Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X50-30S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X50-30S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø63mm bore and 50mm 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 MACJ63X50-30S
Few mini cylinders move real tonnage; this 63 mm MACJ does. It clamps with 1557.9 N at 0.5 MPa, and its 30 mm adjustable window lets one body serve several fixture heights. Double-acting with a variable air cushion at both ends, it also slows gently into the covers when you push the speed toward 800 mm/s.
The math for lift jobs: 1557.9 N is about 159 kgf, so with a 2:1 safety margin the rod raises roughly 79 kg vertically. Build quality backs the number - a stainless round barrel rolled onto aluminium covers, a 20 um hard-chrome rod that resists scoring, and grease-retaining heterogeneous piston seals. Magnet included as standard for CMSG, DMSG and EMSG sensing.

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 MACJ63X50-30S Is Used
Weldment hold-down
Clamping steel weldments into a welding jig, where about 935 N of usable clamp force at 0.5 MPa resists weld shrinkage pull.
Lid press on filling line
Pressing snap lids onto 20 L pails after filling; the stainless barrel survives daily washdown of the filler deck.
Press-fit dowels
Seating dowel pins and small bearings in machine assembly, with the cushion preventing the pin from bouncing back out.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X50-30S the Right Cylinder?
For lighter clamps the 50 mm bore delivers 981.3 N push / 880.8 N pull at 0.5 MPa and costs less to run; nothing in the MA range out-pulls this 63 mm bore. Remember the 30 mm adjuster shortens the extend stroke only and is not a brake - an unsupported load will still drift if air is lost.
Choose FA flange for face mounting, LB foot for base work, and I or Y knuckles where the load pivots. The 50 mm stroke sits far under the 500 mm maximum for this bore, so rod buckling is not a concern across the 30-800 mm/s speed band.
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 MACJ63X50-30S FAQ
At 0.5 MPa expect 1557.9 N push and 1457.4 N pull; at 0.7 MPa, 2181.0 N push and 2040.3 N pull; the theoretical peak at 1.0 MPa is 317.7 kgf. Speed range is 30-800 mm/s with a variable cushion at each end.
The barrel is stainless steel with aluminium covers rolled on for a sealed, rigid body that shrugs off washdown, humidity and outdoor exposure. Inside, a 20 um hard-chrome plated rod and grease-storing piston seals keep friction low over millions of cycles.
