Airtac MAC Stainless Steel Mini Air Cylinder MAC20X200SUFA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X200SUFA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 200mm 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 MAC20X200SUFA
Bolt it down once and trust it: the FA flange on the MAC20X200SUFA removes alignment guesswork, fixing the 200 mm stroke true to the machine plate without a separate bracket. The 20 mm bore pushes 157 N at 0.5 MPa against a hard-chromed 8 mm rod inside a rolled, stainless barrel that stands up to splash and mild washdown where painted minis bubble and flake.
Cushioning is variable at both ends, so speeds up to 800 mm/s still land softly on the covers, and the standard magnet accepts CMSG, DMSG and EMSG switches anywhere along the barrel. For real work, count on about 94 N at 0.5 MPa - vertically that is roughly 8 kg lifted at a 2:1 margin, comfortably covering gates, lifts and pushers in this force class.

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 MAC20X200SUFA Is Used
Hopper gate lift
Raises a slide gate on a small ingredient hopper between batches; 200 mm of lift clears the outlet while the flange keeps the gate rails square.
Changeover pin puller
Retracts a locating pin on a machine changeover slide, the 132 N pull rating at 0.5 MPa easily winning against a light spring-assisted pin.
Deli-line tray denester
Pushes the bottom tray off a stack in a denesting head, one 200 mm stroke per cycle with the cushion damping the release.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X200SUFA the Right Cylinder?
If 157 N at 0.5 MPa overshoots your job, a 16 mm bore cuts force to 100.5 N; if it undershoots, a 25 mm bore jumps to 245.3 N. Keep in mind the rod will drift the moment air is removed - the cushion only softens arrival, it never locks - so pair a rod lock or pilot check valve with any load that must persist. The FA flange teams with LB foot or SDB pivot brackets and I/Y rod knuckles from the same accessory range. Ports are 1/8" and the rod thread is M8x1.25; 200 mm is a standard stroke here, well under the 500 mm ceiling for the bore.
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 MAC20X200SUFA FAQ
Extension force is 157 N at 0.5 MPa and retraction is 132 N; at 0.7 MPa expect 220 N and 185 N. The theoretical maximum for the bore is roughly 32 kgf at 1.0 MPa. Supply pressure runs 0.15-1.0 MPa (22-145 psi), proof pressure is 1.5 MPa (215 psi), and the speed range is 30-800 mm/s.
Yes - the magnet is standard on every MA-series piston, flanged or not, so CMSG, DMSG and EMSG switches snap onto the barrel for stroke-end or mid-stroke signalling with no special order.
