Airtac MAC Stainless Steel Mini Air Cylinder MAC63X450SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X450SU 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 MAC63X450SU
Flat, flush and simple - the MAC63X450SU pairs a 450 mm stroke and bore 63 muscle with a U flat-end back cover that bolts square to machine plates. Double acting with a variable air cushion at each end, it develops 1557.9 N of push and 1457.4 N of pull at 0.5 MPa.
Washdown and damp shops are where the riveted stainless barrel earns its keep; the 20 um hard-chrome carbon-steel rod resists scoring and rust far better than painted aluminium minis. Budget for about 935 N of real working push at 0.5 MPa - enough to raise a 79 kg load vertically with a 2:1 margin - and dial end-of-stroke shock out with the cushion needle screws.

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 MAC63X450SU Is Used
Bolt-on ejector on a stamping line
Scrap slug ejection under a heavy press needs a flush flat mount; the U cover bolts straight to the die shoe and 1557.9 N at 0.5 MPa clears stubborn offcuts on the 450 mm return stroke.
Pallet-stopper gate in a cold store
Damp cold-store air kills painted cylinders; the stainless MAC barrel raises a 75 kg pallet stop gate through 450 mm while keeping a 2:1 margin on its 79 kg vertical lift figure.
Concrete compaction ram in a materials lab
A test lab consolidates fresh concrete specimens in 450 mm lifts; the flat-end cover clamps to the test frame and the adjustable cushion settles the ram gently at the bottom of each stroke.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X450SU the Right Cylinder?
Step down to bore 50 (981.3 N push at 0.5 MPa) when the load is lighter; bore 63 is the strongest MAC available, so nothing larger exists in this series. Because air on both sides is the only thing positioning the piston, a centred valve lets the rod drift under its own load - fit a rod lock or pilot check valve where the 450 mm stroke must hold position. The flat-end U cover sits flush against brackets, the magnet suits CMSG, DMSG and EMSG switches as standard, and at this length a guided load is essential to protect the 16 mm rod from side forces.
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 MAC63X450SU FAQ
Push is 1557.9 N at 0.5 MPa and 2181.0 N at 0.7 MPa; pull is 1457.4 N at 0.5 MPa and 2040.3 N at 0.7 MPa. Theoretical maximum is 317.7 kgf at 1.0 MPa. Supply is 0.15-1.0 MPa (22-145 psi) of 40 um filtered air, 1/4" ports, M14x1.5 rod thread, speed 30-800 mm/s.
The flat-end U cover presents a clean square face for plate or bracket bolting without adapters, while SDB pivot or FA flange mounts handle other frames. The magnet is installed as standard on every MA-series piston, so CMSG, DMSG and EMSG switches mount anywhere along the tube for end-of-stroke or mid-stroke signals.
