Airtac MAC Stainless Steel Mini Air Cylinder MAC25X150SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X150SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 150mm 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 MAC25X150SU
Flat-end U covers make this the version to bolt straight against a machine face. The MAC25X150SU is a 25 mm bore, 150 mm stroke round mini cylinder, double acting with a variable air cushion at both ends. The rolling-packed build - stainless barrel, riveted aluminium-alloy covers, chrome plated 10 mm rod - keeps washdown spray and outdoor damp from eating the body, and a magnet ships inside as standard.
Rated 245.3 N push and 206.1 N pull at 0.5 MPa, it works out to about 25 kg of thrust - derate to half, roughly 12 kg, when matching the weight of a part you need to raise. The cushions are tuned with needle screws, so end-of-stroke impact stays quiet even at 500 mm/s and beyond; open them fully on commissioning before dialling them closed.

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 MAC25X150SU Is Used
Lab tilt table
Tilts a small lab mixing tray through 150 mm of travel, the chrome rod shrugging off spills and frequent wipe-downs.
Indexing stop
Positions an indexing stop on an assembly rotary table, the U face bolted flush to the machine body.
Chute selector
Swings a chute selector flap in a recycling line, using 206.1 N of pull on the return stroke at 0.5 MPa.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X150SU the Right Cylinder?
A quick sizing check: step down to a 20 mm bore for 157.0 N at 0.5 MPa, or up to 32 mm for 402.2 N - the 25 mm at 245.3 N covers the middle band. With no air or a centred valve the piston moves freely, so fit a rod lock or pilot check valve wherever a clamped part must not shift. The U flat-end rear cover suits direct face bolting; FA flange, LB foot or SDB pivot brackets plus I / Y rod knuckles extend the mounting range. The 150 mm stroke is well inside the 500 mm standard limit for this bore, but guide the load if any side force is present.
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 MAC25X150SU FAQ
Push force is 245.3 N at 0.5 MPa and 343.4 N at 0.7 MPa; pull is 206.1 N at 0.5 MPa and 288.5 N at 0.7 MPa; theoretical peak 50.0 kgf at 1.0 MPa. The 25 mm bore breathes through 1/8 in. ports, takes 0.15-1.0 MPa (22-145 psi) working pressure, and cycles between 30-800 mm/s.
It gives a flat, fully machined rear face that bolts flush against a fixed surface, so no pivot hardware is needed at the cap. Everything else stays standard for the series - stainless barrel, air cushion both ends, and the factory magnet that pairs with CMSG, DMSG and EMSG switches.
