Airtac MAC Stainless Steel Mini Air Cylinder MAC32X140SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X140SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 140mm 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 MAC32X140SU
Rated for 402.2 N push at 0.5 MPa and 345.6 N pull, the 32 mm bore in this 140 mm stroke MAC covers mid-weight clamping, pushing and lifting in one compact round body. Double-acting by design, it runs anywhere from 30 to 800 mm/s, and the variable air cushion at both ends is dialled in with the needle screws so heavy loads never slam the aluminium covers.
Construction is the classic MA recipe: a stainless-steel barrel rolled into the covers around a grease-retaining piston seal, plus a hard-chrome plated rod that shrugs off corrosion. Plan real work at about 241 N, six-tenths of the rated push, and the unit will run cool and consistent across long shifts. The U back cover presents a flat fixed face for direct bolting, and the standard magnet pairs with CMSG, DMSG or EMSG switches out of the box.

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 MAC32X140SU Is Used
Case glue press
Pressing glue-flap cases closed on a cartoning line; 402 N keeps the flaps seated while the adhesive cures, with cycle speeds anywhere in the 30-800 mm/s band.
Sorter diverter gate
Actuating a diverter gate on a parcel sorter, with CMSG switches confirming gate position to the PLC before each parcel passes.
Cutoff saw length stop
Setting the length stop on an aluminium cutoff saw; the flat U back cover bolts straight to the machine frame with no extra brackets.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X140SU the Right Cylinder?
Downsize to the 25 mm bore (245.3 N at 0.5 MPa) or upsize to the 40 mm bore (628.3 N) depending on the load; this 32 mm size carries 402.2 N push / 345.6 N pull. It operates on 0.15-1.0 MPa (22-145 psi) of air filtered to 40 um. Keep in mind the piston floats when air is removed - cushions slow the stroke, they never hold it - so fit a rod lock or pilot check valve for any suspended load. Mount via the flat U cover directly or add FA flange, LB foot or SDB pivot hardware; I and Y rod knuckles are also on the option list. At 140 mm, keep the rod square to the load to avoid bending.
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 MAC32X140SU FAQ
Expect 402.2 N push and 345.6 N pull at 0.5 MPa, 563.0 N push and 483.8 N pull at 0.7 MPa, and 82 kgf theoretical maximum at 1.0 MPa. Pressure may run 0.15-1.0 MPa (22-145 psi) with a proof strength of 1.5 MPa (215 psi).
No. The magnet is built into the piston as standard on every MAC, so CMSG, DMSG or EMSG switches mount directly on the barrel without a special-order cylinder. That makes end-of-stroke or mid-stroke confirmation a plug-on accessory rather than a custom build.
