Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X50-50S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X50-50S 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 MACJ63X50-50S
The MACJ63X50-50S pairs a riveted stainless round barrel with a hard-chrome plated rod, so it shrugs off the damp and light washdown that wreck painted mini cylinders. Inside, the piston runs double-acting with a variable air cushion at both ends, and the extend stroke carries a 50 mm on-site trim window - the whole 50 mm can be shortened at the external stop screw without swapping the unit.
At 0.5 MPa this bore pushes 1558 N and pulls 1457 N; plan real work around 935 N of that rating. In lifting terms it raises roughly 159 kg at full pressure, or about 79 kg vertically with a 2:1 margin. Air supply runs 0.15-1.0 MPa (22-145 psi) and stroke speed spans 30-800 mm/s.

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 MACJ63X50-50S Is Used
Fixture clamping on a CNC machining centre
With 935 N of practical push at 0.5 MPa, the clamp holds aluminium or steel parts against cut forces, and the 50 mm trim window lets you retune the clamp point when a new fixture goes on.
Part ejection from a stamping die
A variable cushion at the retract end stops the ejector plate from slamming home at high speed, while the stainless barrel tolerates lubricant mist around the press.
Product stop gate on a bottling conveyor
The stop screw sets the gate throw to the exact lane height, and washdown-friendly stainless construction survives the wet zones that peel paint off ordinary minis.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X50-50S the Right Cylinder?
Sizing check: the next bore down, 50 mm, delivers 981 N push and 881 N pull at 0.5 MPa, so step down only if your load needs under about 580 N of working force; bore 63 is the largest MA frame, so nothing bigger exists in this series. The stop screw sets the extend endpoint and behaves like a mechanical end stop, not a mid-stroke brake - expect drift if air is lost. FA flange and LB foot mountings bolt straight on, rod knuckles I or Y suit linkages, and the built-in magnet takes CMSG, DMSG or EMSG switches with no special piston order.
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 MACJ63X50-50S FAQ
At 0.5 MPa it pushes 1558 N and pulls 1457 N. At 0.7 MPa those figures climb to 2181 N and 2040 N, and the theoretical maximum is 317.7 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with speeds of 30-800 mm/s.
The stainless barrel is rolled directly onto the aluminium covers, eliminating tie-rod joints that loosen under vibration. The 16 mm hard-chrome rod resists scoring, and the two-way piston seal stores grease for longer service between overhauls.
