Airtac MAC Stainless Steel Mini Air Cylinder MAC25X15SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X15SU 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 MAC25X15SU
Short-stroke clamping is exactly where this model earns its keep: a 15 mm throw on AirTAC's 25 mm round-body MAC, double acting so air drives the rod out and back, with a variable cushion at each end to soften the last millimetres. At 0.5 MPa it pushes 245.3 N and pulls 206.1 N - firm grip for a fixture clamp on ordinary shop air.
The stainless round barrel plus a 20 um hard-chrome rod shrug off coolant mist that blisters painted minis, and the riveted aluminium covers seal the tube without tie rods. Work to roughly 147 N of usable push at 0.5 MPa rather than the full rating - about 12 kg of vertical lift once you keep a margin - and the magnet that ships built in lets a CMSG switch flag end positions from day one.

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 MAC25X15SU Is Used
Fixture clamping
Clamp small aluminium brackets against a CNC jig - 245 N of push at 0.5 MPa holds thin parts firmly without crushing them.
Pin ejection
Eject finished connectors or dowel pins from a small die; the 15 mm throw matches shallow part pockets exactly.
Vial gating
Kick single vials aside on a pharma filling line; the stainless barrel stands up to frequent wipe-downs.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X15SU the Right Cylinder?
Keep the bore honest at this stroke: a 20 mm MAC manages only 157 N at 0.5 MPa, while a 32 mm bore buys 402.2 N if your clamp needs more bite. The U flat-end cover bolts straight against a fixed face; an LB foot, FA flange or SDB pivot bracket covers frame mounting. Air off, the rod moves freely, so a pilot check valve is the answer when a clamp has to stay shut. Supply 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s.
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 MAC25X15SU FAQ
At 0.5 MPa it pushes 245.3 N and pulls 206.1 N; at 0.7 MPa the figures are 343.4 N push and 288.5 N pull. Theoretical peak is 50 kgf at 1.0 MPa. Bore 25 mm, rod 10 mm, 1/8 in ports, M10x1.25 male rod thread. Operating range 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-800 mm/s.
Both ends carry a variable air cushion. Back the needle screws fully off before the first cycle, then close them gradually until end-of-stroke shock disappears at your working speed.
