Airtac MAC Stainless Steel Mini Air Cylinder MAC32X70SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X70SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 70mm 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 MAC32X70SU
Flat-ended, flush-mounted, quietly strong: the MAC32X70SU offers 402 N of push at 0.5 MPa from a 32 mm bore, with 346 N of pull the other way. It is a double-acting AirTAC MAC mini cylinder, and the variable air cushion at both ends keeps even the 800 mm/s top speed from hammering the aluminium covers.
Its U back cover presents a flat machined face for direct bolting, riveted to the stainless barrel in the same rolling-packed joint that shrugs off washdown and mild corrosion. The magnet is built in as standard equipment, so CMSG / DMSG / EMSG switches mount without ordering a special piston. Practical planning figure: about 240 N of push at 0.5 MPa, close to a 20 kg vertical lift 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 MAC32X70SU Is Used
Pallet-stopper pop-up
Raising a stop blade at the end of a pallet conveyor spur, bolted flat through the U cover.
Cabinet-door test rig
Cycling kitchen cabinet hinges on a durability bench, cushioned so the 70 mm throw stays quiet overnight.
Label-head hold-down
Pressing a labeling head lightly onto bottles on a bottling line, where washdown tolerance matters.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X70SU the Right Cylinder?
Pick the U cover when the cylinder face butts against a fixed plate; add FA flange or LB foot hardware if you want bolt-through security, or SDB for a pivoting link. Against neighbouring bores: a 25 mm MAC gives 245 N at 0.5 MPa and a 40 mm gives 628 N, so this 32 mm sits mid-pack at 402 N. The 70 mm stroke is standard, well under the 500 mm bore-32 limit; run 0.15-1.0 MPa (22-145 psi) and 30-800 mm/s. If the load must stay put on air loss, remember the rod drifts - a rod lock or pilot check valve is the answer, not the cushion.
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 MAC32X70SU FAQ
At 0.5 MPa: 402 N push, 346 N pull. At 0.7 MPa: 563 N push, 484 N pull. Theoretical maximum 82 kgf. Bore 32 mm, 70 mm stroke, port 1/8", supply 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s.
It gives a flat end face that bolts directly against machine plates without an intermediate bracket, and like the CA pivot and CM round-end options it is riveted onto the stainless barrel at the factory. Add FA, LB or SDB mounts when the frame needs them.
