Airtac MAC Stainless Steel Mini Air Cylinder MAC25X175SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X175SCM 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 MAC25X175SCM
A riveted round body built from a stainless-steel barrel with a hard-chrome plated 10 mm rod, the MAC25X175SCM is a double acting mini cylinder with a variable air cushion at both ends. At 0.5 MPa it pushes with 245 N (245.3 N), so plan on roughly 147 N of real work once you keep a margin for friction and wear.
The CM round-end back cover takes a pivot pin directly, and the rolling-packed covers shrug off washdown and damp far better than painted minis. Speed runs 30-800 mm/s across 0.15-1.0 MPa (22-145 psi), and the cushion needle screws let you soften the 175 mm stroke ends so faster cycles do not hammer the covers.

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 MAC25X175SCM Is Used
Tray indexing on packaging lines
The 245 N push at 0.5 MPa indexes small food trays down a 175 mm pitch while the stainless barrel survives daily caustic washdown.
Connector staking on small assemblies
Around 147 N of usable work force crimps terminals and stakes plastic bosses without stressing a delicate fixture.
Hopper gate opening on dosing units
The CM round-end cover pins straight to the gate lever, and the variable cushion stops the 175 mm stroke from slamming at either end.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X175SCM the Right Cylinder?
If 245 N at 0.5 MPa is more than the job needs, the bore 20 MAC gives 157 N; if the load climbs, step up to bore 32 for 402 N. This 175 mm stroke sits well inside the 500 mm standard range for bore 25, so it ships as a catalogue item. The piston drifts when air is removed - it is not a position holder, so add a rod lock or pilot check valve where the load must stay put. Keep the 10 mm rod side-load free over 175 mm with external guides, and bolt on FA flange, LB foot or SDB pivot brackets as the frame allows; CMSG, DMSG or EMSG switches read the standard built-in magnet.
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 MAC25X175SCM FAQ
At 0.5 MPa it pushes 245.3 N and pulls 206.1 N; at 0.7 MPa that rises to 343.4 N push and 288.5 N pull. The theoretical ceiling at 1.0 MPa is about 50 kgf. Pressure window is 0.15-1.0 MPa (22-145 psi) and speed 30-800 mm/s.
It lets you pin the cylinder straight to a pivot or link arm without fabricating a bracket, and the stainless round barrel plus hard-chrome 10 mm rod keeps rust out of washdown or outdoor duty. The 1/8" ports come in PT, G or NPT thread.
