Airtac MAC Stainless Steel Mini Air Cylinder MAC32X730SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X730SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 730mm 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 MAC32X730SU
At 730 mm of travel, the MAC32X730SU stretches AirTAC's 32 mm round-body mini family well past its 500 mm standard limit, so the stroke is manufactured to order. It is double acting, with a variable air cushion at each end, and pushes 402.2 N at 0.5 MPa (pull 345.6 N). Keep real work near 241 N - that is about 60 percent of the rating, or roughly 20 kg lifted vertically with a 2:1 margin.
The stainless barrel and hard-chrome plated 12 mm rod shrug off washdown and humid air that would rust a painted mini, while the riveted aluminium covers keep the joint sealed. A magnet comes built in, so CMSG, DMSG or EMSG switches drop on without ordering a special piston. The flat-end U back cover bolts straight to a fixed plate with no adapter, and the cushion needles let you tune out end-of-stroke shock as speeds approach the 800 mm/s ceiling. On a stroke this long, guide the load externally so side thrust never bends the rod.

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 MAC32X730SU Is Used
Carton diverting gate
The 730 mm stroke sweeps a deflector across a wide sorter lane, pushing cartons to a reject spur with 402 N of push at 0.5 MPa.
Wide fixture clamping
Clamps broad automotive trim panels in a check fixture, where the long reach spans the part and the U flat-end cover bolts to the frame.
Deep-chute part ejection
Clears jammed housings from the bottom of a gravity feed chute on an electronics line, with cushioned seating at both ends.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X730SU the Right Cylinder?
Cross-check the bore before committing: 25 mm offers 245.3 N at 0.5 MPa, this 32 mm unit 402.2 N, and 40 mm lifts the figure to 628.3 N. Working pressure spans 0.15-1.0 MPa (22-145 psi) and speed runs 30-800 mm/s. The rod is free to drift whenever air is removed or the valve centres - the air cushion damps impact but never locks position - so fit a rod lock or pilot check valve where a held load matters. LB foot and FA flange brackets adapt the U flat-end cover to fixed frames, and the built-in magnet keeps sensing possible across all 730 mm.
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 MAC32X730SU FAQ
At 0.5 MPa it pushes 402.2 N and pulls 345.6 N; at 0.7 MPa the numbers are 563.0 N and 483.8 N, with a theoretical 82 kgf at 1.0 MPa. The 12 mm rod carries an M10x1.25 male thread, air ports are 1/8", and supply may run 0.15-1.0 MPa (22-145 psi).
Back both cushion needle screws fully off before first air, then close them a turn at a time until the end-of-stroke knock fades. The cushion is variable, not fixed, so retune whenever speed or load changes. Keep travel within 30-800 mm/s and supply within 0.15-1.0 MPa (22-145 psi), and never rely on the cushion to hold a load - it only absorbs impact.
