Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X80-20S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X80-20S is a genuine double acting, adjustable stroke + 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 MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X80-20S
Bench-fit once, trim on the machine later: this 63 mm AirTAC mini cylinder ships at 80 mm stroke with a 20 mm adjustable extend window, so the stop screw sets the exact end position after installation. Both ends carry a variable air cushion, and double-acting air produces 1557.9 N of push at 0.5 MPa (1457.4 N on the return), climbing to 2181.0 N at 0.7 MPa from a 0.15-1.0 MPa (22-145 psi) supply.
Converted for lifting, the 0.5 MPa push equals about 158 kg vertical, and a 2:1 factor still leaves close to 79 kg of usable payload. The riveted stainless barrel takes washdown that would corrode painted minis, the 16 mm rod is hard-chrome plated to 20 um, and the standard-fit magnet means CMSG, DMSG or EMSG switches bolt straight on.

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 MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X80-20S Is Used
Platen drives on case erectors
Set platen depth inside the 20 mm window for different case heights; 2181.0 N push at 0.7 MPa squares tall corrugated cases without slamming the frame.
Lift-and-locate plates under assembly presses
About 79 kg vertical lift at a 2:1 margin raises heavy fixture plates between press cycles, with end cushions protecting the locate pins.
Position-checked reject gates on filling lines
The standard magnet plus a CMSG switch confirms every gate position, while the stainless body copes with sticky, wet product zones.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X80-20S the Right Cylinder?
Size check: the 50 mm bore delivers 981.3 N push at 0.5 MPa, while this 63 mm bore adds roughly 59% more force - a real difference on stiff clamps and heavy gates. As the largest MA bore there is no step up within the series; pair two cylinders when more thrust is needed. FA flange and LB foot mounts are supported with I and Y rod knuckles for linkages, and 1/4" ports keep cushion fill quick. Remember the adjuster is an extend-side end stop, not a brake - support any suspended load separately if air fails.
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 MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X80-20S FAQ
Push 1557.9 N and pull 1457.4 N at 0.5 MPa; push 2181.0 N and pull 2040.3 N at 0.7 MPa; theoretical maximum 317.7 kgf at 1.0 MPa. Stroke 80 mm with a 20 mm adjustable extend window, variable air cushion at both ends, 1/4" ports, 16 mm hard-chrome rod, operating pressure 0.15-1.0 MPa (22-145 psi) and speed 30-800 mm/s.
Yes. The barrel is stainless steel with riveted aluminium covers, and the 16 mm carbon-steel rod carries a 20 um hard-chrome plate, so splash, humidity and routine washdown corrode it far more slowly than a painted mini cylinder.
