Airtac MAC Stainless Steel Mini Air Cylinder MAC32X125SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X125SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 125mm 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 MAC32X125SCM
A 32 mm bore pushing through a 125 mm stroke delivers 402 N (about 41 kgf) of forward force at 0.5 MPa, rising to 563 N at 0.7 MPa. This MAC runs double acting - air extends and retracts the rod - and a variable air cushion at both ends lets you bleed off end-of-stroke shock, so the round barrel can cycle anywhere from 30-800 mm/s without hammering its covers. Supply it filtered air between 0.15-1.0 MPa (22-145 psi).
The high-precision stainless barrel paired with a hard-chrome plated carbon-steel rod shrugs off washdown and damp shop air, a real edge over painted minis in food or outdoor cells. Since the piston carries a magnet as standard, CMSG / DMSG / EMSG switches clip straight on for end-of-stroke signalling. For sizing, plan on roughly 241 N of usable work at 0.5 MPa (about 60 percent of the rating), which is around 20 kg of vertical lift with a 2:1 margin. The CM round-end back cover bolts flat against fixed surfaces without an extra bracket.

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 MAC32X125SCM Is Used
Indexing a packaging conveyor
A 125 mm stroke steps cartons between lanes on a snack-food line; 402 N at 0.5 MPa drives the product stop, and the stainless barrel survives frequent wipe-downs.
Clamping a small welding fixture
Brackets and tubes clamp tight with up to 563 N at 0.7 MPa; the adjustable cushion damps clamp-in impact so the fixture does not shift out of square.
Tray eject in lab automation
Sample trays divert down a chute on demand, with a CMSG switch on the standard magnet confirming full ejection before the next rack is presented.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X125SCM the Right Cylinder?
At 0.5 MPa this bore pushes 402 N and pulls 345.6 N; a 25 mm MAC tops out at 245.3 N push, while a 40 mm bore reaches 628.3 N, so step down if your load stays under about 24 kgf. Like every double-acting MAC, the piston drifts when air is dropped - it holds no position - so fit a rod lock or pilot check valve where a load must hang. Over a 125 mm span keep the workpiece on its own linear guide; a 12 mm rod is not meant to carry side load, and bending it shortens seal life. The CM round back cover handles fixed mounting, and FA flange, LB foot or SDB pivot brackets are available if the frame needs them.
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 MAC32X125SCM FAQ
At 0.5 MPa the 32 mm bore pushes 402 N and pulls 345.6 N; at 0.7 MPa push rises to 563 N and pull to 483.8 N. The theoretical maximum is 82 kgf at 1.0 MPa. Stroke is 125 mm, ports are 1/8" PT, the rod is 12 mm and its male thread is M10x1.25.
The rolled CM cover presents a plain, flat end you can bolt straight to a machine plate, no adapter bracket needed. It is part of the same riveted body: stainless barrel, aluminium covers and a stainless block are rolled into one sealed round package, and the built-in magnet still accepts CMSG / DMSG / EMSG switches.
