Airtac MAC Stainless Steel Mini Air Cylinder MAC32X20SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X20SCA 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 MAC32X20SCA
For jobs that need punch but little travel, MAC32X20SCA puts a 32 mm bore behind a 20 mm stroke. Double acting with a variable air cushion at both ends, it delivers 402 N of push at 0.5 MPa - enough to swing a clamp hard onto a workpiece and back without hammering either cover.
The CA pivot back cover lets the whole cylinder oscillate, so latches and swing clamps mount without extra linkage. Inside, a stainless barrel and hard-chrome rod laugh at coolant mist and washdown splashes. The built-in magnet is standard, so a CMSG or DMSG switch reads end positions straight out of the box. Matched to a real part, the push equals lifting roughly 41 kg vertically, or about 20 kg once you halve it for a 2:1 safety 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 MAC32X20SCA Is Used
Swing clamp on a welding fixture
A 20 mm turn and 402 N of push seats the clamp arm onto sheet-metal panels in an automotive jig.
Latching gate on a machine enclosure
The pivot cover lets the cylinder rock with the latch handle, applying 402 N of closing force at 0.5 MPa.
Part kicker at a sortation diverter
At 20 mm of throw the rod nudges small castings off a chute lane; the pull side returns it with 345 N.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X20SCA the Right Cylinder?
Size both ways from here: a 25 mm bore pushes 245 N at 0.5 MPa if the clamp is light, while a 40 mm bore at 628 N suits stiff clamping; 32 mm at 402 N covers most fixture work. If air pressure drops, the piston simply coasts - a clamp that must stay shut calls for a pilot check valve rather than this cylinder alone. On top of the CA pivot cover you can bolt an FA flange, LB foot or SDB pivot bracket, and the standard magnet accepts CMSG, DMSG and EMSG switches.
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 MAC32X20SCA FAQ
Push 402.2 N and pull 345.6 N at 0.5 MPa; 563.0 N push at 0.7 MPa; 82 kgf theoretical maximum at 1.0 MPa. Stroke is 20 mm, rod 12 mm with an M10x1.25 male thread, ports 1/8 in, pressure 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s, double acting with a variable cushion at each end.
The CA cover carries an integral pivot, so the cylinder can swing with a clamp arm or latch without added brackets. If the machine later needs a fixed mount, FA flange, LB foot and SDB pivot brackets fit the same body, and the magnet already built in supports CMSG, DMSG and EMSG switches.
