Airtac MAC Stainless Steel Mini Air Cylinder MAC32X40SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X40SCA 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 MAC32X40SCA
The MAC32X40SCA pairs a 40 mm stroke with AirTAC's round-body stainless barrel and a hard-chrome plated rod, a build that shrugs off washdown and damp shop air far better than painted-steel minis. Double acting on both strokes, it carries a variable air cushion at each end - back the needle screws off on first run and open them gradually to soak up end-of-stroke shock at speeds up to 800 mm/s.
At 0.5 MPa this 32 mm bore pushes 402 N and pulls 346 N; at 0.7 MPa push rises to 563 N. For long seal life, plan real work around 240 N rather than the full rating - that headroom is what keeps the cushion rings healthy. The magnet comes built in, so a CMSG or DMSG switch snaps onto the barrel without a special-order piston, and the CA pivot back cover accepts a pivoting mount straight off the shelf.

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 MAC32X40SCA Is Used
Dairy tray push-off
Shifts filled yoghurt trays between washdown conveyor lanes at a dairy, where the stainless barrel tolerates daily hose-down.
Drill jig clamp
Clamps aluminium housings in a CNC drill fixture, holding parts with about 240 N of continuous clamp force at 0.5 MPa.
Parcel chute diverter
Swings sortation chute gates at a courier hub, with CMSG switches signalling gate-open and gate-closed positions.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X40SCA the Right Cylinder?
Size it both ways before committing: the 25 mm bore delivers 245 N push at 0.5 MPa while stepping up to 40 mm buys 628 N, so the 32 mm at 402 N is a balanced middle choice for clamping and push-off work. Like any double-acting cylinder without a rod lock, the rod drifts if air is lost - add a pilot check valve or rod lock where the load must stay put. LB foot or FA flange brackets plus I and Y rod knuckles bolt on, and the 12 mm rod handles in-line loads well at this short 40 mm stroke.
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 MAC32X40SCA FAQ
At 0.5 MPa it pushes 402 N and pulls 346 N; at 0.7 MPa push is 563 N and pull 484 N, with a theoretical maximum of 82 kgf at 1.0 MPa. Working pressure spans 0.15-1.0 MPa (22-145 psi), proof pressure is 1.5 MPa (215 psi), and rod speed runs 30-800 mm/s through 1/8" ports.
No - the magnet is fitted as standard on every MAC32X40SCA, so CMSG, DMSG and EMSG switches clip onto the stainless barrel and read end-of-stroke positions immediately. The male rod thread is M10x1.25 on a 12 mm rod, making linkage and sensor-side setup straightforward.
