Airtac MAC Stainless Steel Mini Air Cylinder MAC20X60SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X60SU 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 MAC20X60SU
The MAC20X60SU pairs a 20 mm bore with a 60 mm stroke in a round stainless-steel barrel that is rolled onto its aluminium covers, giving a riveted body that shrugs off washdown better than painted mini cylinders. Double acting with a variable air cushion at each end, it pushes 157 N and pulls 131.9 N at 0.5 MPa; the forward force climbs to 219.8 N at 0.7 MPa.
The U flat-end back cover lets you bolt the body flat against a machine plate with no pivot hardware, and the built-in magnet means CMSG, DMSG or EMSG switches clip on as standard, not as a special order. Sized realistically, expect about 94 N of usable work at 0.5 MPa - enough 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 MAC20X60SU Is Used
Indexing table unlock
Extending and retracting locking pins on a rotary indexing table, where the 60 mm stroke clears a 40 mm pin and the cushion tames the snap at each end.
Reject gate push-off
Kicking misaligned bottles off a bottling line conveyor; about 94 N of working force moves light containers briskly within the 30-800 mm/s speed band.
Snap-lid press-down
Pressing snap-on lids onto small tubes in a packaging cell; the variable cushion stops the ram hammering when the lid seats.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X60SU the Right Cylinder?
If 157 N at 0.5 MPa is more than the job needs, the 16 mm bore gives 100.5 N in the same family; step up to a 25 mm bore when you need 245.3 N. Remember the MAC20X60SU drifts when air is removed - add a rod lock or pilot check valve if the load must stay put. For pivoting motion, order the CA pivot or SDB bracket variant instead of this fixed U end.
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 MAC20X60SU FAQ
At 0.5 MPa it pushes 157 N and pulls 131.9 N; at 0.7 MPa the figures are 219.8 N push and 184.7 N pull, with a theoretical maximum of 32 kgf at 1.0 MPa. Keep real duty near 94 N and it will lift about 8 kg vertically with margin. Ports are 1/8" PT, the rod is 8 mm with an M8x1.25 male thread, and 60 mm is a standard stroke.
The barrel is stainless steel and the rod is hard-chrome plated carbon steel, rolled into aluminium covers, so the body resists mild corrosion where painted minis would flake. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi) from -20 to +70 C.
