Airtac MAC Stainless Steel Mini Air Cylinder MAC25X110SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X110SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 110mm 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 MAC25X110SU
Double acting by design, the MAC25X110SU pushes with 245.3 N and retracts with 206.1 N at 0.5 MPa; at 0.7 MPa push climbs to 343.4 N, close to the 50 kgf theoretical ceiling of this bore. The U flat-end back cover gives a clean fixed mount that bolts straight to a machine face.
Both ends carry a variable air cushion: back the needle screws off on first run-up, then open them gradually to soften stops at speeds up to 800 mm/s. The stainless round body tolerates damp, rinse-prone areas that pit painted minis. Plan tooling around about 147 N of usable push at 0.5 MPa and the cylinder keeps a comfortable reserve.

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 MAC25X110SU Is Used
Clamp fixture
The flat-end U cover seats against a drill-press jig, holding workpieces with 245.3 N of clamping push at 0.5 MPa.
Lane diverter
Pushes a diverter plate across a bottling line lane at up to 800 mm/s; cushions soften the plate at both stops.
Washdown ejector
The stainless barrel survives rinse-prone food benches as the rod kicks offcut scrap into a bin each cycle.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X110SU the Right Cylinder?
Downsize to a 20 mm bore (157.0 N push at 0.5 MPa) for light clamping or upsize to 32 mm (402.2 N) for heavier presses - the 25 mm bore's 245.3 N sits between. When the supply drops or the valve returns to centre, the rod moves freely, so a rod lock or pilot check valve is needed for held loads. The U flat-end back cover plus an FA flange or LB foot covers fixed installations, and I or Y rod knuckles handle off-axis links. Side-load the 110 mm stroke sparingly and guide the tooling 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 MAC25X110SU FAQ
Push is 245.3 N and pull 206.1 N at 0.5 MPa; at 0.7 MPa push rises to 343.4 N and pull to 288.5 N. Theoretical maximum force at 1.0 MPa is about 50 kgf. The 10 mm rod carries an M10x1.25 thread and the air ports are 1/8".
The round barrel is stainless steel and the carbon-steel rod is hard-chrome plated to about 20 um, so the pair resists washdown and mild corrosion far better than painted minis. Covers are aluminium alloy, riveted and rolled onto the tube for a sealed body; operating range is -20 to +70 C at 0.15-1.0 MPa (22-145 psi).
