Airtac MAC Stainless Steel Mini Air Cylinder MAC32X90SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X90SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 90mm 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 MAC32X90SU
Where a painted mini cylinder would flake and rust, this one keeps a stainless barrel and a 20 um hard-chrome rod - a practical pick for damp corners, food benches and outdoor gates. The 90 mm stroke extends a 12 mm rod, double acting, with a variable air cushion at each end to dial out impact.
At 0.5 MPa the bore produces 402.2 N on extend and 345.6 N on retract; budget about 241 N for the actual job and the mechanism will not run out of steam. Since the magnet is standard, CMSG, DMSG or EMSG switches give end-position signals straight from the box.

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 MAC32X90SU Is Used
Greenhouse vent openers
Opening roof vents on greenhouse frames where constant humidity would destroy painted cylinders.
Tray pushers in bakeries
Pushing dough trays onto an oven loader; the stainless body wipes down between shifts.
Small vertical lifts
Raising a 15 kg jig platform vertically on a dial-indexing bench, well inside the bore's lift capacity.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X90SU the Right Cylinder?
If 402.2 N at 0.5 MPa is more than the task needs, the 25 mm bore (245.3 N) saves air and money; if the load grows, step to the 40 mm bore with 628.3 N. The rod is free to move when air is cut - for a position that must hold, fit a rod lock or pilot check valve rather than relying on the cushion. The U flat-end cover bolts directly to brackets; FA flange, LB foot or SDB pivot options suit different frames. With 90 mm of travel, guide the load so side forces never reach the rod.
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 MAC32X90SU FAQ
Force at 0.5 MPa is 402.2 N pushing and 345.6 N pulling; at 0.7 MPa it reaches 563.0 N and 483.8 N respectively, peaking at a theoretical 82.0 kgf at 1.0 MPa. The cylinder accepts 0.15-1.0 MPa (22-145 psi) and moves at 30-800 mm/s across its 90 mm stroke.
No - being double acting with no spring or lock, the rod drifts once pressure is gone, and the air cushion only softens arrival, it never brakes the piston. Where a load must stay put, add a rod lock cylinder or a pilot check valve in the line.
