Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X200-75S
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X200-75S 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 JSIJ63X200-75S
The -75 code means an external adjuster can shorten the extend stroke on site by up to 75 mm, giving a usable range of 125 to 200 mm without changing the cylinder itself. This on-site tuning is perfect for dialing in end positions, and the built-in magnet supports CMSE/DMSE sensors in the side grooves.
The G3/8 port feeds the double-acting double rod, and adjustable 29 mm air cushions at both ends decelerate the payload smoothly. Remember the stop screw sets position only; it is not a load lock, so fit an external rod lock or pilot-operated check valve if you need to hold a load on air loss.

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 JSIJ63X200-75S Is Used
Press Fit Dialing
Use the 75 mm extend adjuster to fine-tune the exact pressing depth of a 1559 N insertion head on-site without swapping cylinders or adding shims.
Variable Transfer Stops
Set the retract stop position for different product lengths on a packaging line, shifting the 200 mm extend stroke down to 125 mm as needed.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X200-75S the Right Cylinder?
The adjustable stroke shines when you need to fine-tune the extend end position on-site or want a single spare cylinder that covers 125 to 200 mm variants. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. The -S suffix means the piston magnet is present for CMSE/DMSE switches; without it you cannot add sensors. For any stroke at or over 300 mm, always guide the load to prevent side-load wear on the rod seals.
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 JSIJ63X200-75S FAQ
The nominal 200 mm stroke is the maximum. An external adjuster lets you shorten the extend stroke by up to 75 mm on site, giving a usable extend range of 125 to 200 mm. The retract end is fixed, and this stop only sets position—it will not hold a load on air loss.
