMSG sensors.
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 MI25X50CM 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 force of 50 kgf at 1.0 MPa.
Yes, the Ø25 bore uses the ISO 6432 mounting interface, so it drops directly into standard mini-cylinder clevises and brackets. However, because this specific SKU lacks an internal magnet, it cannot accept CMSG, DMSG or EMSG sensors; you must specify the -S variant for position detection.
