Airtac MI25~40 Stainless Steel Mini Cylinder MI25X75SCATC
The AirTAC Airtac MI25~40 Stainless Steel Mini Cylinder MI25X75SCATC 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 MI25X75SCATC
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles robust actuation with a 75 mm stroke. The Ø25 barrel and Ø10 rod resist mild corrosion and washdown, giving it a real edge over painted alternatives in damp environments. Because the bore falls within the Ø8-Ø25 range, it uses the ISO 6432 mounting interface, dropping directly into standard mini-cylinder brackets and clevises. The riveted construction keeps the body compact, while fixed TPU bumper pads absorb the impact at stroke extremes without offering adjustable cushioning.
For practical sizing, plan for roughly 147 N of real work at 0.5 MPa, which safely lifts about 12.5 kg vertically with a 2:1 margin. The built-in -S magnet supports CMSG, DMSG and EMSG switches for position sensing. Air routes through 1/8" ports, and the unit includes a CA pivot clevis back cover alongside a TC trunnion mount for complex articulation.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X75SCATC Is Used
Package Diverter Gate
Swings a sorting flap on a packaging line using the 245 N push force and CA pivot clevis to redirect boxes weighing up to 12 kg.
Textile Loom Tensioner
Adjusts yarn tension arms in humid textile facilities where the stainless steel barrel prevents mild corrosion and ensures reliable 75 mm travel.
Pallet Wrapper Film Arm
Actuates the film carriage release mechanism on stretch wrappers, using the TC trunnion to accommodate the pivot arc during the wrap cycle.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X75SCATC the Right Cylinder?
When sizing this bore, stepping down to a Ø20 MI drops the 0.5 MPa push force to 157 N, whereas moving up to a Ø32 increases it to 402 N. Choose this Ø25 model when your load requires that middle ground of 245 N. The included TC trunnion and CA rear clevis suit pivoting loads, but remember a plain cylinder drifts if air pressure is lost or the valve is centred. The fixed TPU bumpers only decelerate the stroke end; they will not hold the load. For strict position holding, specify an external rod lock or a pilot-operated check valve.
With a 75 mm stroke, side-load and rod-bending stresses remain moderate, but always ensure the front pivot and rear clevis are aligned to prevent premature seal wear. The -S magnet is essential if your control system needs CMSG, DMSG or EMSG reed or electronic sensors to confirm end-of-stroke positions.
Quick checklist
- ✓ Required force at your working pressure

- ✓ 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 MI25X75SCATC 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. The air ports are 1/8" and the male rod thread is M10x1.25.
No, a plain MI cylinder drifts when air is lost or the valve is centred. The fixed TPU bumper pads only decelerate the piston near the stroke end; they do not act as a lock or brake. To hold a suspended load, use an external rod lock or pilot check valve.
