Airtac MAC Stainless Steel Mini Air Cylinder MAC32X40SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X40SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 40mm 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 MAC32X40SU
Flat-end U back cover, 32 mm bore, 40 mm stroke - the MAC32X40SU keeps a slim profile where panels or guards sit close to the cylinder body. A 20 um hard-chrome layer over the steel rod plus the stainless barrel resists rust in humid plants and mild outdoor exposure. Air drives the piston in both directions, and each end carries a cushion adjustable with its needle screw.
Figures to size against: 402 N push and 346 N pull at 0.5 MPa, climbing to 563 N and 484 N at 0.7 MPa. Theoretical vertical lift works out near 41 kg; keeping a 2:1 margin leaves about 20 kg of real payload per lift. Speed control spans 30-800 mm/s, and the magnet ships installed, so a DMSG switch gives end-of-stroke signals from the first cycle.

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 MAC32X40SU Is Used
Guard door interlock
Opens and closes a CNC machine guard door, its flat U cover mounting flush against the enclosure panel.
PCB test fixture clamp
Presses probe boards onto PCBAs in an ICT test rig, with EMSG switches confirming the clamped state.
Small heat-press ejector
Ejects finished badges from a compact heat press at up to 800 mm/s without end-of-stroke bang thanks to the air cushion.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X40SU the Right Cylinder?
For this force band the 32 mm MAC sits between the 25 mm bore (245 N push at 0.5 MPa) and the 40 mm (628 N) - choose the smaller bore when air economy and cycle speed dominate, the 40 mm when loads approach 350 N. The piston will not lock itself: centre the valve under a hanging load and it creeps, so a rod lock is the answer where that matters. The U flat end bolts flush to plates, while FA flange, LB foot or SDB pivot brackets adapt it to frames.
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 MAC32X40SU FAQ
Push 402 N and pull 346 N at 0.5 MPa; push 563 N and pull 484 N at 0.7 MPa; theoretical maximum 82 kgf at 1.0 MPa. It runs on 0.15-1.0 MPa (22-145 psi), survives 1.5 MPa (215 psi) proof, cycles 30-800 mm/s and connects through 1/8" ports.
The stainless tube with a hard-chrome plated 12 mm rod resists corrosion from washdown, humidity and outdoor drip, so it lasts where painted bodies chip and rust. The riveted covers keep the body sealed, and the built-in magnet stays ready for CMSG or DMSG switches.
