Airtac MAC Stainless Steel Mini Air Cylinder MAC25X10SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X10SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 10mm 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 MAC25X10SU
For pick-and-place z-axes and short clamps, the MAC25X10SU covers the gap: a 25 mm bore with just 10 mm of travel, double acting, cushioned at both ends by a variable air cushion you set with the needle screws. Extend force is 245.3 N and retract 206.1 N at 0.5 MPa; at 0.7 MPa it reaches 343.4 N push and 288.5 N pull, with roughly 50 kgf of theoretical force at the 1.0 MPa ceiling.
Derated to 147 N of honest working push at 0.5 MPa, it handles about a 12 kg vertical lift at a 2:1 margin - enough for small castings, brackets and housings. The U-shaped flat back cover sits flush against machine plates, and FA flange, LB foot or SDB pivot brackets bolt straight to the riveted stainless barrel, whose hard-chrome rod and rolled, sealed body tolerate condensation in humid plants. A magnet comes built in as standard, so CMSG, DMSG and EMSG switches give end-of-stroke signals with no special-order piston.

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 MAC25X10SU Is Used
Z-lower on a PCB test fixture
The MAC25X10SU lowers a probe plate 10 mm onto a board under test; 245.3 N of extend force gives consistent contact pressure, and the flat U back bolts flush to the fixture plate.
Presence confirm at a pallet stop
A short kick verifies a part has arrived at the stopper; the standard magnet with a DMSG switch feeds the PLC a confirmed signal at every cycle.
Dosing-hopper slide gate
The 10 mm travel opens and closes a slide gate on a small dry-ingredient doser; the stainless rolled barrel tolerates the floury, slightly humid atmosphere above the hopper.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X10SU the Right Cylinder?
Size against the 20 mm bore at 157.0 N and the 32 mm bore at 402.2 N (0.5 MPa figures) to confirm the 25 mm is right. Connections are 1/8" ports and an M10x1.25 rod thread, rated 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi). On a centred valve the rod is unrestrained and will sag under a hanging load - fit a rod lock or pilot check valve in those cases. The flat U rear plate mates directly to machine plates; FA flange, LB foot and SDB pivot brackets, plus I and Y knuckles, round out the options.
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 MAC25X10SU FAQ
245.3 N on extension and 206.1 N on retraction at 0.5 MPa, rising to 343.4 N and 288.5 N at 0.7 MPa, with about 50 kgf theoretical at 1.0 MPa. Keep supply between 0.15-1.0 MPa (22-145 psi) and speed within 30-800 mm/s.
The high-precision stainless round barrel is rolled onto aluminium-alloy covers with a stainless block, and the carbon-steel rod carries a 20 um hard-chrome plate. That combination tolerates washdown spray, condensation and outdoor humidity far better than painted-steel minis, which rust at scratches and flake. Fluid should be air filtered to 40 um.
