Airtac MAC Stainless Steel Mini Air Cylinder MAC25X145SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X145SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 145mm 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 MAC25X145SCA
Built for punchy mid-range work, the MAC25X145SCA pairs a 25 mm bore with a 145 mm stroke in a riveted round-body housing: stainless-steel barrel, hard-chrome plated rod (about 20 um) and rolled aluminium covers that shrug off washdown and damp shop air better than painted minis. Double acting with a variable air cushion at both ends, it delivers 245.3 N of push and 206.1 N of pull at 0.5 MPa, rising to 343.4 N forward at 0.7 MPa.
The CA pivot back cover bolts straight to linkage points without extra brackets, and the magnet shipped as standard lets CMSG / DMSG / EMSG switches clip on for end-of-stroke signal. Run it at 0.15-1.0 MPa (22-145 psi) and 30-800 mm/s. In practice, plan real work around 147 N - roughly six tenths of the rated push - enough to lift about 12 kg vertically with a 2:1 margin.

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 MAC25X145SCA Is Used
Packaging gate flipper
At 245.3 N push, the 145 mm stroke swings a sorting gate or reject arm across a 300 mm-wide product lane on a snack-food packaging line.
Welding jig clamp
Around 147 N of practical clamping force holds small bracketry in place on a spot-welding fixture while the CA pivot follows the clamp arm's swing.
Assembly push-off
Capped at 147 N of working force, the cylinder ejects finished bushings from an assembly nest at up to 800 mm/s, with the air cushion softening every stroke end.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X145SCA the Right Cylinder?
If 245.3 N of push at 0.5 MPa is more than the job needs, step down to the 20 mm bore (157 N); if the load fights back, the 32 mm bore gives 402.2 N at the same pressure. Keep in mind a plain MAC does not lock its rod - when the valve centres or air drops, the piston drifts, so add a rod lock or pilot check valve for held loads. The CA pivot cover suits swinging linkage; ask for FA flange, LB foot or SDB brackets if you need fixed mounting, and the built-in magnet means position sensing needs no special piston. At 145 mm stroke, keep side loads off the 10 mm rod and guide the load externally.
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 MAC25X145SCA FAQ
At 0.5 MPa it pushes 245.3 N and pulls 206.1 N; at 0.7 MPa push rises to 343.4 N and pull to 288.5 N. The theoretical ceiling at 1.0 MPa is 50 kgf. Air supply is 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s, and the 1/8" ports take standard fittings.
The CA cover gives a built-in pivot eye, so swinging linkage, gate arms and clamp levers attach directly with no extra knuckle. The 25 mm bore keeps the 145 mm stroke compact, the stainless barrel tolerates washdown, and the standard magnet accepts CMSG / DMSG / EMSG switches.
