Airtac MAC Stainless Steel Mini Air Cylinder MAC20X60SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X60SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 60mm 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 MAC20X60SCM
Short strokes do not have to mean hard stops, and the MAC20X60SCM proves it: 60 mm of double-acting travel with a variable air cushion at each end, all inside a stainless round barrel built to order in standard lengths up to 500 mm for this bore. Push is 157 N and pull 131.9 N at 0.5 MPa, which works out to roughly 94 N of real working force after reserve, or a vertical lift of about 8 kg with a 2:1 margin for a small fixture or part.
The CM round-end back cover offers a compact pivoting mount for linkages and levers, while the hard-chrome plated rod and rolled stainless tube handle damp shops and periodic washdown without the rust of painted minis. The magnet sits in the piston as standard equipment, so CMSG / DMSG / EMSG switches snap on the barrel the moment feedback is required.

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 MAC20X60SCM Is Used
Bushing press on a small housing line
Seating light bushings into aluminium housings on a bench press, where about 94 N of working force at 0.5 MPa suits plastic and thin press fits.
Indexed test slide for electronics
Advancing test probes onto circuit boards in 60 mm moves, with a CMSG switch at each end confirming the probe is fully clear before cycling.
Flap tucker on a case erector
Folding bottom box flaps on a carton erecting machine, with the cushion easing the flap home and the pivot cover handling the folding linkage.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X60SCM the Right Cylinder?
Sizing context: the 157 N push at 0.5 MPa doubles the 100.5 N of bore 16 and sits well under the 245.3 N of bore 25, so this is the sweet spot for small presses and light gates. There is no inherent lock in the MAC; with air off or the valve centred the piston moves freely, so a held position calls for a rod lock or pilot check valve. For the 60 mm stroke, side loads are modest, though guiding the load is still wise if the tooling is long or cantilevered. Add FA flange, LB foot or SDB pivot brackets to the CM cover as the frame allows; the standard magnet works with every CMSG / DMSG / EMSG switch in the range.
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 MAC20X60SCM FAQ
Push 157 N and pull 131.9 N at 0.5 MPa; push 219.8 N and pull 184.7 N at 0.7 MPa; theoretical maximum 32 kgf at 1.0 MPa. Supply 0.15-1.0 MPa (22-145 psi) of 40 um filtered air, speed 30-800 mm/s, 1/8" ports, 8 mm rod with M8x1.25 thread, 60 mm standard stroke.
The magnet is standard in every piston, so switch feedback is not a special-order item. Mount a CMSG, DMSG or EMSG reed or hall switch directly on the stainless barrel, and the cushion needle screws let you slow the approach so the switch reads a clean, repeatable signal.
