Airtac MAC Stainless Steel Mini Air Cylinder MAC20X160SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X160SU 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 MAC20X160SU
With a flat-end U back cover machined for direct face mounting, the MAC20X160SU trades brackets for simplicity: bolt the cover to your fixture, connect the 1/8" ports and the 8 mm hard-chrome rod goes to work. Double-acting movement with a variable air cushion at both ends lets this 20 mm bore run 30-800 mm/s across 0.15-1.0 MPa (22-145 psi) air, delivering 157 N of push and 132 N of pull at 0.5 MPa.
The riveted stainless barrel shrugs off washdown splash and damp workshop air that swells painted mini cylinders, and the standard-fit magnet accepts CMSG, DMSG or EMSG switches out of the box. Treat 157 N as the ceiling, not the target: plan jobs around 94 N at 0.5 MPa, or about 8 kg of vertical lift once you double the safety 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 MAC20X160SU Is Used
Bracket clinch station
Face-bolt the U cover to the station plate and clinch spring clips onto brackets; 220 N at 0.7 MPa gives headroom for stiff clips.
Carton flap tucker
Tuck leading flaps on small cartons as they pass a sealer - the 160 mm stroke reaches across the flap and the cushion quiets each hit.
Vision camera shuttle
Slide an inspection camera into position between shots; the built-in magnet drives a DMSG switch for in-position confirmation.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X160SU the Right Cylinder?
A 16 mm bore tops out near 100 N push at 0.5 MPa, so step up if you need the MAC20X160SU's 157 N; a 25 mm bore gives 245 N when the load grows again. Centre or exhaust the valve and the rod simply coasts - nothing holds it - so spec a rod lock or pilot check valve for suspended loads. The U flat-end cover suits face-bolted fixtures; add an FA flange or SDB pivot bracket if your mounting geometry changes.
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 MAC20X160SU FAQ
Push is 157 N and pull 132 N at 0.5 MPa; at 0.7 MPa that becomes 220 N push and 185 N pull, with a 32 kgf theoretical maximum at 1.0 MPa. It runs on 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s, uses 1/8" ports, and the 8 mm rod carries an M8x1.25 male thread.
The barrel is stainless steel rolled over the covers in a riveted pack, with a hard-chrome plated carbon-steel rod - a combination that resists washdown splash and humid air far better than painted mini cylinders.
