Airtac MAC Stainless Steel Mini Air Cylinder MAC25X15SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X15SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 15mm 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 MAC25X15SCA
Fifteen millimetres of stroke is often all a clamp jaw or ejector needs, and this 25 mm MAC delivers 245.3 N of push at 0.5 MPa (206.1 N on retract) inside a very short body. Treat about 147 N as the practical working force at 0.5 MPa and it will cycle for years. The stainless barrel is rolled onto aluminium covers, so chips, coolant mist and washdown do not eat it the way they attack painted minis.
The CA pivot back cover accepts a clevis pin, making the unit a natural swing clamp where the jaw rotates through a small arc. A variable cushion at both ends still comes standard - handy when a jaw snaps onto a hard stop - and the built-in magnet works with CMSG, DMSG and EMSG switches without ordering a special piston. Double acting, 0.15-1.0 MPa (22-145 psi), 30-800 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 MAC25X15SCA Is Used
Small-arc swing clamp
A machining-fixture clamp that pivots through 15 mm and squeezes with 245.3 N at 0.5 MPa, pinned directly to the CA eye with no bracket.
Chute part kicker
Flicks off-cuts sideways off a gravity chute every few seconds; the short stroke keeps cycle time fast at 800 mm/s.
Inspection rig latch
Locks a hinged lid on a test station, with the standard magnet feeding a DMSG switch so the PLC knows the latch is closed before the test starts.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X15SCA the Right Cylinder?
Compare a 16 mm bore at 100.5 N push if the clamp is light, or a 32 mm bore at 402.2 N for heavy fixture work. This bore uses 1/8" ports and an M10x1.25 rod thread. If the valve centres while the part is clamped, the jaw will relax - a MAC holds nothing without air - so a pilot check valve keeps clamp force through signal loss. FA flange, LB foot or SDB pivot brackets adapt the short body to nearly any fixture plate.
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 MAC25X15SCA FAQ
At 0.5 MPa: 245.3 N push and 206.1 N pull. At 0.7 MPa: 343.4 N push and 288.5 N pull. Theoretical maximum about 50 kgf at 1.0 MPa. Air powers both directions and a variable cushion sits at each end of the 15 mm stroke.
Yes, better than most minis: the round barrel is stainless steel riveted to aluminium covers and the rod is hard-chrome plated, so mild corrosion, splash and outdoor dust are not a problem. Keep supply air filtered to 40 um and within -20 to +70 C.
