Airtac MAC Stainless Steel Mini Air Cylinder MAC32X70SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X70SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 70mm 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 MAC32X70SCM
A riveted round body of stainless steel, a 12 mm hard-chrome rod and 402 N of push at 0.5 MPa - the MAC32X70SCM packs a bore 32 punch into a mini envelope. Air works both ways here: the cylinder is double acting, and its variable cushion at each end soaks up end-of-stroke shock when you raise speed or load.
The CM round-end back cover leaves a clean nose for custom fixtures, and the rolling-packed construction keeps the stainless barrel sealed against mild corrosion and washdown. The magnet comes built in as standard, so CMSG / DMSG / EMSG switches need no special-order piston. In practice expect about 240 N of working push at 0.5 MPa - roughly a 20 kg vertical lift on a 2:1 margin - with 82 kgf as the theoretical maximum.

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 MAC32X70SCM Is Used
Incubator sample shuttle
Sliding sample racks between two shelves inside a humid CO2 incubator, where stainless steel beats painted bodies.
Tile-press ejector
Ejecting pressed concrete tiles from a small mold bench, with the round-end cover adapting to the shop-built ejector plate.
Vial-fill position verify
Reporting fill-station head position on a pharmaceutical line via a CMSG switch reading the built-in magnet.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X70SCM the Right Cylinder?
Position sensing is where the SCM earns its keep: drop a CMSG switch into the barrel slot and the 70 mm stroke endpoints report back with no special piston order. Compared with a 25 mm bore at 245 N, this bore nearly doubles the push; a 40 mm bore would give 628 N if your frame and budget allow. Feed it 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s. Remember it is a plain double-acting cylinder: when the valve centres or air drops, the rod drifts, so fit a pilot check valve for held loads. FA flange or LB foot mounts suit fixed frames; SDB suits pivots.
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 MAC32X70SCM FAQ
Push 402 N and pull 346 N at 0.5 MPa; push 563 N and pull 484 N at 0.7 MPa; 82 kgf theoretical maximum. Bore 32 mm, rod 12 mm, port 1/8", rod thread M10x1.25, pressure 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s.
The stainless barrel with its riveted aluminium covers and hard-chrome carbon-steel rod resists mild corrosion and washdown, unlike painted minis. It is a rolled round-body design, not a tie-rod or profile cylinder, so it stays sealed in damp, food and outdoor settings.
