Airtac MAC Stainless Steel Mini Air Cylinder MAC20X110SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X110SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 110mm 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 MAC20X110SU
Flat-ended and only as wide as its 20 mm barrel, this double-acting MAC turns a 0.15-1.0 MPa (22-145 psi) supply into 157 N of extend force and 131.9 N of retract at 0.5 MPa; at 0.7 MPa the pair rises to 219.8 N and 184.7 N. Needle-adjustable cushions at both ends tame end-of-stroke impact across a 30-800 mm/s speed band, with proof pressure of 1.5 MPa (215 psi).
The round stainless tube resists corrosion in damp or lightly washed areas where painted mini bodies would rust, and the hard-chrome plated rod keeps sealing surfaces smooth over millions of cycles. A magnet comes fitted in the piston as standard, so CMSG, DMSG and EMSG switches read position without a special build. Practically, 157 N at 0.5 MPa supports around 94 N of continuous work, or about 8 kg of vertical lifting with a safety margin of 2:1.

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 MAC20X110SU Is Used
PCB magazine indexing
In electronics assembly, the flat-ended body slots behind a rail to index loaded PCB magazines in 110 mm steps, with the magnet feeding position signals to the controller.
Grain auger slide gate
A farm or feed mill can drive a small slide gate on an auger intake; the stainless barrel stands up to dust washdowns better than a painted body.
Dial table part stop
On an assembly dial table, the rod extends to stop a fixture at the unload station; cushions bring the moving fixture to a gentle halt each cycle.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X110SU the Right Cylinder?
Pick the U flat-end back cover when the body bolts flat against a machine face and no pivot is required. A 16 mm bore tops out at 100.5 N and a 25 mm bore starts at 245.3 N at 0.5 MPa, so this 20 mm barrel sits in the middle ground. The piston is free to drift the moment air is removed, so a rod lock or pilot check valve is the fix for loads that must stay parked. FA flange, LB foot and SDB pivot brackets can bolt on later if the mounting style 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 MAC20X110SU FAQ
At 0.5 MPa: 157 N extend and 131.9 N retract. At 0.7 MPa: 219.8 N extend and 184.7 N retract. Theoretical ceiling is 32 kgf at 1.0 MPa. Supply window is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-800 mm/s, with variable cushioning at both ends.
The rolled stainless barrel and hard-chrome plated carbon-steel rod stand up to humidity and light washdown far better than painted minis. Filtration to 40 um and a -20 to +70 C temperature range keep the seals happy indoors or out.
