Airtac MAC Stainless Steel Mini Air Cylinder MAC63X50SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X50SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø63mm bore and 50mm 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 MAC63X50SU
MAC63X50SU tops the MAC range with a 63 mm bore on a short 50 mm stroke, double acting so air drives the rod both out and back, with a variable air cushion at each end. At 0.5 MPa it pushes 1557.9 N and pulls 1457.4 N, and at 0.7 MPa push reaches 2181.0 N; the theoretical ceiling is 317.7 kgf. The U flat-end back cover presents a machined flat face, so fixed brackets bolt straight on without adapter plates.
Its stainless round barrel and 20 um hard-chrome plated rod resist washdown and humid shop air far better than painted minis, a genuine edge in food and outdoor cells. Run it on 0.15-1.0 MPa (22-145 psi) filtered air at 30-800 mm/s. In practice budget about 935 N for real work at 0.5 MPa, and the bore will lift roughly 79 kg vertically with a 2:1 reserve. The piston magnet is fitted as standard, so CMSG, DMSG or EMSG switches attach with no 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 (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 MAC63X50SU Is Used
Weld fixture clamping
Clamps sheet-metal stampings on an automotive body jig; the flat-end cover bolts directly to the fixture riser and 1557.9 N holds the panel through spot welding.
Carton ejection
Pushes filled 12-pack cartons across a beverage conveyor transfer; the cushion at both ends stops the platen from slamming over its 50 mm travel.
Bushing press
Presses bronze bushings into pump housings on a compact bench station, working off the roughly 935 N of practical force available at 0.5 MPa.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X50SU the Right Cylinder?
At 1557.9 N push on 0.5 MPa, this bore is the top of the MAC range, so downsize to a 50 mm bore (981.3 N push) if your load is lighter. Note the cylinder does not hold load when air is lost - the piston drifts - so fit a rod lock or pilot check valve for suspended loads. Mount with FA flange, LB foot or SDB pivot bracket; add an I or Y rod knuckle for off-axis links. The 50 mm stroke keeps side-load and rod bending negligible at the listed speeds.
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 MAC63X50SU FAQ
At 0.5 MPa the 63 mm bore pushes 1557.9 N and pulls 1457.4 N; at 0.7 MPa push rises to 2181.0 N with pull at 2040.3 N; theoretical maximum is 317.7 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), air filtered to 40 um, rod speed 30-800 mm/s, 1/4 in ports and M14x1.5 rod thread.
No. Every MAC cylinder ships with the magnet already fitted in the piston as standard equipment, so CMSG, DMSG and EMSG reed or Hall-effect switches mount on the barrel for end-of-stroke or mid-stroke position signals without any special-order piston.
