Airtac MAC Stainless Steel Mini Air Cylinder MAC25X150SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X150SCA 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 MAC25X150SCA
A 150 mm reach on a 25 mm bore makes the MAC25X150SCA a go-to for longer clearances in tight frames. Its rolled round body - stainless tube, hard-chrome 10 mm rod, riveted aluminium covers - resists corrosion in humid or lightly washed-down corners where painted minis rust. As a double-acting cylinder with variable air cushions at each end, it pushes 245.3 N and pulls 206.1 N at 0.5 MPa, and 343.4 N forward at 0.7 MPa.
Scale the numbers to real work: keep loads near 147 N and it will hoist roughly 12 kg vertically with a 2:1 margin. The CA pivot eye mounts straight onto levers and linkages, while the factory-fitted magnet accepts CMSG / DMSG / EMSG reed switches with no special-order piston. Operating window: 0.15-1.0 MPa (22-145 psi), 30-800 mm/s, -20 to +70 C.

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 MAC25X150SCA Is Used
Oven damper actuator
The stainless barrel and 150 mm stroke open steam dampers on a bakery rack oven, where humidity would eat through painted-steel cylinders in months.
Pick-and-place riser
Rated to lift about 12 kg vertically with margin, the cylinder raises a small vacuum plate carrying aluminium brackets at a robotics pick station.
Index-table detent
Pushing 245.3 N at 0.5 MPa, it seats a detent pin into a rotary indexing table, with the end cushions killing the clack on every engage.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X150SCA the Right Cylinder?
Compare the 20 mm bore (157 N push at 0.5 MPa) when headroom is tight, or move up to 32 mm for 402.2 N at the same supply. Note the rod is free-floating once air stops - centre your valve and the piston will creep, so fit a pilot check or rod lock wherever the load must stay put. The CA pivot back cover handles swinging links; FA flange, LB foot or SDB brackets cover fixed layouts. On a 150 mm stroke, external side loads will quickly wear the 10 mm rod bushings, so guide the payload separately.
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 MAC25X150SCA FAQ
Forward force at 0.5 MPa is 245.3 N with 206.1 N on retract; at 0.7 MPa those become 343.4 N and 288.5 N, topping out at a theoretical 50 kgf at 1.0 MPa. Supply 0.15-1.0 MPa (22-145 psi) of air filtered to 40 um and cycle anywhere from 30 to 800 mm/s.
Yes. The needle screws on both ends arrive set for shipping; back them off before the first run and open gradually until end-of-stroke knock disappears. This dial-in lets you push the speed toward 800 mm/s or carry heavier loads without hammering the covers.
