Airtac MAC Stainless Steel Mini Air Cylinder MAC20X160SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X160SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 160mm 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 MAC20X160SCA
With 160 mm of stroke, the 20 mm bore still generates 157.0 N of push at 0.5 MPa - roughly 16 kgf - enough to swing or push light loads across a wide arc. The MAC20X160SCA is double acting with a variable air cushion at each end, so the long-moving rod can decelerate smoothly instead of slamming the aluminium covers. Air range is 0.15-1.0 MPa (22-145 psi) and rod speed reaches 800 mm/s.
The CA pivot back cover turns the cylinder itself into a linkage member: pin it to a lever and the rod eye rides the swing. Counting on a 60 percent duty figure leaves about 94 N of dependable push at 0.5 MPa, and in pure lift terms that thrust raises roughly 8 kg against gravity with a 2:1 margin. The riveted stainless barrel and hard-chrome rod tolerate splash and outdoor dust, and the built-in magnet feeds CMSG, DMSG or EMSG switches anywhere along the 160 mm.

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 MAC20X160SCA Is Used
Swing-arm gate diverter
Swinging a lightweight diverter gate on a packaging conveyor - the CA pivot pins straight to the lever over the 160 mm arc.
Sliding lid opener
Sliding a 4 kg machine cover 160 mm open; the cushion settles the lid at each end rather than crashing the stop.
Parts pusher across a tray
Advancing a row of blister packs onto an outfeed tray - about 94 N of practical push at 0.5 MPa keeps the row moving.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X160SCA the Right Cylinder?
Long strokes punish side loads, so guide the load externally - the 8 mm rod is meant for push-pull along its axis, not bending. If 157.0 N at 0.5 MPa feels tight, a 25 mm bore reaches 245.3 N; if generous, the 16 mm bore saves space at 100.5 N. Remember the rod position is not retained: with the valve centred or air off, the load drifts, so a pilot check valve or rod lock is the answer for held positions. Mount on the FA flange or LB foot and let the CA pivot carry the rod-end articulation; the magnet is fitted as standard.
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 MAC20X160SCA FAQ
The 20 mm bore pushes 157.0 N and pulls 131.9 N at 0.5 MPa, and 219.8 N / 184.7 N at 0.7 MPa, with a theoretical ceiling of 32 kgf at 1.0 MPa. It runs on 0.15-1.0 MPa (22-145 psi), survives 1.5 MPa (215 psi) proof, spans -20 to +70 C and strokes 160 mm at 30-800 mm/s.
Back both needle screws fully off, run the cylinder slowly through its 160 mm travel, then close them gradually until the end-of-stroke thump disappears. That leaves a variable cushion tuned to your load and speed - it slows the piston near each cover, it does not lock or hold it there.
