Airtac MAC Stainless Steel Mini Air Cylinder MAC25X450SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X450SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 450mm 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 MAC25X450SCM
Stainless construction is the headline of the MAC25X450SCM: a riveted round barrel in stainless steel, a 20 um hard-chrome plated carbon-steel rod, and aluminium covers sealed by rolling - a body that tolerates washdown and outdoor damp where painted minis corrode. It is double acting with variable air cushions at both ends, fed at 0.15-1.0 MPa (22-145 psi).
At 0.5 MPa the bore pushes 245 N and pulls 206 N; 0.7 MPa raises push to 343 N, and 1.0 MPa gives a 50 kgf theoretical ceiling. Treat 147 N as the realistic working force, the equivalent of hoisting about 12.5 kg vertically with margin to spare. The CM round-end back cover is fitted as delivered, and the built-in magnet accepts CMSG, DMSG and EMSG switches immediately.

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 MAC25X450SCM Is Used
Damper linkage on a paint-shop air duct
Drives a 450 mm damper arm between open and closed; the stainless body handles humid, solvent-laden shop air.
Hatch opener on a brine tank in fish processing
Lifts a hinged hatch twice a shift in a washdown zone, where the stainless barrel and chrome rod outlast painted units.
Layer pusher on a pallet stacking table
Squares each carton layer with about 147 N of working force, the variable cushion settling the push gently at each end.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X450SCM the Right Cylinder?
Step down to a 20 mm MAC for 157 N duties or up to the 32 mm bore for 402 N at 0.5 MPa; this 25 mm barrel covers the middle ground. Position holding is not part of the package - with air off or the valve centred the rod floats, so add a rod lock or pilot check valve where a load must stay put. The CM round-end cover takes pivot pins directly, while FA flange, LB foot and SDB pivot brackets plus I / Y rod knuckles handle fixed mounts. Across 450 mm of stroke, support long tooling so side loads never reach the 10 mm 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 MAC25X450SCM FAQ
The double-acting 25 mm bore produces 245.3 N push and 206.1 N pull at 0.5 MPa, 343.4 N push at 0.7 MPa, and up to 50 kgf at 1.0 MPa in theory. Air supply is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof, ports are 1/8", rod thread is M10x1.25, and rod speed spans 30-800 mm/s.
The CM round-end back cover accepts pivot pins as delivered; FA flange, LB foot and SDB pivot brackets bolt on for fixed or pivoting frames, and I or Y rod knuckles connect the 10 mm rod to your linkage. Keep the mounting square so the 450 mm stroke tracks straight.
