Airtac MAC Stainless Steel Mini Air Cylinder MAC25X95SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X95SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 95mm 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 MAC25X95SU
Fixed-face mounting is the point of the U flat-end cover here: bolt the flat back straight to a machine plate and let the 95 mm stroke work. The 25 mm bore reads 245 N push and 206 N pull at 0.5 MPa, climbing to 343 N at 0.7 MPa, with a variable cushion bleeding off impact at each end so heavier loads arrive quietly.
Because the piston drifts the moment air drops, add a rod lock or pilot check valve if the load must stay parked - the cushion softens, it never holds. Expect about 147 N of dependable push at 0.5 MPa and about 12 kg of vertical lift with a 2:1 margin, and the standard magnet pairs with CMSG or EMSG switches.

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 MAC25X95SU Is Used
Vial tray press-down
Settles vial trays into nests on a pharma packing line; cushioned ends stop glass rattling and the stainless body wipes clean with IPA.
Valve test bench actuator
Strokes small ball valves through open-close cycles on a test rig; 343 N at 0.7 MPa turns handles against seat torque.
Tile spacer ejector
Kicks spacer inserts from a mould in a ceramics workshop; the flat U cover mounts flush to the mould plate for a compact build.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X95SU the Right Cylinder?
Force ladder at 0.5 MPa: 157 N on the 20 mm bore, 245 N here at 25 mm, 402 N on the 32 mm - pick by the load, not the price. The U flat-end back cover mounts directly; SDB pivot brackets and I or Y knuckles handle swinging joints, and the standard magnet drops a CMSG or EMSG switch straight on. With 95 mm of stroke keep the load aligned to the rod axis, since side loading bends the slim 10 mm piston rod. Air loss lets the piston coast, so specify a check valve for parked loads.
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 MAC25X95SU FAQ
At 0.5 MPa: 245 N push, 206 N pull. At 0.7 MPa: 343 N push, 289 N pull. The 1.0 MPa theoretical maximum is 50 kgf. Working pressure spans 0.15-1.0 MPa (22-145 psi) and speed 30-800 mm/s.
No - as a double-acting cylinder with no internal lock, the piston drifts when supply is lost or the valve centres. Add a rod lock or pilot check valve where a parked load must stay put; the cushion only softens impact, it never locks.
