Airtac MAC Stainless Steel Mini Air Cylinder MAC32X25SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X25SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 25mm 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 MAC32X25SU
With a flat U end cover that bolts flush against a fixed plate, the MAC32X25SU turns 402 N of push at 0.5 MPa into a clean inline thrust unit for gating and light press work. Its stainless round barrel is riveted between aluminium-alloy covers, so the sealed body shrugs off splash and humidity that would rust a painted mini.
It is double acting with a variable cushion at each end, and speed can be tuned anywhere from 30 to 800 mm/s. For sizing, treat about 241 N - 60% of the 0.5 MPa push figure - as realistic working force, and expect up to 82 kgf at the 1.0 MPa theoretical limit. The magnet is built in as standard for CMSG, DMSG and EMSG switches.

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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 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 MAC32X25SU Is Used
Reject pusher
Pushing defective blister packs off a pharmaceutical checkweigher belt into a bin; 402 N at 0.5 MPa clears the pack within the 25 mm sweep.
Guard interlock ram
Sliding a machine guard latch on a sheet-metal press brake, with the flat U cover bolted directly to the guard channel.
Carton flap tuck
Tucking the final flap on a small carton closer at the end of a bakery line, with the cushion tuned so the flap seats without denting the board.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X25SU the Right Cylinder?
Size it against neighbours: the 25 mm bore pushes 245 N at 0.5 MPa and the 40 mm bore 628 N, placing this 32 mm unit at 402 N for medium-duty thrust. A flat U back cover plus an FA flange or LB foot gives a fully fixed installation, while CA pivot or CM covers suit swinging loads if the mount changes later. Air ports are 1/8" on every 32 mm bore with PT, G or NPT thread options. If the machine must hold position through a power loss, remember a plain double-acting cylinder relaxes - fit a rod lock or pilot check valve.
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 MAC32X25SU FAQ
The 32 mm bore pushes 402 N and pulls 346 N at 0.5 MPa; at 0.7 MPa the figures are 563 N push and 484 N pull, with a theoretical maximum of 82 kgf at 1.0 MPa. Rated pressure is 0.15-1.0 MPa (22-145 psi) and proof pressure is 1.5 MPa (215 psi).
The built-in magnet is standard, so CMSG, DMSG and EMSG switches clamp onto the barrel without ordering a magnetised piston. Mounting options include the FA flange, LB foot and SDB pivot bracket, plus I or Y rod knuckles; the U flat-end cover on this version bolts directly to a flat machine face.
