Airtac MAC Stainless Steel Mini Air Cylinder MAC32X40SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X40SCM 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 MAC32X40SCM
Built around a rolled stainless tube with riveted aluminium covers, the MAC32X40SCM forms a sealed round body that survives rinse-down in wet or dusty plants. Air powers the piston both ways, and the variable cushion at each end is tuned with its own needle screw, so line speed can climb toward 800 mm/s without the covers taking a beating.
Push force at 0.5 MPa is 402 N with 346 N on the return stroke; 0.7 MPa lifts push to 563 N. That is enough to raise roughly 41 kg vertically in theory - halve it for a 2:1 margin and you can lift about 20 kg of real part weight per stroke. The CM round-end back cover suits pin-type fixed mountings, and the factory-fitted magnet lets an EMSG or CMSG switch drop on with no special 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 MAC32X40SCM Is Used
Carton reject pusher
Kicks rejected cartons off a secondary packaging line, cushioned both ends so fast belts do not jar the mechanism.
Bottle rinser actuator
Raises and lowers rinse nozzles over a brewery bottling station, where the stainless tube handles constant splashing.
Slide gate on tote conveyor
Slides divert gates across a warehouse tote line; DMSG switches confirm gate position before totes are released.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X40SCM the Right Cylinder?
Compare before you buy: the 25 mm bore gives 245 N push at 0.5 MPa and the next size up, 40 mm, reaches 628 N - at 402 N the 32 mm is the sweet spot for medium clamps and ejectors. If the load must stay put with the valve centred, remember air pressure rather than the cushion does the holding, so spec a rod lock or pilot check valve. Foot (LB), flange (FA) and pivot (SDB) brackets plus I and Y knuckles cover the rest of the machine layout.
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 MAC32X40SCM FAQ
Figures for the 32 mm bore: push 402 N and pull 346 N at 0.5 MPa; push 563 N and pull 484 N at 0.7 MPa; theoretical peak 82 kgf at 1.0 MPa. Pressure window is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof, and air enters via 1/8" ports.
Both ends carry a variable air cushion with its own needle screw. Start with the screws backed off, run the cylinder slowly, then close them a turn at a time until end-of-stroke impact disappears - never screw them fully shut, or the piston will bottom hard against the cover.
