Airtac MAC Stainless Steel Mini Air Cylinder MAC63X550SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X550SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø63mm bore and 550mm 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 MAC63X550SCA
Long travel, big bore: the MAC63X550SCA stretches the standard MAC format to a 550 mm stroke - 50 mm past the usual 500 mm limit for this bore, so it is built to order - while keeping the 1558 N push at 0.5 MPa a 63 mm piston generates. It is double acting with variable air cushions at both ends, hung on a CA pivot back cover for linkage work. In round numbers that is roughly 935 N of trustworthy working force, or about 159 kg lifted vertically at 0.5 MPa - call it 79 kg once you keep a 2:1 margin.
Over 550 mm, rod alignment matters, and the stainless barrel with its 16 mm hard-chrome rod rewards careful mounting; a stainless round body also tolerates outdoor rain and food-plant hose-down far better than a painted mini. The magnet comes fitted as standard for CMSG / DMSG / EMSG switching along the full travel. Ports are 1/4", the rod ends in M14x1.5 thread, and cushion tuning keeps 30-800 mm/s travel smooth at each end of the long stroke.

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 MAC63X550SCA Is Used
Cross-belt pallet pushers
Clears a full pallet lane on 550 mm of travel; conveyor stops and diverters stay smooth on the end cushions.
Loading-bay door latches
Drives the latch bar on warehouse roller doors; the CA pivot follows the door arm through its arc.
Sluice gate actuation
Cycles wastewater sluice gates in the open air; stainless barrel and chrome rod stand up to weather year after year.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X550SCA the Right Cylinder?
Nothing else in the MA family reaches this span at this force: below it sits a MAC50X550 at 981 N push at 0.5 MPa, and beyond 63 mm you change series altogether - this is the biggest bore at 317.7 kgf theoretical. Run it on 0.15-1.0 MPa (22-145 psi) with 40 um filtered air. On strokes this long, guard the rod against side load and add external guidance for anything off-axis, or rod bending will show up long before the 1558 N rating does. A plain MAC cannot hold a load against gravity when air drops - fit a rod lock or pilot check valve - and the CA pivot can be swapped in the code for CM or U if a fixed back mount suits the machine better.
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 MAC63X550SCA FAQ
A 550 mm stroke, made to order because standard MAC strokes stop at 500 mm for this bore. Output: 1558 N push and 1457 N pull at 0.5 MPa, 2181 N push and 2040 N pull at 0.7 MPa, with a theoretical maximum of 317.7 kgf at 1.0 MPa.
Yes - the same riveted stainless barrel and 20 um hard-chrome rod run the full 550 mm, and the standard magnet carries CMSG / DMSG / EMSG switches along the whole stroke. Just keep the rod guided against side loads to protect the seals over the long travel.
