Airtac MAC Stainless Steel Mini Air Cylinder MAC50X80SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X80SCA 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 MAC50X80SCA
A 50 mm bore gives the MAC50X80SCA a push of 981 N at 0.5 MPa, enough muscle for medium clamps, press-assist heads and slides in a compact round body. The cylinder is double acting, so air both extends the 16 mm rod and returns it, and variable air cushions at each end absorb the last of the stroke - open the needle screws on first start-up, then dial them in gradually to run the full 30-800 mm/s speed range without cover hammer. At 0.7 MPa output climbs to 1374 N.
Because the barrel is stainless steel and the rod is hard-chrome plated carbon steel, this mini cylinder tolerates washdown, condensation and outdoor exposure that rust painted units within months. The CA pivot back cover lets the whole body swing on a pin, handy for lever linkages and swing clamps, while the factory-fitted magnet accepts CMSG, DMSG or EMSG switches with no special piston needed. When budgeting real work, plan on about 589 N at 0.5 MPa - roughly 60 percent of the rating - and keep the rest as headroom.

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 MAC50X80SCA Is Used
Brewery bottle-line gate
Swinging a divert gate across a bottling conveyor between two lanes; the daily caustic hose-down is exactly where the stainless barrel outlives painted minis, and 981 N at 0.5 MPa snaps the gate home fast.
CNC swing clamp
Driving a swing clamp on a fixture machining aluminium brackets - the CA rear pin bolts straight to the linkage arm and the twin cushions stop the clamp jaw hammering at the end of its 80 mm travel.
Carton lane pusher
Pushing stacked 12-pack cartons off a picking lane into a shrink-wrap infeed; working on a 589 N practical budget leaves ample margin for a 5 kg carton stack and a sticky lane.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X80SCA the Right Cylinder?
Size both ways before committing: the MAC32X80 offers 402 N at 0.5 MPa for lighter duties, while the MAC63X80 reaches 1558 N if loads grow. One thing this design will not do is hold position - when air pressure drops or the valve centres, the rod simply drifts, so a rod lock or pilot check valve is needed for suspended loads. Air ports are 1/4" and the rod thread is M14x1.5; running range is 0.15-1.0 MPa (22-145 psi) with proof at 1.5 MPa (215 psi). The CA pivot pairs naturally with swing arms, and FA flange, LB foot or SDB brackets cover fixed frames; the 80 mm stroke sits well inside the 500 mm standard range for this bore.
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 MAC50X80SCA FAQ
At 0.5 MPa it pushes with 981 N and pulls with 881 N. Raise supply to 0.7 MPa and those figures become 1374 N push and 1233 N pull. The theoretical maximum at 1.0 MPa is 200 kgf of thrust.
No. Every MAC50X80SCA carries a built-in piston magnet as standard, so CMSG, DMSG or EMSG switches clip onto the stainless barrel and read end-of-stroke positions straight away.
