Airtac MAC Stainless Steel Mini Air Cylinder MAC16X20SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC16X20SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø16mm bore and 20mm stroke, M5×0.8 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 MAC16X20SU
Flat-ended and slim, the U back cover on the MAC16X20SU bolts directly against plates and brackets, ideal where a protruding pivot eye would foul the housing. Pushing 100.5 N at 0.5 MPa and retracting at 86.4 N on a 6 mm hard-chrome rod, it is double acting and cushioned variably at both ends.
Its rolled stainless barrel plus hard-chromed rod resists the splash and humidity found in food benches and outdoor gates, an edge over coated-steel mini cylinders. Keep a 2:1 margin and the bore lifts about 5 kg vertically, or do real work with roughly 60 N at 0.5 MPa. The magnet comes built in, so CMSG, DMSG and EMSG switches drop on out of the box.

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 (Ø16mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 101 N | 86 N |
| 0.7 MPa | 141 N | 121 N |
| Max (@1.0 MPa) | 21 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 MAC16X20SU Is Used
Tripping a limit switch in a control panel door
The flat U cover mounts flush inside the panel frame, and the standard magnet provides a second sensing point without wiring a separate sensor.
Toe-clamping PCB fixtures on a reflow bench
Around 60 N of usable thrust clamps light fixtures without crushing, and the 20 mm stroke keeps the cycle under a second at 800 mm/s.
Pushing tea-bag bundles into carton pockets
Gentle dual-end cushioning seats bundles squarely, while the corrosion-resistant barrel copes with the damp wipe-downs of a packing hall.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC16X20SU the Right Cylinder?
When 100.5 N at 0.5 MPa leaves no headroom, step up to the 20 mm bore with 157.0 N; there is nothing smaller in the MAC range than this 16 mm bore. Since there is no spring return, a de-energised valve leaves the rod floating to the load, so spec a check valve or rod lock where the position must be retained. The U flat end suits direct plate bolting, with FA flange, LB foot or SDB pivot brackets available, and the M6x1.0 rod thread takes I or Y knuckles.
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 MAC16X20SU FAQ
Push is 100.5 N and pull 86.4 N at 0.5 MPa; at 0.7 MPa expect 140.7 N and 120.9 N, with 20.5 kgf the theoretical ceiling at 1.0 MPa. The rod is 6 mm with M6x1.0 male thread, the air port is M5x0.8, and operating pressure spans 0.15-1.0 MPa (22-145 psi).
The stainless tube and 20 um hard-chrome rod shrug off condensation, cleaning agents and outdoor exposure, and the riveted rolling-packed body keeps its seal where painted-steel bodies chip and rust. It also stays compact and self-supporting without tie rods.
