Airtac MAC Stainless Steel Mini Air Cylinder MAC20X230SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X230SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 230mm 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 MAC20X230SU
The MAC20X230SU pairs a 230 mm stroke with the cushioned 20 mm bore of AirTAC's round-body MA family. It is double acting - air both extends and retracts the rod - and a variable air cushion at each end soaks up the stop. At 0.5 MPa it develops 157 N of push and 131.9 N of pull, with speed adjustable across 30-800 mm/s.
The riveted stainless barrel and hard-chrome plated 8 mm rod shrug off washdown mist that blisters painted minis, a genuine edge in damp food and packaging corners. In practice, plan on roughly 94 N of the 157 N rating for real work so the mechanism keeps reserve; the standard built-in magnet accepts CMSG or DMSG switches 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 MAC20X230SU Is Used
Carton ejector
Ejects closed cartons from a checkweigher lane with about 94 N of working force, the air cushion softening the stop at full stroke.
Sample slide pusher
Pushes sample trays between test stations on a lab automation rail; the stainless barrel tolerates daily wipedown without rusting.
Small gate actuator
Swings a light interlock gate on a filling line; air retraction at 131.9 N resets the gate without any return spring.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X230SU the Right Cylinder?
If 157 N at 0.5 MPa overshoots the job, a 16 mm MAC gives 100.5 N push at the same pressure; when more muscle is needed, step up to a 25 mm bore for 245.3 N. Remember this cylinder drifts when air is removed - fit a pilot check valve or rod lock if the load must stay put with the valve centred. LB foot or FA flange brackets plus I or Y rod knuckles bolt on, and the standard magnet suits CMSG and DMSG switches. At 230 mm of stroke on an 8 mm rod, guide the load externally so side force never bends the rod.
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 MAC20X230SU FAQ
At 0.5 MPa it pushes 157 N and pulls 131.9 N; at 0.7 MPa those rise to 219.8 N and 184.7 N. Theoretical maximum at 1.0 MPa is 32 kgf. Pressure range is 0.15-1.0 MPa (22-145 psi) and speed 30-800 mm/s.
No. Every MA-series cylinder leaves the factory with a built-in magnet, so CMSG, DMSG and EMSG switches mount directly on the barrel for end-of-stroke signalling without a special-order piston.
