Airtac MAC Stainless Steel Mini Air Cylinder MAC63X800SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X800SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø63mm bore and 800mm 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 MAC63X800SU
A round-body mini cylinder built on a stainless barrel, the MAC63X800SU runs double acting with a variable air cushion at both ends, so end-of-stroke shock can be tuned out on long, fast moves. At 0.5 MPa it pushes 1557.9 N and pulls 1457.4 N, climbing to 2181.0 N at 0.7 MPa - muscle enough for heavy clamp-and-push work across a full 800 mm of travel.
The hard-chrome plated 16 mm carbon-steel rod rides inside a rolled, riveted aluminium cover set on a stainless tube, so the body stands up to washdown and damp plant air where painted minis corrode. On a 2:1 margin this bore lifts about 79 kg vertically; the built-in magnet (standard, not a paid option) drops CMSG / DMSG / EMSG switches straight on, and the U flat-end back cover bolts directly to a fixed plate.

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 MAC63X800SU Is Used
Pallet gate lifting on a warehouse line
A vertical gate or lift mast that raises around 79 kg with margin, stroking 800 mm between floor level and conveyor height, with the cushion easing the gate onto its stops.
Scrap ejector under a stamping press
With 2181.0 N available at 0.7 MPa, the cylinder shoves heavy offcuts down a chute at the press pit, and the stainless barrel shrugs off coolant mist and swarf spray.
Heavy carton pusher on a palletising conveyor
The U flat-end back cover mounts flat to the conveyor frame, while 1557.9 N of push at 0.5 MPa moves full shrink-wrapped bundles sideways at speed without cover hammering.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X800SU the Right Cylinder?
63 mm is the top of the MAC family: the next bore down, 50 mm, delivers 981 N at 0.5 MPa, so choose this size only when a load genuinely needs the extra 577 N. Supply air at 0.15-1.0 MPa (22-145 psi), run 30-800 mm/s, and use the needle screws to soften both ends of the stroke.
The 800 mm stroke exceeds the 500 mm standard limit for this bore, so the unit is made to order - confirm the exact dimension before ordering. On a stroke this long, guide the load externally and keep side load off the rod to prevent bending. A plain MAC will drift once air is removed, so add a rod lock or pilot check valve wherever the load must stay parked; LB foot or FA flange mounts plus I and Y rod knuckles round out the assembly, and G or NPT ports can be ordered in place of the standard PT.
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 MAC63X800SU FAQ
At 0.5 MPa it pushes 1557.9 N and pulls 1457.4 N; at 0.7 MPa, 2181.0 N push and 2040.3 N pull; the theoretical maximum is 317.7 kgf at 1.0 MPa. The bore is 63 mm with a 16 mm rod, 1/4" ports, M14x1.5 rod thread, working pressure 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed range 30-800 mm/s and operation from -20 to +70 C.
Standard strokes for the 63 mm bore run up to 500 mm, so the 800 mm version is built to order - confirm the exact dimension from the datasheet before ordering. Sensors are no problem: the magnet comes built in as standard on every MAC cylinder, so CMSG, DMSG or EMSG switches mount directly onto the barrel body with no special piston required.
