Airtac MAC Stainless Steel Mini Air Cylinder MAC32X20SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X20SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 20mm 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 MAC32X20SCM
Short-stroke marking, staking and riveting is where MAC32X20SCM earns its keep: a 32 mm bore, 20 mm stroke and 402 N of push at 0.5 MPa, double acting with a variable air cushion to soften the strike at each end.
The CM round-end back cover presents a compact fixed mounting face, and the riveted stainless body - barrel plus hard-chrome rod - shrugs off the coolants and splashes that peel paint off ordinary minis. Speed is metered anywhere from 30 to 800 mm/s, and since the magnet comes as standard, CMSG, DMSG and EMSG switches bolt on without a special piston. Treat about 241 N as your continuous working force and the seals will thank you.

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 MAC32X20SCM Is Used
Pad stamping on date coders
A 20 mm plunge drives a numbering head into cartons at up to 800 mm/s, with the cushion damping the impact.
Riveting terminals on a loom bench
The rod sets crimp terminals with 402 N of force while the adjustable cushion keeps the strike quiet.
Part seating under a pick station
Rounds parts fully into their nests after a robot pick, working on roughly 241 N of sustained push.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X20SCM the Right Cylinder?
Compare at 0.5 MPa: 25 mm gives 245 N and 40 mm gives 628 N, so 32 mm at 402 N sits squarely in light-press territory. This cylinder will not hold a position when air is removed - the piston floats - so use a pilot check valve or rod lock where a stamped part must stay clamped. The round-end cover suits direct fixed mounting; add FA flange, LB foot or SDB pivot brackets, or I and Y rod knuckles for the tooling side.
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 MAC32X20SCM FAQ
At 0.5 MPa: 402.2 N push, 345.6 N pull. At 0.7 MPa: 563.0 N push (483.8 N pull). Theoretical maximum 82 kgf at 1.0 MPa. Bore 32 mm, stroke 20 mm, 12 mm rod with M10x1.25 thread, 1/8 in ports, 0.15-1.0 MPa (22-145 psi) pressure, 30-800 mm/s speed.
It is a rolled, riveted round-body cylinder: a stainless-steel barrel with aluminium-alloy covers and a stainless block packed onto it, plus a 20 um hard-chrome plated carbon-steel rod. The piston seal is a two-way design that also stores grease, keeping friction low through repeated short cycles.
