Airtac MAC Stainless Steel Mini Air Cylinder MAC16X40SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC16X40SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø16mm bore and 40mm 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 MAC16X40SU
The U flat-end back cover on the MAC16X40SU gives designers a clean fixed mounting face, backed by 100.5 N of push and 86.4 N of pull at 0.5 MPa. Double-acting air power moves the 6 mm rod both ways, and the variable cushion can be opened or closed at either end to suit the cycle. It operates from 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s.
Where painted minis flake and seize in damp corners, this one keeps a stainless barrel and a 20 um hard-chrome rod working - a genuine advantage near washdown tables or outdoor conveyors. Sensing needs no ordering tricks either: the magnet comes standard, ready for CMSG, DMSG or EMSG switches. Rating-wise, the 100.5 N push corresponds to a theoretical vertical lift of about 10 kg; halve that for a 2:1 margin and you can comfortably raise a 5 kg assembly jig component.

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 MAC16X40SU Is Used
Optics lens holder clamp
Clamps delicate lens carriers in an alignment jig; 100.5 N is gentle enough with a pressure regulator, and the flat U end bolts flush to the jig plate.
Dispensing depth stop
Sets needle height on a small adhesive dispenser; the cushion absorbs the down-stop, and an EMSG switch verifies the seated position each cycle.
Hopper sorting flap
Routes tiny fasteners between two chutes under a parts hopper; the stainless barrel handles dusty, slightly oily conditions that would rust painted minis.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC16X40SU the Right Cylinder?
Nothing sits below the 16 mm bore in this series, so treat it as your lightest option and move to 20 mm (157.0 N at 0.5 MPa) when loads grow. If the load must stay extended through a valve-off state, note that the rod will drift - a rod lock or pilot check valve is the fix. The U end covers plain face mounting, while FA flange, LB foot and SDB pivot brackets extend the options; the magnet is factory-fitted, not an add-on.
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 MAC16X40SU FAQ
Yes: push is 100.5 N and pull 86.4 N at 0.5 MPa; at 0.7 MPa it is 140.7 N push and 120.9 N pull; the theoretical ceiling is 20.5 kgf at 1.0 MPa. The air connection is M5x0.8, rod thread M6x1.0, rod 6 mm. Operating window is 0.15-1.0 MPa (22-145 psi), 30-800 mm/s, with a 40 mm stroke on this model.
In damp, food-adjacent or outdoor settings, definitely. The rolled stainless tube with a hard-chrome plated rod resists the rust and flaking that ruin painted or plain aluminium mini cylinders, keeping the low-friction bore seal intact for longer - and because the magnet is standard, sensor retrofits later need only a CMSG, DMSG or EMSG switch.
