Airtac MAC Stainless Steel Mini Air Cylinder MAC20X300SCAFA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X300SCAFA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 300mm 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 MAC20X300SCAFA
With 157 N of push and 131.9 N of pull at 0.5 MPa, the MAC20X300SCAFA stretches a 20 mm bore across a 300 mm stroke and bolts down through an FA flange while the CA back cover still carries a pivot eye. Air works both chambers, and a variable cushion at each end soaks up end-of-stroke shock so faster cycles do not hammer the covers.
The rolled stainless barrel and hard-chrome plated rod resist corrosion in wet or outdoor spots far better than painted minis. Keep real working force near 94 N at 0.5 MPa - 60 percent of rating - enough to raise roughly 8 kg vertically with a 2:1 margin, or 16 kg ignoring the margin. The magnet fitted as standard accepts CMSG, DMSG and EMSG switches right out of the box; pressure range 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s.

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 MAC20X300SCAFA Is Used
Pick-up elevator in an assembly cell
The flange holds the body plumb while the rod raises an 8 kg fixture between stations; the 300 mm lift matches a two-tier cell layout.
Sliding gate on a paint line
Flange-mounted at the booth wall, it pushes a 300 mm spray-zone gate open and closed; the stainless barrel shrugs off overspray and solvent wipe-downs.
Flap tucker on a packing bench
Folds bottom carton flaps before taping; 94 N of steady push at 0.5 MPa seats corrugated flaps without crushing the box.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X300SCAFA the Right Cylinder?
Compare the 16 mm bore (100.5 N at 0.5 MPa) if the load is light, or step to 25 mm (245.3 N) for heavier clamping. The FA flange fixes the body rigidly; use the CA pivot eye only if the linkage swings. A 300 mm rod will bend under side load, so guide the payload externally rather than leaning on the piston rod. A centred valve or lost air leaves the rod free to coast - add a rod lock or pilot check valve to pin it.
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 MAC20X300SCAFA FAQ
Push 157 N and pull 131.9 N at 0.5 MPa; 219.8 N push and 184.7 N pull at 0.7 MPa; 32 kgf theoretical maximum at 1.0 MPa. Air ports are 1/8", the rod thread is M8x1.25, and the 300 mm stroke sits inside the 500 mm standard range for a 20 mm bore.
The flange bolts the cylinder body to a flat surface, keeping the 300 mm rod aligned over its full travel - useful on long pushes where a pivot-only mount would sway. The CA pivot eye remains on the back cover, and the standard magnet works with CMSG or EMSG switches.
