Airtac MAC Stainless Steel Mini Air Cylinder MAC32X80SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X80SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 80mm 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 MAC32X80SU
A double acting round-body mini cylinder with a 32 mm bore and an 80 mm stroke, the MAC32X80SU is finished with the U flat-end back cover for a clean fixed mounting face. At 0.5 MPa it pushes 402 N and pulls 346 N; at 0.7 MPa those figures rise to 563 N and 484 N, with a theoretical 82 kgf peak. The barrel is stainless steel rolled onto aluminium covers, and the hard-chrome plated carbon-steel rod shrugs off mild corrosion and washdown where painted-steel minis would flake.
A variable air cushion at both ends lets you bleed off end-of-stroke shock, so a fast 80 mm cycle runs without hammering the covers. The magnet comes built in as standard, so CMSG, DMSG or EMSG switches clip on with no special-order piston. In day-to-day sizing, count on roughly 241 N of usable push at 0.5 MPa, and the bore will lift about 20 kg vertically once a 2:1 margin is kept. Speed spans 30-800 mm/s over 0.15-1.0 MPa (22-145 psi).

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 MAC32X80SU Is Used
Bench die ejector
At 402 N of push, the 32 mm bore knocks cooled brass terminals out of a 60 mm punch die on a manual press bench, with the cushion easing the return stroke.
Checkweigher reject kicker
Mounted beside a checkweigher, the flat-end body sidesteps underweight cartons off the belt at up to 800 mm/s without jolting the lane.
Extrusion weld fixture clamp
The 241 N working force holds square aluminium profile joints square while the TIG pass runs along the seam.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X80SU the Right Cylinder?
Size down to the 25 mm bore (245 N push at 0.5 MPa) when 402 N is more than the job needs, or up to the 40 mm bore for 628 N on the same supply. Keep in mind the MAC cannot park a load: when air is removed or the valve centres, the piston drifts freely, so a rod lock or pilot check valve is the answer wherever position matters. The U flat-end cover mounts straight onto fixed plates, FA flange and LB foot brackets bolt on, and the built-in magnet keeps CMSG / DMSG / EMSG sensing open to you. Over its 80 mm stroke, keep side thrust off the 12 mm rod with external guides.
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 MAC32X80SU FAQ
At 0.5 MPa the 32 mm bore pushes 402 N and pulls 346 N; at 0.7 MPa it reaches 563 N push and 484 N pull, with 82 kgf as the theoretical maximum at 1.0 MPa. Ports are 1/8", the 12 mm rod carries an M10x1.25 male thread, stroke is 80 mm inside the 500 mm standard limit, and working pressure spans 0.15-1.0 MPa (22-145 psi).
The U flat-end back cover presents a fixed face for direct bolting, with FA flange, LB foot and SDB pivot brackets available if the frame needs them. Both ends carry a variable air cushion: back the needle screws off for first run-up, then close them gradually until end-of-stroke shock disappears.
