Airtac MAC Stainless Steel Mini Air Cylinder MAC50X80SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X80SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 80mm stroke, 1/4" 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 MAC50X80SU
The MAC50X80SU finishes the barrel with a U flat-end back cover, giving a clean fixed mounting face while the 50 mm bore delivers 981 N at 0.5 MPa. Air pushes the rod out and pulls it back - double acting throughout - and twin adjustable air cushions trim end-of-stroke shock, a real benefit once cycle speeds climb within the 30-800 mm/s band.
Washdown lines and humid plants are where the stainless barrel plus hard-chrome 16 mm rod earn their keep, outlasting painted housings that bubble and seize. In lift terms the 981 N push equates to roughly 100 kgf, so derating to half leaves a comfortable 50 kg vertical lifting capability per unit. A magnet ships inside every MAC piston as standard, meaning CMSG, DMSG or EMSG reed switches mount on the tube for position feedback without ordering a special piston.

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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 881 N |
| 0.7 MPa | 1374 N | 1234 N |
| Max (@1.0 MPa) | 200 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 MAC50X80SU Is Used
Assembly-slide end stop
Serving as an adjustable end stop on the linear slide of an electronics assembly machine; the flat U rear cover bolts flush to the machine plate and the cushion absorbs pallet impact.
Roller-bed tote brake
Pressing a friction pad onto a gravity roller conveyor at a distribution hub to arrest fast-rolling tote bins before a manual pick station.
Fence-machine wire drag
Applying light drag to a wire spool payoff on a fencing machine; stock stored outdoors makes the stainless barrel and chrome rod a corrosion-resistant pairing.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X80SU the Right Cylinder?
Compare the MAC32X80, good for 402 N at 0.5 MPa, before settling on this bore; heavier work belongs on the MAC63X80 at 1558 N. Drop the air or park the valve mid-travel and the rod will coast - plan a rod lock or pilot check valve wherever a load must stay put. The U flat-end cover gives a stable fixed base, complemented by FA flange, LB foot and SDB pivot mounts, and I or Y knuckles on the M14x1.5 rod thread soak up slight misalignment. Pressure span is 0.15-1.0 MPa (22-145 psi) and ports are 1/4".
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 MAC50X80SU FAQ
On 0.5 MPa air it delivers 981 N forward and 881 N back. Supply 0.7 MPa and output rises to 1374 N forward, 1233 N back. The theoretical ceiling at 1.0 MPa is 200 kgf.
The flat U back cover bolts directly to machine frames, and the series adds FA flange, LB foot and SDB pivot brackets plus I and Y rod knuckles for alignment. The magnet fitted as standard also accepts CMSG, DMSG and EMSG switches, so position feedback needs no extra hardware.
