Airtac MAC Stainless Steel Mini Air Cylinder MAC32X115SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X115SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 115mm 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 MAC32X115SU
With a 32 mm bore, this MAC puts out 402 N of push and 345.6 N of pull at 0.5 MPa, rising to 563 N at 0.7 MPa - roughly an 82 kgf theoretical ceiling at 1.0 MPa. Air drives the rod in both directions and a variable cushion at each end bleeds off impact, so the 115 mm stroke can run toward the top of the 30-800 mm/s band without hammering the covers.
The body is a rolled stainless barrel with a hard-chrome plated rod, so washdown mist and outdoor damp do not chew it up the way painted mini cylinders fade. The U flat-end back cover bolts flush to a plate with no pivot hardware, and the built-in magnet accepts CMSG, DMSG or EMSG switches as standard. Plan on about 241 N of real working force at 0.5 MPa - enough to lift roughly 20 kg vertically with a 2:1 margin.

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 MAC32X115SU Is Used
Carton kick-off at a checkweigher
Pushes a filled 15 kg shipper off the belt into the reject lane; 241 N of practical force at 0.5 MPa clears the job with room to spare.
Dowel-pin staking fixture
A short press action seats pins into aluminium housings; the 402 N bore rating and cushioned landings protect fragile parts.
Bottle lane diverter
Sweeps containers off a filling line at up to 800 mm/s; the flat U back cover bolts straight to the guarding channel.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X115SU the Right Cylinder?
Compare before you buy: a 25 mm bore pushes 245.3 N at 0.5 MPa and a 40 mm bore reaches 628.3 N, so 32 mm sits between them for mid-weight work. The cushion decelerates the rod but never arrests it - when the valve centres, the load drifts, so add a pilot check valve or rod lock where position must persist. The flat U cover suits plate mounting, and the standard magnet means switch sensing needs no special order.
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 MAC32X115SU FAQ
At 0.5 MPa it pushes 402 N and pulls 345.6 N. At 0.7 MPa the figures rise to 563 N push and 483.8 N pull, and the theoretical ceiling is about 82 kgf at 1.0 MPa. Operating pressure runs 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof, the port is 1/8 inch and the rod thread M10x1.25.
The barrel is stainless steel, the carbon-steel rod is hard-chrome plated to 20 um, and the aluminium covers are rolled onto the tube rather than tied. That combination tolerates washdown mist and outdoor humidity far better than painted mini cylinders, and the 12 mm rod resists bending under light side loads.
