Airtac MAC Stainless Steel Mini Air Cylinder MAC63X450SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X450SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø63mm bore and 450mm 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 MAC63X450SCA
Few mini cylinders hold their accuracy across 450 mm of travel, yet the MAC63X450SCA does it with a stainless round barrel riveted to aluminium covers and a hard-chrome rod that shrugs off shop grime. Double acting with an adjustable air cushion at both ends, it carries 1557.9 N of push and 1457.4 N of pull at 0.5 MPa along the full stroke.
For deep-reach jobs the numbers translate directly: about 935 N of dependable working force at 0.5 MPa, or roughly 79 kg of vertical lift when a 2:1 margin is applied. The 450 mm stroke sits inside the 500 mm standard range for this bore, so no made-to-order tooling is needed. CA pivot mounting on the back cover suits swinging mechanisms, and the standard magnet works with CMSG / DMSG / EMSG switches along the whole barrel.

Where the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X450SCA Is Used
Deep drawer ejector
Pushes loaded 1200 mm sheet-metal drawers out of a cabinet rack - 935 N of working force overcomes drawer slide friction at full extension.
Kiln car pusher
Advances a small kiln car one station on a ceramics line, where the cushioned ends stop the car gently at each position.
Oven gate slide
Slides a baking-oven door across its full 450 mm opening, with the stainless barrel tolerating heat-zone humidity and flour dust.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X450SCA the Right Cylinder?
Bore 50 offers 981.3 N at 0.5 MPa if the load is lighter, but nothing in the MAC family exceeds the 63 mm bore, so this is the ceiling for push force. Long strokes amplify misalignment - guide the load externally and keep side force off the 16 mm rod, or rod bending will show up as seal wear within weeks. The CA pivot cover plus an SDB bracket keeps the cylinder aligned through its arc; FA flange and LB foot mounts are available for rigid frames.
If the gate or ejector must stay in position when air fails, fit a pilot check valve or rod lock, because a plain MAC releases its load as soon as pressure drops.
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 MAC63X450SCA FAQ
Push is 1557.9 N and pull 1457.4 N at 0.5 MPa; at 0.7 MPa the push reaches 2181.0 N and the pull 2040.3 N. Theoretical maximum at 1.0 MPa is 317.7 kgf. Ports are 1/4 inch, the rod thread is M14x1.5, and 450 mm is a standard stroke for the 63 mm bore.
Both ends carry a variable air cushion controlled by needle screws. On commissioning, back the screws fully off, run a few slow cycles, then close them gradually until end-of-stroke knock disappears. Running speed can sit anywhere from 30 to 800 mm/s while the cushion absorbs the load's momentum.
