Airtac MAC Stainless Steel Mini Air Cylinder MAC25X125SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X125SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 125mm 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 MAC25X125SCM
With a round-end CM back cover, the MAC25X125SCM drops into clevis-style or swivelling arrangements where a flat rear face would fight the geometry. The bore 25 barrel is double acting over 125 mm and cushions at both ends via adjustable air needles. Force at 0.5 MPa is 245.3 N push and 206.1 N pull; 0.7 MPa lifts that to 343.4 N / 288.5 N, and the theoretical peak is 50 kgf at 1.0 MPa. Keep applied duty near 147 N at 0.5 MPa and the cylinder holds a healthy reserve.
The body follows the riveted MA layout - stainless round tube rolled against aluminium covers with a hard-chrome plated rod - which survives damp, dusty and lightly washed environments that corrode painted minis. Sensing needs nothing extra: the magnet is standard, so CMSG, DMSG or EMSG reed or electronic switches mount straight onto the tube. Porting is 1/8 inch, pressure range 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s.

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 MAC25X125SCM Is Used
Welding fixture turntable index
Pushes a lever linkage that rotates a small welding fixture into position, with the CM round-end cover swinging on a clevis pin through the arc.
Rinse station dosing head
Actuates a dosing head on a bottle rinsing carousel, where the stainless barrel and chrome rod handle the wet zone without corrosion worries.
CNC enclosure slide cover
Opens and closes a sliding chip-guard cover on a compact CNC mill, using the cushion to stop the door softly at each end.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X125SCM the Right Cylinder?
Between bores, a 20 mm MAC gives 157.0 N push at 0.5 MPa and a 32 mm gives 402.2 N, bracketing this 25 mm at 245.3 N - pick by load, not by habit. Should the valve centre with a load held mid-stroke, the piston will creep; spec a pilot check or rod lock rather than leaning on the cushion. The CM round end suits pivoting rear mounts; for rigid fixing stay with U, FA flange or LB foot variants. On a 125 mm stroke, add an external guide if the load presents any side force to the rod.
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 MAC25X125SCM 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. Theoretical maximum is 50 kgf at 1.0 MPa. It is double acting with a variable air cushion both ends, accepts 0.15-1.0 MPa (22-145 psi), travels 30-800 mm/s, and ports at 1/8 inch.
It replaces the standard rear cover with a rounded pivot-friendly end, so linkage and clevis mounts connect without fabricated brackets. Front-side options remain FA flange, LB foot, SDB pivot bracket and I or Y rod knuckles should the application need them.
