Airtac MAC Stainless Steel Mini Air Cylinder MAC63X500SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X500SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø63mm bore and 500mm 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 MAC63X500SU
When a heavy thrust stroke must bolt flush against a machine frame, the U flat-end back cover gives a clean fixed mount without adapter plates. This 63 mm bore MAC generates 1557.9 N of push and 1457.4 N of pull at 0.5 MPa, climbing to 2181.0 N and 2040.3 N at 0.7 MPa, with a theoretical ceiling of 317.7 kgf at 1.0 MPa. Size the real job around 935 N or less so seal friction and pressure dips never stall the stroke mid-way.
Air cushions at both ends are needle-adjustable, so a 500 mm travel run at up to 800 mm/s can be eased to a stop instead of hammering the covers, with the working window set by 0.15-1.0 MPa (22-145 psi) supply. The rolled stainless-steel barrel and 20 um hard-chrome rod take washdown and humid air that would corrode painted minis, and the magnet built in as standard accepts CMSG / DMSG / EMSG switches with no special piston order. At 500 mm this is the maximum standard stroke for the bore - a catalogue item, not a custom build.

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 MAC63X500SU Is Used
Grain silo vent hatch
Raising a 70 kg vent hatch on a farm silo: the 79 kg practical vertical lift figure (159 kg theoretical, halved for a 2:1 margin) covers it at 0.5 MPa.
Baler eject plate
Pushing compacted cardboard bales out of a recycling baler chamber, where 2181.0 N at 0.7 MPa overcomes sticking and the cushion softens the eject.
Extrusion clamping fixture
Holding long aluminium profiles against a machining stop; the flat-end cover bolts straight to the fixture wall and 1/4" ports feed both chambers.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X500SU the Right Cylinder?
Step down to the 40 mm bore, which pushes 628.3 N at 0.5 MPa, if the load is lighter; nothing above 63 mm exists in the MAC family, so this is the strongest standard mini in the series. Do not count on it to hold position when air is removed - the piston coasts and drifts, so fit a rod lock or pilot check valve wherever a load has to wait under power-off. FA flange, LB foot or SDB pivot brackets all bolt to the U flat-end body, 1/4" ports feed both chambers, and the standard magnet gives drop-on switch mounting if mid-travel sensing is needed. With a long 500 mm stroke, guide the load externally so the 16 mm rod never sees side bending.
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 MAC63X500SU FAQ
At 0.5 MPa expect 1557.9 N push and 1457.4 N pull; at 0.7 MPa, 2181.0 N push and 2040.3 N pull; the theoretical ceiling is 317.7 kgf at 1.0 MPa. Supply is 0.15-1.0 MPa (22-145 psi), speed range 30-800 mm/s, proof pressure 1.5 MPa (215 psi), with 1/4" ports and an M14x1.5 male rod thread.
The barrel is stainless steel with rolled-in covers and the 16 mm rod carries a 20 um hard-chrome plating, so splash, humidity and outdoor weather that rust painted minis leave this one serviceable. It is a riveted round-body design - neither a tie-rod nor an extruded profile cylinder - and the standard magnet allows CMSG / DMSG / EMSG switch fitting at any point along the stroke.
