Airtac MAC Stainless Steel Mini Air Cylinder MAC32X12SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X12SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 12mm 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 MAC32X12SCA
Twelve millimetres is all the travel some jobs need, and this bore still throws 402 N of push at 0.5 MPa across that short span - plenty to clamp, eject or press-check without a lever mechanism. It is double acting, variably cushioned at both ends, and cycles happily from 30-800 mm/s on filtered air at 0.15-1.0 MPa (22-145 psi).
The CA back cover carries a pivot that follows slight misalignment in the machine frame, saving shimming work on retrofit installs. Build quality comes from the rolled construction - stainless barrel, aluminium covers, stainless block - with a 20 um hard-chrome finish on the 12 mm carbon-steel rod. A magnet is fitted as standard, so CMSG / DMSG / EMSG switches report clamp state from day one. As a rule of thumb, count on about 241 N of usable push at 0.5 MPa, close to a 20 kg vertical lift with a 2:1 margin.

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 MAC32X12SCA Is Used
Clamp on a small CNC fixture
A link-style clamp actuator grips a machined blank with 402 N at 0.5 MPa; the 12 mm stroke matches quick-release linkages and the CA pivot absorbs fixture misalignment.
Ejector on an electronics bench
Finished boards are nudged off a nest by 12 mm of travel; an EMSG switch wired to the built-in magnet confirms ejection before the pick-and-place returns.
Date-code stamp on a packing bench
A stamp head touches cartons briefly at up to 800 mm/s; the short stroke keeps cycle time low and the chrome rod resists ink and solvent splash.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X12SCA the Right Cylinder?
Force sits mid-range in the MAC family: a 25 mm bore makes 245.3 N at 0.5 MPa and a 40 mm bore makes 628.3 N, so 32 mm suits clamps that need real grip without a bulky body. Remember the rod is not spring-held - when air vents or the valve centres it will move with the load, so use a pilot check valve or rod lock where the clamp must stay shut. The CA pivot pairs naturally with an I or Y rod knuckle for linkage clamping, while FA flange, LB foot and SDB pivot brackets remain on the menu for frame mounting.
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 MAC32X12SCA FAQ
Stroke does not change force: at 0.5 MPa the 32 mm bore pushes 402 N and pulls 345.6 N; at 0.7 MPa, 563 N push and 483.8 N pull; theoretical maximum 82 kgf at 1.0 MPa. Ports are 1/8", the rod is 12 mm with an M10x1.25 thread, and the piston magnet is standard.
The pivot lets the cylinder swing slightly to follow misalignment between fixture and clamp arm, cutting side load on the 12 mm rod. Add an I or Y knuckle on the rod and the linkage stays free; the riveted stainless barrel and variable cushions come exactly as on every other MAC.
