Airtac MI25~40 Stainless Steel Mini Cylinder MI25X700SU
The AirTAC Airtac MI25~40 Stainless Steel Mini Cylinder MI25X700SU is a genuine double acting round-body mini air cylinder with a Ø25mm bore and 700mm 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 MI25X700SU
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 700 mm stroke is a non-standard, made-to-order length for the Ø25 bore, extending well past the 500 mm catalogue maximum to suit long-reach mechanisms. Its stainless barrel and rod shrug off mild corrosion, giving a real advantage in damp or washdown environments over painted alternatives. With a 1/8" port and M10x1.25 male rod thread, it integrates smoothly into existing pneumatic setups.
The U back cover provides a 90-degree mounting orientation, while the ISO 6432 mounting interface ensures compatibility with standard mini-cylinder brackets and clevises. Fixed TPU bumper pads absorb the impact at stroke extremes without offering adjustable cushioning. Plan for a safe working load of roughly 147 N (about 60% of the 0.5 MPa rating), which translates to lifting around 12.5 kg vertically with a 2:1 safety margin. Because this SKU includes the -S magnet, it supports CMSG, DMSG, and EMSG position switches.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X700SU Is Used
Long-Reach Diverters
Pushes packages across transfer plates using the extended 700 mm stroke, relying on the 245.3 N push force to overcome sliding friction.
Vertical Material Gates
Actuates tall discharge hoppers where the stainless build resists humid ambient conditions and the U cover allows a 90-degree pivot mount.
Textile Beam Indexing
Shifts heavy fabric beams laterally, utilizing the CMSG sensors enabled by the -S magnet to confirm full extension at 700 mm.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X700SU the Right Cylinder?
When sizing this actuator, the neighbouring Ø20 bore provides 157.0 N of push at 0.5 MPa, whereas stepping up to the Ø32 yields 402.2 N. This 25 mm model sits comfortably in the middle for medium-force tasks. Remember that venting the air or centering the valve causes the piston to drift; the TPU bumpers only soften the end-of-stroke impact and will not function as a brake. For suspended loads, install an external rod lock or a pilot-operated check valve. The U-style back cover dictates a 90-degree rear pivot, so verify your geometry accommodates this along with the lengthy 700 mm rod extension, which requires careful alignment to prevent side-loading and rod bending.
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 MI25X700SU FAQ
At 0.5 MPa it provides 245.3 N push and 206.1 N pull. At 0.7 MPa it provides 343.4 N push and 288.5 N pull. The theoretical maximum force is 50 kgf at 1.0 MPa, and the air port size is 1/8".
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper pads only decelerate the stroke end and do not act as a lock. You must use an external rod lock or pilot check valve to hold a suspended load.
