Airtac MAC Stainless Steel Mini Air Cylinder MAC20X220SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X220SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 220mm 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 MAC20X220SCA
A double-acting round-body mini cylinder with a variable air cushion at both ends, the MAC20X220SCA drives its 8 mm rod with 157 N at 0.5 MPa and 219.8 N at 0.7 MPa over a 220 mm stroke. The CA pivot back cover accepts a clevis pin directly, so swinging link arms need no extra bracket. Compressed air both extends and retracts the piston, and the cushion needles absorb end-of-stroke shock so you can run the full 30-800 mm/s speed range without hammering the covers.
Construction is a riveted stainless-steel barrel with a hard-chrome plated carbon-steel rod, an edge over painted minis in damp washdown corners. Every unit ships with the magnet built in as standard, so CMSG, DMSG or EMSG switches clip on with no special-order piston. Plan on roughly 94 N of usable push, six tenths of the 157 N rating, which lifts about 8 kg vertically with a 2:1 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 MAC20X220SCA Is Used
Bottle push-off arm
Swings a CA-pivoted pusher arm that nudges 1 L bottles off a beverage conveyor, working within the 8 kg equivalent vertical load the 157 N push supports.
Carton flap tuck
The 220 mm travel tucks the final flap on a snack carton sealer; the 157 N push at 0.5 MPa clears glue-set resistance without oversizing the bore.
Lab slide gate
Opens a stainless slide gate on a mixing station, where washdown spray would rust a painted mini cylinder but not this stainless barrel and chrome rod.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X220SCA the Right Cylinder?
Size down to a MAC16 if 100.5 N at 0.5 MPa is enough, or step up to a MAC25 for 245.3 N. A plain MAC drifts when air is lost or the valve centres because it has no hold, so fit a rod lock or pilot check valve if the load must stay put. The 220 mm stroke on an 8 mm rod means side loads should be guided externally; add FA flange or LB foot mounts and an I or Y rod knuckle to keep bending off the rod.
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 MAC20X220SCA FAQ
At 0.5 MPa it pushes 157 N and pulls 131.9 N; at 0.7 MPa that rises to 219.8 N push and 184.7 N pull. Theoretical maximum is 32.0 kgf at 1.0 MPa. The 1/8 inch port feeds both chambers, and the variable cushion at each end lets you tune deceleration across the whole 220 mm stroke.
Back both cushion needle screws fully open before the first stroke, then close them gradually until the rod stops smoothly. This protects the aluminium covers and lets you raise cycle speed toward 800 mm/s. The standard built-in magnet also accepts CMSG, DMSG and EMSG switches for end-of-stroke signalling.
