Airtac MAC Stainless Steel Mini Air Cylinder MAC25X175SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X175SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 175mm stroke, 1/8" air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service. A variable air cushion at both ends lets you tune end-of-stroke deceleration on site.

About the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X175SU
AirTAC built the MAC25X175SU around a stainless round barrel rolled onto aluminium covers, with a hard-chrome plated 10 mm rod that resists scoring over long 175 mm travels. Double acting with a variable air cushion at each end, it pushes 245.3 N at 0.5 MPa, which lifts about 12 kg vertically once you keep a 2:1 margin.
The cushion is adjustable: back the needle screws off on first run, then close them gradually until end-of-stroke shock disappears. A magnet is built into the piston as standard, so CMSG, DMSG and EMSG switches mount without any special-order piston. Operating range is 0.15-1.0 MPa (22-145 psi) and the fluid is air filtered to 40 um.

Specifications follow the official AirTAC MA-series datasheet. Barrel: stainless-steel tube (round-body, riveted rolling-packed construction); piston rod: carbon steel with 20µm hard-chrome plating; covers: aluminium alloy. Thread options: PT (blank) / G / NPT. Every MA-series cylinder ships with a built-in magnet for CMSG / DMSG / EMSG position sensors.
Theoretical Output Force (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 245 N | 206 N |
| 0.7 MPa | 344 N | 289 N |
| Max (@1.0 MPa) | 50 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X175SU Is Used
Carton push-off at a checkweigher
245 N at 0.5 MPa nudges rejected cartons off the belt within a 175 mm stroke while washdown splashes bounce off the stainless barrel.
CNC fixture clamping
Around 147 N of practical push clamps small aluminium parts in a jig; the cushion damps the clamp so nothing shifts at impact.
Chamber door actuation in test labs
The flat-end U cover bolts flush to the chamber frame, and the standard magnet feeds position signals to a CMSG switch.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X175SU the Right Cylinder?
At 245.3 N push and 206.1 N pull on a 0.5 MPa supply, the bore 25 sits between the 157 N bore 20 and the 402 N bore 32 - downsize when air is cheap, upsize when loads grow. Losing pressure does not park the rod: the piston simply drifts, so a pilot check valve or rod lock is needed for held loads. The U flat-end cover suits direct plate mounting, with FA flange, LB foot or SDB pivot brackets available, and I or Y knuckles thread onto the M10x1.25 rod. Over 175 mm, keep side loads off the 10 mm rod with external guides.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) is standard for sensors
- ✓ Back cover (CA/U/CM) & mount (FA/LB/SDB)
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 On first run, back off the cushion screws and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MAC Stainless Steel Mini Air Cylinder MAC25X175SU FAQ
At 0.5 MPa: 245.3 N push and 206.1 N pull. At 0.7 MPa: 343.4 N push and 288.5 N pull. The theoretical maximum is 50 kgf at 1.0 MPa. Proof pressure is 1.5 MPa (215 psi) and the working band is 0.15-1.0 MPa (22-145 psi).
The high-precision stainless tube and hard-chrome plated carbon-steel rod shrug off mild corrosion, so the cylinder handles damp workshops, outdoor gates and splash zones that ruin painted-steel minis. The heterogeneous piston seal also stores grease for longer seal life.
