Airtac MAC Stainless Steel Mini Air Cylinder MAC25X180SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X180SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 180mm 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 MAC25X180SU
Rust stops at the barrel of the MAC25X180SU: the stainless round tube, riveted aluminium covers and 20 um hard-chrome plated 10 mm rod take damp, splash and outdoor duty that wrecks painted minis. Double acting with variable air cushion at both ends, it pushes 245.3 N at 0.5 MPa - plan around 147 N of that as usable work.
Position feedback needs no options: the magnet is standard, so CMSG, DMSG and EMSG switches clip straight on. Cushion needles at both ends let you tune the 180 mm stroke from gentle to firm, and the U flat-end covers bolt the body directly to a machine plate. Working envelope: 0.15-1.0 MPa (22-145 psi), 30-800 mm/s, air filtered to 40 um.

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 MAC25X180SU Is Used
Ejecting finished parts from a mold tray
245 N at 0.5 MPa sweeps injection-molded caps off the tray in a 180 mm stroke while the cushion stops parts skidding at the far end.
Bottle gate on a rinsing line
Stainless barrel and chrome rod shrug off constant water splash as the gate opens and closes to release bottles past the rinser.
Position-checked stopper on an assembly conveyor
A DMSG switch on the standard magnet confirms the stopper is fully extended before the robot places the next part.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X180SU the Right Cylinder?
Between the 157 N bore 20 and the 402 N bore 32, this 25 mm bore lands in the middle at 245.3 N push and 206.1 N pull at 0.5 MPa - pick smaller to save air, larger when the payload climbs. Air-off holding is zero: the rod drifts when the valve centres, so a pilot check valve or rod lock protects parked loads. For 180 mm travels keep the 10 mm rod straight - external guides absorb side loads that would bend it. Mount with the flat U cover, or add FA flange, LB foot or SDB pivot hardware; PT, G and NPT threads all order on the 1/8" ports.
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 MAC25X180SU FAQ
At 0.5 MPa the MAC25X180SU pushes 245.3 N and pulls 206.1 N; at 0.7 MPa, 343.4 N push and 288.5 N pull; theoretical maximum 50 kgf at 1.0 MPa. Speed range is 30-800 mm/s and pressure runs 0.15-1.0 MPa (22-145 psi).
Back both cushion needle screws fully off before start-up, then close them gradually until end-of-stroke impact fades. The cushion is variable, not fixed, so it adapts to the load and speed rather than fighting them. Do not mistake it for a brake - the cylinder cannot hold a load when air is lost.
