Airtac MAC Stainless Steel Mini Air Cylinder MAC32X55SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X55SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 55mm 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 MAC32X55SU
A flat-end U back cover and a 55 mm stroke make the MAC32X55SU easy to bolt flat against a machine plate, while the 32 mm bore swings 402 N of push at 0.5 MPa. Double acting with a variable air cushion at both ends, it accepts 0.15-1.0 MPa (22-145 psi) and cycles anywhere from 30 to 800 mm/s.
Grease-storing two-way piston seals keep lubrication inside the barrel between services, and the riveted stainless round body shrugs off splashes that rust painted minis. Vertically, the 402 N push equates to lifting about 41 kg - halve that to roughly 20 kg if you want a 2:1 margin against a real part weight. Every unit ships with the magnet already fitted, so CMSG, DMSG or EMSG reed switches clip on for position feedback without a special-order piston.

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 MAC32X55SU Is Used
Fixture clamp on a welding jig
Clamping steel brackets into a welding jig with 241 N of working force, holding the parts square while the robot lays the bead.
Cap press on a filling line
Pressing caps home on 300 ml shampoo bottles; the 55 mm stroke matches the cap depth and the cushion kills the impact at full seat.
Slide stopper on a linear rail
Stopping and seating tooling plates on a linear slide index, with the flat-end U cover bolted direct to the machine plate.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X55SU the Right Cylinder?
Compare bores by 0.5 MPa push: 25 mm gives 245 N, this 32 mm bore 402 N, and the 40 mm bore 628 N - all on the same 1/8" port. The U flat-end cover suits fixed, flush mounting; choose the CA pivot version instead if the rod must swing. If the load must stay clamped through a power loss, note the MAC piston drifts freely when air drops - a rod lock or pilot check valve is the fix, 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 MAC32X55SU FAQ
Push at 0.5 MPa is 402 N, pull 345.6 N; at 0.7 MPa expect 563 N push and 483.8 N pull, with a theoretical maximum of 82 kgf at 1.0 MPa. Air supply 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed range 30-800 mm/s, and the air must be filtered to 40 um.
The U flat-end back cover bolts flush against a bracket or machine plate, so no pivot pin is needed for fixed mounting. Add an FA flange, LB foot or SDB pivot bracket if the layout demands it, and an I or Y rod knuckle where the load could introduce side-play into the 12 mm rod.
