Airtac MAC Stainless Steel Mini Air Cylinder MAC20X190SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X190SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 190mm 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 MAC20X190SU
A flat-end U back cover gives the MAC20X190SU a clean fixed face for direct screw-down mounting, wrapped around a 20 mm bore and a 190 mm stroke. This is a double-acting cushioned mini: 157 N push and 131.9 N pull at 0.5 MPa, climbing to 219.8 N push at 0.7 MPa, with a theoretical 32 kgf at 1.0 MPa. It runs on 0.15-1.0 MPa (22-145 psi) filtered air at 30-800 mm/s.
Wet or dusty corners are where the stainless barrel earns its keep - mild corrosion and washdown do not threaten it the way they do painted housings. Practically, budget around 94 N of thrust for real work at 0.5 MPa, which hoists about 8 kg vertically with a 2:1 safety factor; a counterweight or spring assist stretches that reach further.

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 MAC20X190SU Is Used
Screwdriver feed on a bench rig
Advancing a self-tapping driver 190 mm into plastic housings; the flat U cover face screws straight onto the slide plate with no adapter.
Water-test lance extension
Pushing a rinse nozzle into a wash tank cycle - stainless construction shrugs off constant splash where coated barrels would pit.
Crimp anvil positioning
Setting a light pre-crimp on cable lugs before final press, tuned with the variable cushion so the anvil settles without bounce.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X190SU the Right Cylinder?
For lighter duties a 16 mm bore returns 100.5 N at 0.5 MPa; when the 245.3 N of a 25 mm bore is closer to the mark, upsize instead. On a 190 mm stroke keep thrust axial - side loads bend an 8 mm rod. The piston will not park itself: when supply bleeds or the valve sits neutral, expect drift, so fit a rod lock or check valve for a held stop. The U flat-end cover bolts flush to a machine face, the standard magnet pairs with CMSG / DMSG / EMSG switches, and LB foot or FA flange brackets convert it to body mounting.
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 MAC20X190SU FAQ
Push is 157 N and pull 131.9 N at 0.5 MPa; at 0.7 MPa push is 219.8 N and pull 184.7 N; theoretical peak 32 kgf at 1.0 MPa. Supply 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s, with the cushion adjustable at both ends.
Every cylinder of this series ships with an internal magnet, so CMSG, DMSG and EMSG reed or Hall switches clamp onto the 20 mm barrel at any position along the 190 mm stroke - no magnet option to pay for and no disassembly to fit them.
