Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X200-50S
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X200-50S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm bore and 200mm stroke, G3/8 air ports and adjustable end cushioning. Its no-tie-rod, hard-anodized profile barrel is more compact than an ISO 15552 cylinder of the same bore — a space-saver on tight machines.

About the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X200-50S
An external stop screw lets you shorten the extend stroke by up to 50 mm, giving a usable range of 150 to 200 mm while the retract end remains fixed. The nominal 200 mm stroke is the maximum travel. This on-site adjustability means you can fine-tune the stroke without swapping the cylinder, and the hard-anodized aluminum extruded barrel is notably shorter than a same-bore ISO 15552 unit.
The integrated -S piston magnet supports CMSE and DMSE reed or electronic switches that mount directly into the side grooves. It connects via a G3/8 port and features a 20 mm rod with an M18x1.5 thread. Note that the adjustable stop sets the end position only; it does not hold the load on air loss, so you will need an external rod lock or pilot-operated check valve for suspended loads.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1402 N | 1402 N |
| 0.7 MPa | 1962 N | 1962 N |
| Max (@1.0 MPa) | 286 kgf | |
JSIJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative).

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X200-50S Is Used
Adjustable Clamping Press
Dial in the exact 150 to 200 mm extend position on-site to clamp varying material thicknesses without re-engineering the fixture.
Dynamic Transfer Divert
Fine-tune the divert stroke length by up to 50 mm to accommodate different package sizes on a packaging line.
Vertical Lift Gate
Safely lift gates weighing up to 79 kg using the 63 mm bore, adjusting the end-stop to prevent over-travel.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X200-50S the Right Cylinder?
The 63 mm is the sweet spot for medium-duty tasks needing around 1559 N. The 50 mm adjustable window is ideal when you need to share a spare cylinder across slightly different stroke variants or dial in a final position after mechanical assembly. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. The -S magnet allows for direct CMSE/DMSE sensors. Because the 200 mm stroke is relatively short, side-load stress is minimal, but always guide the load for any stroke over 300 mm.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 Set cushions to minimum, then release gradually.
- check Use correct mounting accessory (LB/FA/FB/CA/CB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X200-50S FAQ
This 63 mm bore cylinder uses a G3/8 port.
The external stop screw lets you shorten the extend stroke by up to 50 mm on-site. The usable extend range is 150 to 200 mm, with 200 mm being the maximum nominal stroke. The retract end is fixed, and the stop only sets position—it does not lock the load.
