Airtac MAC Stainless Steel Mini Air Cylinder MAC25X15SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X15SCM 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 MAC25X15SCM
With a round-end CM back cover, this 15 mm stroke MAC drops onto a head pin or lug with no bracket to machine - pin it, air it, run it. The 25 mm bore pushes 245.3 N at 0.5 MPa and pulls 206.1 N, ample for short-jaw clamps, kickers and positioners working in a 15 mm window; roughly 147 N of that push is sensible usable force at 0.5 MPa.
Inside, a stainless-steel barrel is roll-packed onto aluminium covers with a hard-chrome plated rod, a pairing that survives coolant splash and dusty yards far better than painted mini cylinders. Air drives both directions, the variable cushion at each end soaks up the stop, and the standard piston magnet feeds position signals to CMSG, DMSG or EMSG switches. Pressure spans 0.15-1.0 MPa (22-145 psi).

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 MAC25X15SCM Is Used
Pin-hung gripper jaw
Hangs from a head pin at a pick station and closes a jaw in 15 mm, giving 245.3 N of grip at 0.5 MPa on small housings.
Carton stopper blade
Pops a stop blade up into carton flow on a case packer, cushioned both ways so the blade never rattles the guide rails.
Lab autosampler tray latch
Pins sample tray positions in 15 mm increments, with an EMSG switch on the standard magnet confirming each latch to the controller.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X15SCM the Right Cylinder?
Drop to a 16 mm bore (100.5 N push at 0.5 MPa) for tiny grippers, or move to 32 mm (402.2 N) for stiff clamping. Port size on this bore is 1/8" and the rod carries an M10x1.25 thread. A pinned CM end is meant for pivoting duty, so let the pin swing with the load and keep side force on the 15 mm stroke close to zero. When air fails the rod simply moves - fit a pilot check valve or rod lock if a position must be held.
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 MAC25X15SCM FAQ
Rated output at 0.5 MPa is 245.3 N push and 206.1 N pull. At 0.7 MPa expect 343.4 N push and 288.5 N pull, with roughly 50 kgf as the theoretical maximum at 1.0 MPa. It is double acting with a variable air cushion at both ends of the stroke.
No. Every MAC ships with the piston magnet already installed, so CMSG, DMSG or EMSG switches clip onto the stainless barrel and detect position out of the box - no special piston, no factory option to order.
