Airtac MAC Stainless Steel Mini Air Cylinder MAC63X80SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X80SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø63mm 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 MAC63X80SCA
Swinging loads take the MAC63X80SCA: its CA back cover carries a pivot eye so the cylinder articulates with the linkage instead of fighting it. Behind the pivot sits a 63 mm bore producing 1557.9 N at 0.5 MPa and 2181.0 N at 0.7 MPa, double acting with a variable air cushion at either end.
The barrel is a rolled stainless tube with a hard-chrome carbon-steel rod, a combination that shrugs off washdown in food and outdoor service. A magnet is built into the piston as standard, so CMSG, DMSG or EMSG switches read position with no modifications. Derate for real work: aim near 935 N of continuous effort at 0.5 MPa, which is also enough to hoist roughly 79 kg vertically with a 2:1 margin.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1458 N |
| 0.7 MPa | 2182 N | 2041 N |
| Max (@1.0 MPa) | 318 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 MAC63X80SCA Is Used
Mixer lid lifter
Tilts a 70 kg stainless mixer lid open on a hinge; the CA pivot tracks the arc and the cushion lands the lid soft.
Pallet stopper arm
Drops a heavy stop arm in front of forklift traffic at a dock door; a magnet switch proves the arm is down.
Sluice gate actuator
Drives a waste-water sluice gate 80 mm against grit load; the chrome rod and stainless body handle humid pit air.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X80SCA the Right Cylinder?
A 50 mm MAC delivers 981.3 N at 0.5 MPa if the pivot load is lighter, while 63 mm is the strongest bore this series offers. The CA pivot cover can hang on a machine pin or pair with an SDB pivot bracket; FA flange and LB foot options exist for rigid fixings. On a centred valve or lost air the rod floats freely, so spec a pilot check valve where a gate must stay parked. 1/4" ports, M14x1.5 male rod thread, 16 mm rod.
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 MAC63X80SCA FAQ
0.5 MPa gives 1557.9 N push and 1457.4 N pull; 0.7 MPa gives 2181.0 N push and 2040.3 N pull; the 1.0 MPa theoretical ceiling is 317.7 kgf. Run it anywhere in 0.15-1.0 MPa (22-145 psi), proof tested to 1.5 MPa (215 psi).
It adds a pivot eye to the rear of the cylinder, so rod-side linkages can swing through an arc without side-loading the 16 mm chrome rod. Cushion needles at both ends stay adjustable - open them before the first stroke and close slowly to suit speeds from 30 to 800 mm/s.
