Airtac MI25~40 Stainless Steel Mini Cylinder MI25X600SU
The AirTAC Airtac MI25~40 Stainless Steel Mini Cylinder MI25X600SU is a genuine double acting round-body mini air cylinder with a Ø25mm bore and 600mm 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 MI25X600SU
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles demanding linear motion. The 600 mm stroke is a made-to-order length that exceeds the standard 500 mm maximum for this bore, engineered for extended travel. A built-in piston magnet (-S) supports CMSG, DMSG and EMSG switches for position sensing, while the U-type back cover provides a 90-degree port and mounting orientation.
The stainless-steel barrel and Ø10 mm rod shrug off mild corrosion and washdown environments better than painted alternatives. With a 1/8" port and M10x1.25 male rod thread, it integrates smoothly into existing setups. Plan for roughly 147 N of actual work at 0.5 MPa, which translates to lifting about 12.5 kg vertically with a safe 2:1 margin. Fixed TPU bumper pads absorb stroke-end impact to protect the mechanism.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X600SU Is Used
Extended-Reach Diverters
Pushes packages across wider transfer lines using the 600 mm stroke, applying 245.3 N at 0.5 MPa to overcome side friction.
Vertical Parts Lift
Raises lightweight tote bins up to 12.5 kg through a 2:1 safety margin, relying on the stainless rod for humid storage environments.
Film Roll Feed
Actuates material feed arms over long distances, using the U-type 90-degree back cover to fit compact machinery frames.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X600SU the Right Cylinder?
Choosing this bore means sizing against its neighbours: a Ø20 generates 157 N push while a Ø32 yields 402 N, both at 0.5 MPa, so the Ø25 sits comfortably in the mid-range at 245.3 N. Because the 600 mm travel exceeds the 500 mm standard stroke, carefully account for rod deflection and side loads to prevent premature seal wear. The ISO 6432 mounting interface allows this unit to drop into standard mini-cylinder brackets and clevises.
Remember that venting the air supply causes the piston to drift, as the fixed TPU pads only decelerate the end of stroke rather than locking the load. To suspend a vertical weight securely, install an external rod lock or a pilot-operated check valve. The U-type rear cover dictates a 90-degree orientation, and the integrated magnet is essential for fitting 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 MI25X600SU FAQ
At 0.5 MPa it pushes 245.3 N and pulls 206.1 N; at 0.7 MPa it pushes 343.4 N and pulls 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa. The air port size is 1/8" and the male rod thread is M10x1.25.
No, it uses fixed TPU bumper pads that decelerate the stroke end but do not provide adjustable air cushioning. Furthermore, the piston will drift if air is lost; the bumpers are not a brake, so use an external rod lock or pilot check valve to hold a suspended load.
