Airtac MAC Stainless Steel Mini Air Cylinder MAC63X80SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X80SCM 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 MAC63X80SCM
With a 63 mm bore and 80 mm stroke, the MAC63X80SCM sits at the top of the MAC cushioned mini range, pushing 1558 N at 0.5 MPa and about 2181 N at 0.7 MPa while keeping a compact round-body footprint. Air drives the piston both ways, and a variable air cushion at each end soaks up end-of-stroke shock so heavier payloads can cycle faster without hammering the covers.
The riveted body pairs a stainless-steel barrel with a 16 mm hard-chrome-plated rod, so it shrugs off mild corrosion and washdown in damp or food-plant spots that would pit painted minis. Every cylinder ships with a built-in magnet, meaning CMSG / DMSG / EMSG switches clip on without a special-order piston. In practice, treat the 1558 N push rating as roughly 935 N of real work at 0.5 MPa - plan jig and payload weights around that figure and the cylinder keeps margin for pressure drop.

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 MAC63X80SCM Is Used
Pallet diverting on conveyor lines
1558 N at 0.5 MPa swings heavy stopper arms and diverters; the adjustable cushion drops the arm into position without a bang at every cycle.
Washdown bin lifting in food plants
With about 79 kg of vertical lift at a 2:1 margin, it raises loaded ingredient bins on washdown lines where painted mini cylinders corrode.
Bench-top marking and staking presses
The 2181 N push at 0.7 MPa drives stamp heads on aluminium extrusions; the CM round-end pivot links straight to a toggle lever.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X80SCM the Right Cylinder?
Bore 63 is the largest in this series: it delivers 1558 N at 0.5 MPa against 981 N from a 50 mm bore, so step down to a 50 only if your work force sits under about 600 N. It runs on filtered air at 0.15-1.0 MPa (22-145 psi). Like any double-acting cylinder, the rod drifts when air is removed or the valve centres - add a rod lock or pilot check valve if the load must stay put. The CM round-end back cover takes a pivot pin directly, and FA flange, LB foot or SDB pivot brackets bolt on for fixed frames. At 80 mm the stroke is short, so side load on the 16 mm rod stays minimal.
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 MAC63X80SCM FAQ
At 0.5 MPa it pushes 1558 N and pulls 1457 N; at 0.7 MPa the push rises to 2181 N. The theoretical maximum is 317.7 kgf at 1.0 MPa. The port is 1/4 in., the rod is 16 mm with an M14x1.5 male thread, and strokes up to 500 mm are standard, so 80 mm sits well inside the range.
It accepts a pivot pin directly, so swinging or linkage mounts need no extra bracket. On first run, back the cushion needle screws fully off, then open them gradually to tune end-of-stroke deceleration; the working speed range is 30-800 mm/s.
