Airtac MAC Stainless Steel Mini Air Cylinder MAC16X400SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC16X400SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø16mm bore and 400mm stroke, M5×0.8 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 MAC16X400SCA
With a pivot CA back cover and a 400 mm stroke, this MAC takes a 6 mm chrome-plated rod through a riveted stainless barrel - a round-body build that tolerates damp and washdown far better than painted minis. Push force is 100.5 N at 0.5 MPa (140.7 N at 0.7 MPa) and the double-acting design cushions both ends with an adjustable air cushion.
The pivot capability of the CA cover lets the cylinder swing with a lever or linkage through the full 400 mm travel. Rated for 0.15-1.0 MPa (22-145 psi) and 30-800 mm/s, it carries a standard magnet for CMSG / DMSG / EMSG switches. For lift sums, 100.5 N at 0.5 MPa corresponds to roughly 10 kg vertically at rating - halve that for a 2:1 margin and it lifts about 5 kg.

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 (Ø16mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 101 N | 86 N |
| 0.7 MPa | 141 N | 121 N |
| Max (@1.0 MPa) | 21 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 MAC16X400SCA Is Used
Lid lift on a bakery tray filler
Pivots a light stainless guard lid open and closed over a 400 mm arc; about 5 kg of vertical lift capacity with a 2:1 margin covers most tray lids.
Lever-driven clamp on a solder jig
Works through a pivot lever to hold PCBs during solder inspection; the CA cover swings with the lever, so no extra clevis is needed.
Kick-off arm at a carton infeed
Swings misaligned cartons off a belt at the infeed; the adjustable cushion stops the arm softly at both ends of its sweep.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC16X400SCA the Right Cylinder?
The 20 mm MA bore offers 157.0 N at 0.5 MPa if this force class feels marginal; there is no smaller MA bore. A plain MAC will not hold position when air is lost - add a rod lock or pilot check valve where a raised load must stay put. Mount with an SDB pivot bracket or LB foot to match the CA cover, and keep the long 400 mm stroke side-load free so the 6 mm rod is not bent.
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 MAC16X400SCA FAQ
At 0.5 MPa supply the 16 mm bore gives 100.5 N push and 86.4 N pull; at 0.7 MPa these become 140.7 N push and 120.9 N pull, and the theoretical ceiling is 20.5 kgf at 1.0 MPa. The 400 mm stroke sits inside the 500 mm standard range, with 0.15-1.0 MPa (22-145 psi) working pressure and 30-800 mm/s speed.
Yes - every MAC ships with the piston magnet already installed, so CMSG, DMSG or EMSG reed switches mount on the stainless barrel without a special-order piston. That makes end-of-stroke or mid-stroke signalling a drop-on fit for the pivot CA cover arrangement.
