Airtac MAC Stainless Steel Mini Air Cylinder MAC32X240SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X240SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 240mm 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 MAC32X240SCA
At 240 mm of stroke, the MAC32X240SCA reaches across wide fixtures while keeping the 32 mm bore's 402 N push force at 0.5 MPa. AirTAC rivets the stainless barrel between aluminium covers, and a variable air cushion at each end tames the shock of long travel.
Back the cushion needle screws off fully on first run and close them gradually as speed rises toward 800 mm/s. The piston magnet is fitted as standard, so a CMSG or DMSG switch signals both stroke ends without modification. Derated to 60% of the push rating, you get about 241 N of honest working force for load calculations.

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 MAC32X240SCA Is Used
Case ejector on a cartoner
Pushing finished cartons off an infeed chain across a 240 mm gap, the cushions absorbing the stop even at 800 mm/s cycle speeds.
Lift stage between assembly nests
Raising part nests 240 mm between stations, with about 20 kg of vertical lift capability at a 2:1 margin from the 402 N push rating.
Interlocked fence gate actuator
Driving a robot-cell gate open and closed, CMSG switches on both stroke ends feeding PLC interlock signals.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X240SCA the Right Cylinder?
The 240 mm stroke sits well inside the 500 mm standard range for bore 32, so it is a catalog part, not a special. Smaller MAC25 units manage 245 N push at 0.5 MPa; the next bore up, MAC40, delivers 628 N. Keep lateral load off the rod with external guides - side thrust stresses a 12 mm rod long before the force rating is approached. Position holding is not built in; when air fails the rod drifts, so specify a rod lock or pilot check valve. The CA pivot cover plus an SDB bracket covers swinging lever mechanisms.
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 MAC32X240SCA FAQ
At 0.5 MPa: 402.2 N push and 345.6 N pull. At 0.7 MPa: 563.0 N push and 483.8 N pull. Theoretical maximum at 1.0 MPa is 82 kgf. It is double acting with variable air cushions at both ends, operating on 0.15-1.0 MPa (22-145 psi) air at 30-800 mm/s through 1/8" ports.
Back both needle screws fully off, run the cylinder, then close them gradually until end-of-stroke bounce disappears. The variable cushion lets you trade braking firmness against cycle speed, so faster runs or heavier loads up to the 402.2 N push rating stop cleanly instead of hammering the covers.
