Airtac MAC Stainless Steel Mini Air Cylinder MAC20X65SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X65SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 65mm 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 MAC20X65SCA
157 N of push and 131.9 N of pull at 0.5 MPa - those are the working numbers for the MAC20X65SCA, a 20 mm bore, 65 mm stroke double-acting cylinder whose variable air cushions soak up end-of-stroke shock so you can run faster cycles without hammering the covers. Rising to 219.8 N at 0.7 MPa, it tops out at 32 kgf theoretical.
Its CA back cover carries a built-in pivot ear, so the cylinder swings on a clevis or pin with no extra brackets, while the stainless barrel and hard-chrome 8 mm rod take damp shop air in their stride. The magnet comes standard for CMSG, DMSG and EMSG switches. Plan on roughly 94 N of real work at 0.5 MPa, or a vertical lift of about 8 kg 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 (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 MAC20X65SCA Is Used
Hinged guard swing
Swinging a machine guard door on a pivot pin; the CA ear ties straight into the link and the cushion eases the door into its stop.
Sample tray lift
Raising small sample trays between lab automation stations; about 8 kg of vertical lift capacity covers loaded trays with margin to spare.
Glue-head retract
Pulling a hot-glue applicator head away from cartons on a case packer; 131.9 N of pull retracts the head briskly across 65 mm.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X65SCA the Right Cylinder?
Between the 16 mm bore (100.5 N at 0.5 MPa) and the 25 mm bore (245.3 N), this 20 mm barrel sits in the middle for light clamping and lifting. The CA pivot suits swing links and hinged tooling; add an FA flange or LB foot if you also need to fix the body. If a held position matters after air loss, fit a rod lock or pilot check valve - the cushion is not a brake. At 65 mm the stroke is standard for this bore, but keep side loads off the rod with an external guide.
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 MAC20X65SCA FAQ
Push is 157 N and pull 131.9 N at 0.5 MPa; at 0.7 MPa these become 219.8 N and 184.7 N, and the theoretical peak is 32 kgf at 1.0 MPa. The bore is 20 mm, ports are 1/8" PT, the rod is 8 mm with M8x1.25 male thread, and 65 mm is a standard stroke (this bore reaches 500 mm as standard). Speed is 30-800 mm/s on a 0.15-1.0 MPa (22-145 psi) supply.
No - every MAC20X65SCA ships with the magnet built in, so CMSG, DMSG or EMSG reed switches drop straight onto the barrel for end-of-stroke signalling without any special-order piston.
