Airtac MAC Stainless Steel Mini Air Cylinder MAC20X30SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X30SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 30mm 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 MAC20X30SU
Short and direct, the MAC20X30SU suits frames where 30 mm of travel is all there is. Double acting - air both extends and retracts the rod - it pushes 157 N at 0.5 MPa and 219.8 N at 0.7 MPa, with a variable air cushion at each end to tame the stop.
The riveted stainless-steel barrel and hard-chrome plated rod laugh off humidity and light washdown, a real edge over painted minis in food frames. Its U flat-end back cover sits flush against machine plates with no pivot hardware. In practice, plan on about 94 N of usable work (six tenths of the rating) and expect the bore to lift roughly 8 kg vertically 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 MAC20X30SU Is Used
Reject gate on a bottle filler
Flicks off-spec glass bottles out of a filling lane; the 30 mm stroke matches the gate throw and 157 N clears a full bottle with ease.
Bench stamping jig
Dimples and marks terminal blocks in a small press jig, working well within the roughly 94 N continuous figure.
Index confirm on a rotary table
The built-in magnet trips a DMSG switch at each end of the short stroke to confirm the divider index.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X30SU the Right Cylinder?
If 157 N at 0.5 MPa overshoots your load, the 16 mm bore pushes 100.5 N; when the job grows, the 25 mm bore reaches 245.3 N at the same pressure. This cylinder will not hold position on its own - with the valve centred or air lost, the rod drifts - so add a rod lock or pilot check valve where a load must stay put. The magnet is factory fitted, so CMSG, DMSG or EMSG switches drop straight on, and 1/8 inch PT ports keep plumbing simple; specify G or NPT thread in the code if preferred.
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 MAC20X30SU FAQ
At 0.5 MPa it pushes 157 N and pulls 131.9 N. At 0.7 MPa the figures rise to 219.8 N push and 184.7 N pull, and the theoretical peak at 1.0 MPa is 32 kgf. For continuous duty, size around 94 N.
Back both cushion needle screws fully off before start-up, then close them gradually until the stroke lands quietly across the 30-800 mm/s speed range. The cylinder runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi).
