Airtac MAC Stainless Steel Mini Air Cylinder MAC20X30SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X30SCM 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 MAC20X30SCM
Round-ended and offering just 30 mm of stroke, the MAC20X30SCM is the compact pusher you bolt in where panels are tight. Double acting and cushioned at both ends, it makes 157 N on extend and 131.9 N on retract at 0.5 MPa; halving the 16 kg lift equivalent leaves about 8 kg of vertical lifting with margin.
The CM round-end back cover suits pivot-pin installations, while FA flange, LB foot or SDB pivot brackets cover fixed setups. Stainless barrel plus a hard-chrome 8 mm rod stand up to splash and dust, and the built-in magnet reads position through CMSG / DMSG / EMSG switches without any special order.

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 MAC20X30SCM Is Used
Label press roller
Presses a labelling roller against bottles for a 30 mm dwell; 157 N at 0.5 MPa gives even nip pressure.
Panel latch pusher
The round CM cover pins to a linkage that latches enclosure doors on a 30 mm throw.
Part-present stopper
Stops small components at a vision station and confirms position via a CMSG switch on the standard magnet.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X30SCM the Right Cylinder?
Force ladder at 0.5 MPa: 100.5 N for the 16 mm bore, 157 N here, 245.3 N at 25 mm. If your part needs holding under power loss, remember a plain MAC drifts - a rod lock or pilot check valve does that job instead. Plumb it via the 1/8" port - PT blank as standard, G or NPT by code - with M8x1.25 male rod thread for tooling.
Mounting choices run from the CM round-end back cover to FA flange, LB foot and SDB pivot brackets, and I or Y rod knuckles connect the working end. Thirty millimetres of stroke keeps rod-bending risk low, and the standard magnet means CMSG / DMSG / EMSG switches work from day one.
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 MAC20X30SCM FAQ
Extend force is 157 N and retract 131.9 N at 0.5 MPa; at 0.7 MPa they become 219.8 N and 184.7 N. The theoretical maximum is close to 32 kgf at 1.0 MPa. Feed it 0.15-1.0 MPa (22-145 psi) and cycle at 30-800 mm/s.
Both ends have a variable air cushion controlled by needle screws. Open them fully before the first cycles, then close gradually until the 30 mm stroke lands softly - that way faster speeds or heavier parts stop without hammering the covers.
