Airtac MAC Stainless Steel Mini Air Cylinder MAC32X120SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X120SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 120mm 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 MAC32X120SU
Cushion tuning is the headline on this model: needle screws at both ends of the 120 mm stroke let you open or close the deceleration, so faster cycles up to 800 mm/s can still land soft. The 32 mm bore produces 402 N push and 345.6 N pull at 0.5 MPa, and 563 N at 0.7 MPa.
Construction is the riveted round-body style: a stainless barrel rolled onto aluminium covers with a hard-chrome plated rod, sealing well in damp or lightly washed areas where painted minis corrode. Working effort at 0.5 MPa is about 241 N after margin - call it a 20 kg vertical lift at half rating. The U flat-end cover mounts flush, and the built-in magnet drops straight onto CMSG, DMSG or EMSG switch rails.

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 MAC32X120SU Is Used
Sortation box kicker
Deflects small parcels at a merge point; 241 N of working push moves them off the belt even when line pressure dips.
Hopper slide gate
Opens and closes a granulate gate above a dosing screw; cushions keep the gate from slamming shut at cycle end.
Light clamping on a CNC jig
Holds thin-walled parts during drilling; 402 N at 0.5 MPa grips firmly without marking soft alloys.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X120SU the Right Cylinder?
Sizing check: the 25 mm bore delivers 245.3 N at 0.5 MPa and the 40 mm bore 628.3 N - choose 32 mm only when demand falls between those numbers. Air loss or a centred valve leaves the rod unheld; the cushion exists for deceleration, so use a rod lock or pilot check for parked loads. Mount via the U cover, an FA flange or LB foot, and keep side load off the 12 mm rod across the 120 mm travel.
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 MAC32X120SU FAQ
Push is 402 N and pull 345.6 N at 0.5 MPa. At 0.7 MPa push reaches 563 N with 483.8 N pull, while the theoretical maximum is roughly 82 kgf at 1.0 MPa. The port size is 1/8 inch, the rod thread M10x1.25, and the working band 0.15-1.0 MPa (22-145 psi).
The U flat-end back cover mounts flush against a plate, and FA flange, LB foot or SDB pivot brackets can be ordered for other frames. I and Y rod knuckles suit the M10x1.25 rod. Remember that nothing locks the piston on lost air - a pilot check valve or rod lock is the answer for held positions.
