Airtac MAC Stainless Steel Mini Air Cylinder MAC20X20SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X20SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm 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 MAC20X20SCA
The CA pivot back cover on this 20 mm bore MAC lets the whole cylinder swing on a pin, so linkage motion stays true without extra brackets. Double acting with a variable air cushion at both ends, it pushes 157 N and pulls 132 N at 0.5 MPa - call it roughly 94 N of honest working force, or about 8 kg of vertical lift. At 0.7 MPa the push climbs to 220 N.
Inside is a rolled stainless barrel with a hard-chrome 8 mm rod, a build that outlasts painted minis in damp or washed-down corners. The 20 mm stroke suits short clamp-and-release moves at 30-800 mm/s, and the standard-fit magnet picks up CMSG, DMSG or EMSG switches for position feedback.

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 (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 132 N |
| 0.7 MPa | 220 N | 185 N |
| Max (@1.0 MPa) | 32 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 MAC20X20SCA Is Used
Swinging clamp arm
Clamping a bracket during PCB soldering - the CA pivot lets the arm follow the lever arc while 157 N at 0.5 MPa holds the joint.
Flap gate diverter
Tipping a small flap on a coffee-roaster discharge chute; a 20 mm throw is enough and the cushion tames the flap at both ends of the swing.
Carton flag kicker
Flipping a reject flag on a carton line, with a CMSG switch on the standard magnet confirming every kick.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X20SCA the Right Cylinder?
Twenty millimetres of stroke and 157 N at 0.5 MPa: drop to a 16 mm bore (100.5 N) for lighter work or step to 25 mm (245.3 N) if the load is stiff. Because the piston drifts when supply air is cut, fit a pilot check valve or rod lock wherever the clamped part must stay gripped. The pivot back cover handles swinging mounts; FA flange, LB foot or SDB pivot brackets cover fixed ones. Ports are 1/8" on every 20 mm bore MAC.
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 MAC20X20SCA FAQ
Push is 157 N and pull 132 N at 0.5 MPa; at 0.7 MPa expect 220 N and 185 N, peaking at 32 kgf theoretical at 1.0 MPa. It runs on 0.15-1.0 MPa (22-145 psi), survives 1.5 MPa (215 psi) proof, moves at 30-800 mm/s and works from -20 to +70 C. Ports are 1/8"; the rod is 8 mm with an M8x1.25 male thread.
Yes - every MAC carries a built-in magnet as standard regardless of back cover, so CMSG, DMSG and EMSG switches drop straight onto the barrel. No special piston or retrofit is needed.
