Airtac MAC Stainless Steel Mini Air Cylinder MAC63X80SUH
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X80SUH is a genuine double acting + cushion standard round-body mini air cylinder with a Ø63mm bore and 80mm 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 MAC63X80SUH
The MAC63X80SUH pairs a big 63 mm bore with a short 80 mm stroke, giving 1558 N of push at 0.5 MPa and 2181 N at 0.7 MPa in a round-body package barely longer than its own rod. Air works the piston in both directions, and a variable air cushion at each end lets you tune deceleration to the load instead of living with fixed rubber bumpers.
The stainless-steel barrel and hard-chrome-plated 16 mm rod laugh at condensation, coolants and outdoor weather - a genuine edge in washdown and marine-adjacent plants. A position magnet is built in as standard for CMSG / DMSG / EMSG switches. Working from the rating, count on about 935 N of practical push at 0.5 MPa; the 317.7 kgf theoretical maximum is a ceiling, not a working number.

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 MAC63X80SUH Is Used
Cutoff assist on FFS bagging machines
With 1558 N at 0.5 MPa it drives cutoff blades and hold-down shoes on form-fill-seal baggers; cushion tuning keeps the stroke quiet across 30-800 mm/s cycles.
Locking split cores on rotational molds
About 935 N of working force at 0.5 MPa clamps split cores on rotomolded tanks, and the stainless barrel tolerates mold-release mist that corrodes painted minis.
Swinging heavy weldment fixtures
1457 N of pull at 0.5 MPa retracts the pivot arm on rotating weld fixtures, so one cylinder handles the swing instead of adding a second.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X80SUH the Right Cylinder?
One ordering note first: the trailing H after the U flat-end code is not in the standard option list of this series, so confirm from datasheet before committing. On force, a 50 mm bore pushes 981 N at 0.5 MPa - pick it when the job needs under about 600 N of work, and stay at 63 mm for the 935 N class. The rod starts coasting the moment air is lost, so spec a rod lock or pilot check valve wherever a raised load must stay put. FA flange, LB foot or SDB pivot brackets adapt the flat-end body to fixed or pivoting frames, on a 0.15-1.0 MPa (22-145 psi) air supply.
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 MAC63X80SUH FAQ
Push 1558 N and pull 1457 N at 0.5 MPa; push 2181 N at 0.7 MPa; 317.7 kgf theoretical maximum at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-800 mm/s, port 1/4 in., rod 16 mm with an M14x1.5 male thread.
Paint chips and rust creeps toward the bore; the riveted stainless barrel of the MAC series keeps its sealing surfaces intact through washdown and damp storage, while the variable cushions at both ends dial out impact so the aluminium covers last longer.
