Airtac MAC Stainless Steel Mini Air Cylinder MAC20X180SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X180SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 180mm 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 MAC20X180SU
A flat-end U back cover and 180 mm stroke define the MAC20X180SU, a 20 mm bore double-acting mini cylinder in AirTAC's riveted round-body format. Air powers the rod both ways - 157 N out at 0.5 MPa, 131.9 N back - and twin variable cushions temper the end of every cycle, even at the full 800 mm/s.
The rolled stainless barrel keeps a sealed, rigid body through washdown and outdoor duty where painted minis corrode, and the hard-chrome 8 mm rod resists rust and scoring. Expect about 94 N of genuine working push at 0.5 MPa, equal to roughly 8 kg hoisted vertically with a two-fold margin, with the magnet fitted as standard for CMSG, DMSG or EMSG switches.

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 MAC20X180SU Is Used
Capsule lid tamp head
Presses foil lids onto coffee capsules at a rotary sealer; 157 N at 0.5 MPa seats each lid while the cushion removes the final thump.
Tote latch release
Releases spring latches on totes inside a compact vertical lift module, reaching 180 mm into the rack pocket.
Welding jig clamp
Clamps bracket plates square in a small welding fixture; about 94 N of working force holds parts steady while the gun fires.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X180SU the Right Cylinder?
A sizing check puts 157 N of push at 0.5 MPa above the 16 mm bore (100.5 N) and below the 25 mm bore (245.3 N) within the same round MA family. It runs 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s, plumbed through 1/8" ports with an M8x1.25 male rod thread.
The U flat-end cover attaches to fixed plates with no bracket in between; FA flange, LB foot or SDB pivot hardware bolts on when the layout calls for it. Across 180 mm of stroke, guide the payload externally, because lateral hits will bow the 8 mm rod. And since the rod settles under gravity the moment air vents, order a rod lock or pilot check valve wherever a mid-stroke hold is part of the cycle.
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 MAC20X180SU FAQ
On the 20 mm bore: 157 N push and 131.9 N pull at 0.5 MPa, 219.8 N push and 184.7 N pull at 0.7 MPa, and a theoretical 32 kgf maximum at 1.0 MPa. Usable continuous push works out near 94 N, equal to hoisting about 8 kg vertically with a 2:1 margin.
The rolled stainless tube with riveted aluminium covers and a hard-chrome 8 mm rod takes repeat washdown, condensation and outdoor weather without flaking paint into your product. The magnet is built in as standard, so CMSG, DMSG or EMSG switches mount directly for end-of-stroke feedback, and 1/8" ports accept PT, G or NPT fittings.
