Airtac MAC Stainless Steel Mini Air Cylinder MAC16X250SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC16X250SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø16mm bore and 250mm 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 MAC16X250SU
A 250 mm stroke on the 16 mm bore MAC puts 100.5 N of push and 86.4 N of pull at 0.5 MPa behind a long, light sweep, working across a 0.15-1.0 MPa (22-145 psi) supply range. The body is a riveted stainless round barrel with rolled-on aluminium covers and a 20 um hard-chrome plated rod, so it shrugs off washdown and damp plant air where painted minis start to pit. Double-acting with a variable air cushion at each end, it covers light actuation duties at 30-800 mm/s.
Plan the work around roughly 60 N of usable push at 0.5 MPa instead of the full 100.5 N rating and you leave margin for friction and seal wear over the cylinder's life. The flat-end U back cover on this version bolts straight to a fixed plate without adapter blocks, and the magnet is fitted as standard, so CMSG / DMSG / EMSG switches clamp on the day the cylinder arrives. Back the cushion needle screws fully off before the first run, then open them gradually to tune the stop.

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 MAC16X250SU Is Used
Blister tray reject arm
A pharmaceutical packaging line uses the 250 mm sweep to push faulty blister trays sideways off a conveyor - 100.5 N is ample for a tray weighing a few hundred grams.
Analytical sampler lift
In a benchtop analytical instrument, the rod raises a 5 kg sample carousel, the weight it can lift vertically with a 2:1 margin on the 0.5 MPa push rating.
Enclosure dust shield slide
A CNC enclosure shield slides open over 250 mm; the dual cushions land the light panel softly at each end of travel instead of hammering the covers.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC16X250SU the Right Cylinder?
Bore 16 is the smallest in the family; if 100.5 N falls short, step up to the 20 mm bore at 157 N or the 25 mm bore at 245.3 N of push, both at 0.5 MPa. With 250 mm of travel, keep side loads off the 6 mm rod - guide the load externally or the rod will bend long before the barrel shows wear. Like any plain double-acting cylinder, the rod settles wherever pressure leaves it when air is cut, so add a pilot check valve if the slide must stay parked.
Pair the U back cover with an FA flange or LB foot for a fixed base, or choose the CA pivot cover for a swing link. Every piston carries the built-in magnet, so end-position sensing needs no special order.
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 MAC16X250SU FAQ
At 0.5 MPa it pushes 100.5 N and pulls 86.4 N; at 0.7 MPa the figures rise to 140.7 N and 120.9 N. The theoretical maximum at 1.0 MPa is 20.5 kgf. The 16 mm bore breathes through M5x0.8 ports, and the 6 mm rod carries an M6x1.0 male thread.
Both ends carry a variable air cushion. Back the needle screws fully off before the first run, then open them gradually until end-of-stroke impact disappears. Speed range is 30-800 mm/s, and the cushion only softens the final travel - it is not a brake that holds the rod.
