Airtac MAC Stainless Steel Mini Air Cylinder MAC63X550SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X550SU 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 MAC63X550SU
With a 63 mm bore pushing 1558 N at 0.5 MPa (22-145 psi operating band), the MAC63X550SU sits at the top of AirTAC's cushioned round mini family. It is double acting - compressed air drives the rod out and pulls it back - and a variable air cushion at each end lets you tune away end-of-stroke shock, so faster cycles or heavier loads stop without hammering the covers. Supply air filtered to 40 um, speed 30-800 mm/s, proof pressure 1.5 MPa (215 psi).
The riveted stainless barrel and hard-chrome plated carbon-steel rod (20 um) laugh at washdown and humid plant air where painted minis start to pit. For real sizing, keep the working force near 935 N at 0.5 MPa - in lifting terms about 79 kg vertical with a 2:1 margin. The U flat-end back cover mounts to fixed plates without adapters, and the built-in magnet (fitted as standard) accepts CMSG / DMSG / EMSG switches for position signals.

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 MAC63X550SU Is Used
Pallet stop gate lift
Raising a 60 kg roller-stop gate at the discharge end of a pallet conveyor. The 550 mm stroke clears a full gate height and the U flat-end cover bolts straight to the machine frame.
Tray squaring in washdown
Squaring shrink-wrapped tray stacks on a dairy-line infeed, where the stainless barrel and chrome rod outlast painted minis under daily hose-down. Around 935 N of working push squares even overfilled stacks.
Press guard slide
Driving a 550 mm sliding guard panel on a press brake. The variable cushion at both ends quiets the panel each cycle, and a CMSG switch confirms closed position to the control.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X550SU the Right Cylinder?
For lighter duty, the 50 mm bore of this family gives 981 N at 0.5 MPa; at 63 mm you are at the top of the range with 1558 N. The 550 mm stroke passes the 500 mm standard ceiling, so AirTAC builds it to order. Keep external guides on the load so the 16 mm rod sees thrust only, and match the U flat-end cover with FA flange, LB foot or SDB pivot hardware as the frame needs. Once air drops the rod moves freely - a rod lock or pilot check valve keeps a raised gate where you left it.
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 MAC63X550SU FAQ
At 0.5 MPa the 63 mm piston pushes 1557.9 N and pulls 1457.4 N. Raise supply to 0.7 MPa and those become 2181.0 N push / 2040.3 N pull. The theoretical maximum at 1.0 MPa is 317.7 kgf. Speed range is 30-800 mm/s with a variable cushion at both ends.
Back both cushion needle screws fully out before the first stroke, then close them gradually until end-of-stroke impact disappears at your cycle speed. The cushion is variable, not fixed, so you can retune it anywhere in the 30-800 mm/s band. It absorbs motion but does not lock the piston - air loss still lets the rod move.
