Airtac MAC Stainless Steel Mini Air Cylinder MAC20X100SUFA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X100SUFA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 100mm 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 MAC20X100SUFA
Flange it and forget alignment: the FA mount squares the MAC20X100SUFA against a machine face so the 8 mm rod stays true through its 100 mm stroke. At 0.5 MPa expect 157 N of push and 132 N of pull from this double-acting body. Keep practical effort near 94 N, about six tenths of the rating, and the seals and mounts last far longer.
The barrel is rolled stainless steel around aluminium covers, with the carbon-steel rod hard-chrome plated 20 um deep - a package that tolerates rinse-down and damp air far better than painted minis. Cushioning is variable air at both ends, and the built-in magnet is standard equipment, ready for CMSG, DMSG or EMSG switches without a special order.

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 MAC20X100SUFA Is Used
Bearing press fit
Presses small bearings into pump housings on an assembly bench, the flange keeping thrust in line with the 8 mm rod.
Carton flap tuck
Tucks end flaps on a semi-auto cartoner running snack packs, variable cushions quieting the tuck at 157 N of push.
Sample elevator
Raises sample racks of about 8 kg vertically in a lab autoloader, an EMSG switch on the standard magnet signaling top position.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X100SUFA the Right Cylinder?
If 157 N at 0.5 MPa feels thin for the job, the 25 mm bore offers 245 N; if it is overkill, the 16 mm bore still gives 100 N. Remember this cylinder cannot park a load on lost air - the piston drifts until a pilot check or rod lock is fitted. The FA flange suits fixed inline thrust; choose the SDB pivot bracket instead if the load follows an arc, and drive it at 30-800 mm/s on 0.15-1.0 MPa (22-145 psi) filtered air.
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 MAC20X100SUFA FAQ
At 0.5 MPa: 157 N push, 132 N pull. At 0.7 MPa: 220 N push. Theoretical maximum at 1.0 MPa: 32 kgf. Operating band 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), port size 1/8 inch, bore 20 mm, stroke 100 mm.
No. Every MAC cylinder ships with the magnet already in the piston, so CMSG, DMSG or EMSG switches clamp straight onto the barrel and wire up like any standard sensor - no special-order piston needed.
