Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X200-50S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X200-50S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø63mm bore and 200mm 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 MACJ63X200-50S
A 50 mm trim range makes the MACJ63X200-50S the most flexible stop-set cylinder in this bore class: shorten the 200 mm extend stroke by up to 50 mm after the machine is built, yet still command 1557.9 N of push at 0.5 MPa, or 2181 N at 0.7 MPa. For daily sizing, budget about 935 N of working force, which vertically lifts roughly 79 kg with a 2:1 margin.
The stainless barrel is rolled and riveted onto the aluminium covers, so the body stays sealed and rigid in vibrating plant air. Both ends carry a variable cushion to soften stops across the 30-800 mm/s speed range, and the standard magnet drops straight into CMSG / DMSG / EMSG switch brackets. Supply 0.15-1.0 MPa (22-145 psi).

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 MACJ63X200-50S Is Used
Stacker Z-axis stop
Set exact stack height with the 50 mm window; about 79 kg of vertical lift capacity covers loaded pallet slugs on small palletisers.
Case squaring station
1558 N of push at 0.5 MPa squares carton flaps before taping, and the dual cushions prevent bounce against the adjusted stop.
Waterworks gate positioner
The stainless barrel and chrome rod endure humid valve pits, and the 50 mm trim sets final gate open position without shims.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X200-50S the Right Cylinder?
Step down to a 50 mm MACJ (981.3 N push at 0.5 MPa) if your load sits near 550 N of working force; for more force than this 63 mm bore provides, change the bore, since 63 mm is the largest in the series. The stop screw is a mechanical extend stop - if air pressure drops the rod is free to move, so hold loads with a valve or external lock instead.
FA flange and LB foot bases plus I / Y rod knuckles suit most frames. On a 200 mm stroke, guide any off-axis load externally to protect the rod and seals.
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 MACJ63X200-50S FAQ
1557.9 N push and 1457.4 N pull at 0.5 MPa, rising to 2181 N push and 2040.3 N pull at 0.7 MPa, with a theoretical maximum of 317.7 kgf at 1.0 MPa. Bore 63 mm, 1/4" ports, 50 mm adjustable extend window, double-acting with variable cushions, speed 30-800 mm/s.
No. The variable air cushion at both ends works independently of the 50 mm stop screw, so even at a heavily shortened extend stroke the piston still decelerates smoothly across 30-800 mm/s before seating on the mechanical stop.
