Airtac MI25~40 Stainless Steel Mini Cylinder MI25X75R
The AirTAC Airtac MI25~40 Stainless Steel Mini Cylinder MI25X75R is a genuine double acting round-body mini air cylinder with a Ø25mm bore and 75mm 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 MI25X75R
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles robust linear motion tasks. The Ø25 mm bore uses a 1/8" port and an M10x1.25 male rod thread, while the rear R cover features an axial-in port orientation to simplify plumbing in tight layouts. Its riveted stainless barrel and rod naturally resist mild corrosion, offering a genuine advantage over painted alternatives in damp or washdown environments.
Because it conforms to ISO 6432 mounting dimensions, the body drops directly into standard mini-cylinder brackets and clevises. Plan for a safe working load of roughly 147 N (about 60% of the 0.5 MPa rating) to account for friction, or expect it to lift about 12.5 kg vertically with a 2:1 safety margin. Fixed TPU bumper pads absorb the stroke-end impact, and since this specific SKU lacks the -S magnet, it cannot host CMSG, DMSG or EMSG reed switches.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X75R Is Used
Package Diverter Gate
Actuates a routing flap on a packaging line, using the 245.3 N push force to deflect medium-weight cartons at high speed without buckling.
Pallet Stopping Arm
Deploys the 75 mm stroke to halt pallets at a strapping station, where the stainless build withstands occasional dust and moisture.
Press Ejector Mechanism
Kicks stamped metal parts out of a small press bed, relying on the rear R axial port to keep air lines clear of the tooling.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X75R the Right Cylinder?
When sizing this 245.3 N (at 0.5 MPa) unit, step down to a Ø20 bore if your application only requires 157.0 N of push force, or move up to a Ø32 bore for 402.2 N when heavier payloads are involved. The 75 mm stroke sits well within the 500 mm maximum, keeping rod bending stress low. If your mechanism must maintain its vertical position during an air loss or valve centre state, note that the piston will drift; the TPU pads only decelerate the end of travel and act as neither a brake nor a lock. You must fit an external rod lock or a pilot-operated check valve for secure load holding. To add position sensing, select the -S magnet version instead, as this base configuration cannot accept a sensor.
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 MI25X75R FAQ
At 0.5 MPa it provides 245.3 N push and 206.1 N pull. At 0.7 MPa it yields 343.4 N push and 288.5 N pull, with a theoretical maximum of 50 kgf at 1.0 MPa. The air port is 1/8" and the male rod thread is M10x1.25.
Yes, the Ø25 bore uses the ISO 6432 mounting interface for easy bracket compatibility. However, this specific SKU lacks a magnet, so it cannot accept CMSG, DMSG or EMSG switches; you must order the -S variant for position sensing.
