Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X200-20S
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X200-20S 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 JSIJ63X200-20S
The hard-anodized aluminum barrel keeps the overall body shorter and more compact than a same-bore ISO 15552 unit, while the G3/8 port matches the bore's air flow needs. An external stop screw lets you trim the extend stroke by up to 20 mm on site, meaning the usable forward travel spans 180 to 200 mm and the retract end remains fixed.
This built-in adjuster allows fine end-position tuning without swapping the cylinder, and the -S suffix indicates a piston magnet for CMSE/DMSE sensors. Remember that the adjustable stop sets the end position but does not lock the load; a plain cylinder drifts on air loss, so fit an external rod lock or pilot-operated check valve for held loads.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1402 N | 1402 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 JSIJ63X200-20S Is Used
Press Fit Tuning
Dial in the exact 180 to 200 mm extend reach for seating bearings without machining custom spacers.
Transfer Diverter
Adjust the pusher end-stop on-site to handle varying package widths on a mid-power sorting line.
Pallet Stop Gate
Fine-tune the stopping position of pallets on a roller bed by trimming the forward stroke up to 20 mm.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X200-20S the Right Cylinder?
The 20 mm adjuster is ideal for sharing a single spare across multiple stroke variants or fine-tuning the end position during machine commissioning. You can mount it via FA, LB, TC, TCM1, or TCM2 brackets, and the -S magnet works directly with CMSE/DMSE switches in the side grooves. For any stroke at or over 300 mm, always guide the load to prevent side-load damage to 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.
