Airtac MAC Stainless Steel Mini Air Cylinder MAC20X180SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X180SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 180mm 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 MAC20X180SCA
With 180 mm of travel on a 20 mm bore, the MAC20X180SCA pushes 157 N at 0.5 MPa and pulls 131.9 N, double acting with a variable cushion at each stroke end. Derated for dependable work that is about 94 N of push, or close to 8 kg lifted vertically with a 2:1 margin.
Its CA pivot back cover accepts a swinging link or clevis without bolt-on brackets, useful on linkage-driven fixtures. A riveted stainless barrel with a hard-chrome 8 mm rod stands up to damp and washed-down environments, and the standard piston magnet lets CMSG, DMSG or EMSG switches signal end positions with no special-order piston.

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 MAC20X180SCA Is Used
Carton flap swing arm
Swings a flap-folding arm on a small carton closer; the CA pivot suits the rotating linkage while 157 N folds two-layer board.
Conveyor stop gate
Pivots a stop gate out of the path of assembly trolleys on a lean-cell conveyor, with cushions so the gate never slams its stop.
Glassware wash tilt rack
Tilts a beaker-wash rack through 180 mm in a laboratory glasswasher, where the stainless barrel handles humid, rinsed conditions.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X180SCA the Right Cylinder?
Forces at 0.5 MPa come in at 157 N push and 131.9 N pull; a 16 mm bore offers 100.5 N if that is enough, and the 25 mm bore reaches 245.3 N when it is not. Speed spans 30-800 mm/s and pressure 0.15-1.0 MPa (22-145 psi). Bear in mind this cylinder cannot hold position on its own - with air gone or the valve centred the rod simply coasts - so hang suspended loads on a pilot check valve or rod lock.
Mount it pivoting on the CA cover or fixed with FA flange, LB foot and SDB hardware. Over a 180 mm stroke, align external guides with the 8 mm rod so it sees thrust only; ports are 1/8" and the male rod thread is M8x1.25.
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 MAC20X180SCA FAQ
Output on the 20 mm bore is 157 N push and 131.9 N pull at 0.5 MPa, rising to 219.8 N push and 184.7 N pull at 0.7 MPa; theoretical peak is 32 kgf at 1.0 MPa. Size links and structures for about 94 N of continuous push.
Back both needle screws fully open, cycle the rod slowly to each end, then close them a turn at a time until the 180 mm stroke lands without bounce. The cushion is variable rather than fixed, so you can retune it whenever speed or load changes within the 30-800 mm/s band.
