Airtac MAC Stainless Steel Mini Air Cylinder MAC25X250SUFA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X250SUFA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 250mm 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 MAC25X250SUFA
Where the body itself must carry the load, the FA flange on this MAC25X250SUFA bolts the 25 mm bore flat against a machined panel, spreading thrust through the front face. Double acting with an adjustable air cushion at both ends, it makes 245.3 N of push and 206.1 N of pull at 0.5 MPa, while the stainless round barrel resists coolant splash and washdown mist far better than painted-steel minis.
Work to about 147 N of real push at 0.5 MPa and vertical lifts come out near 12 kg with a 2:1 margin. The long 250 mm travel runs on a 10 mm rod, so hold thrust in line with the bore axis and hand side loads to external guides. The piston magnet is included from the factory; adding an EMSG switch turns the cylinder into a position-sensing actuator with no special order.

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 MAC25X250SUFA Is Used
Leak-test hold-down
Clamping small pumps onto a leak-test plate on an assembly bench, the FA flange anchoring the cylinder against reaction force.
Bench bearing press
Pressing bearings into motor end bells on a manual assembly bench, 245 N of push at 0.5 MPa handling light interference fits.
Swing fixture clamp
Actuating a swing clamp on a machining-centre fixture, where the long 250 mm stroke clears part loading space.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X250SUFA the Right Cylinder?
Neighbouring bores bracket this size: 20 mm pushes 157.0 N and 32 mm pushes 402.2 N, both at 0.5 MPa, against 245.3 N here. The FA flange absorbs mounting reaction through the front face, leaving the U back cover free for rod accessories; SDB pivot or LB foot brackets work if the layout changes. Expect the rod to move the load when the valve centres and supply is cut - a pilot check valve or rod lock is the answer for held positions. Run between 30-800 mm/s and trim the cushion needles for clean stops at the faster end.
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 MAC25X250SUFA FAQ
Figures to quote: 245.3 N forward and 206.1 N back at 0.5 MPa; 343.4 N forward and 288.5 N back at 0.7 MPa; near 50 kgf theoretical at 1.0 MPa. The 10 mm rod and 1/8 inch ports pair with a 250 mm stroke that fits comfortably under the 500 mm standard limit.
The FA flange bolts the cylinder body flat to a machined face, while the U flat back cover stays free for rod accessories such as I or Y knuckles. Air enters through 1/8 inch ports threaded PT as standard, with G and NPT available on request; LB foot and SDB pivot brackets are alternatives if the layout changes.
