Airtac MAC Stainless Steel Mini Air Cylinder MAC25X80SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X80SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 80mm 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 MAC25X80SCM
Round ends, riveted seams and a 25 mm stainless barrel describe the MAC25X80SCM: a double-acting mini cylinder with a variable air cushion at each end of its 80 mm stroke. Rated push is 245 N at 0.5 MPa and pull 206 N, climbing to 343 N and 288 N at 0.7 MPa; the ceiling is 50 kgf theoretical at 1.0 MPa.
The CM round-end cover bolts flat to machine plates with no adaptor hardware, and the standard built-in magnet picks up CMSG / DMSG / EMSG switches for end-of-stroke signals. Keep working force near 147 N at 0.5 MPa - about a 12 kg vertical lift at a 2:1 margin - and the grease-storing piston seal keeps the bore slick through years of cycling.

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 MAC25X80SCM Is Used
Carton stop on a cartoner infeed
The round end bolts straight to the machine frame, and the cushion eases each 3 kg carton to a halt without denting the blanks.
Tote gate on a vertical lift
Interlocks a tote lift platform moving 12 kg loads between levels; a pilot check valve keeps the gate from sagging if air pressure is lost.
Platen on a tube leak tester
Clamps 80 mm medical tubing samples on a wet test bench; the chrome-plated rod and stainless barrel resist the moisture that pits ordinary minis.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X80SCM the Right Cylinder?
Between the 20 mm bore at 157 N and the 32 mm at 402 N (both at 0.5 MPa), this 25 mm barrel is the mid pick for an 80 mm stroke. CM round-end mounting pairs with an FA flange, LB foot or SDB pivot bracket, while I or Y knuckles on the M10x1.25 rod add a pivot where the load needs one. Air ports are two 1/8"; remember that when the valve centres or air drops, the rod drifts - a pilot check valve or rod lock is what holds position.
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 MAC25X80SCM FAQ
Figures to size against: push 245.3 N and pull 206.1 N at 0.5 MPa, push 343.4 N at 0.7 MPa, and a 50 kgf theoretical maximum at 1.0 MPa. Air supply is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed range 30-800 mm/s, and the 1/8" ports feed both cushioned chambers.
No - the MAC is double acting with no internal lock, so a centred valve or lost supply lets the piston drift. For loads that must stay put, fit a pilot check valve in the line or specify a rod-lock variant, and never treat the end cushion as a brake; it only softens the last of the stroke.
