Airtac MAC Stainless Steel Mini Air Cylinder MAC25X350SUH
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X350SUH is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 350mm 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 MAC25X350SUH
Two letters at the end change little but the detail: the MAC25X350SUH keeps the U flat-end back cover of the plain SU, and the trailing H marks a variant suffix worth confirming on the current AirTAC datasheet before you order. The platform is unchanged - a 25 mm stainless round-body mini with riveted covers, a hard-chrome plated 10 mm rod, double acting, and needle-screw air cushions at both ends that you back off fully on first run and open gradually.
Output at 0.5 MPa is 245.3 N pushing and 206.1 N pulling, up to 343.4 N at 0.7 MPa against a 50 kgf theoretical peak. Treat 147 N as the working figure when sizing and the cylinder keeps a long service life. Vertically that is near 25 kg of lift, dropping to about 12 kg with a 2:1 margin. Every unit carries its magnet as standard, so CMSG / DMSG / EMSG switches bolt on without special orders. Supply 0.15-1.0 MPa (22-145 psi) air and cycle between 30 and 800 mm/s.

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 MAC25X350SUH Is Used
Flap tucker
Tucks closing flaps down on cartons ahead of the taping head, using the cushion for a soft, repeatable seat.
Tank lid raiser
Lifts a light mixing-tank lid of about 12 kg with a 2:1 margin against the bore's 25 kg lift capability.
Washdown gate latch
Pins a hinged gate on a wash-station conveyor where the stainless barrel resists constant water splash.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X350SUH the Right Cylinder?
This bore delivers 245.3 N of push at 0.5 MPa - comfortably more than the 20 mm MA at 157 N and clearly less than the 32 mm at 402.2 N, so both neighbours are worth checking before you settle. Fixed flat-end mounting suits plates and brackets; FA flange, LB foot or SDB hardware extends the options. Since the piston floats whenever air pressure disappears, add a rod lock or pilot check valve for any position that must be kept. With a 350 mm stroke, avoid side thrust by guiding the load in its own bearings. Ports are 1/8-inch and the rod thread is M10x1.25.
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 MAC25X350SUH FAQ
Push 245.3 N and pull 206.1 N at 0.5 MPa; push 343.4 N and pull 288.5 N at 0.7 MPa; theoretical maximum 50 kgf at 1.0 MPa. It is double acting with a variable cushion at both ends, accepts 0.15-1.0 MPa (22-145 psi), and strokes from 30 to 800 mm/s.
Nothing extra - the magnet is built into the piston as standard on the MA series, so CMSG, DMSG and EMSG switches simply clip onto the stainless barrel to signal extend and retract positions. No special-order piston is ever required.
