Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X400-100S
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X400-100S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm bore and 400mm 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 JSIJ63X400-100S
The hard-anodized aluminum extrusion omits tie rods entirely for a clean exterior. A built-in magnet (-S) allows CMSE or DMSE switches to drop directly into the side grooves for precise position detection.
The -100 code means an external adjuster can shorten the extend stroke by up to 100 mm on site, giving a usable forward range of 300 to 400 mm while the retract end remains fixed. You can fine-tune the end position without physically remounting the actuator. Pneumatic connections use a G3/8 port, and adjustable air cushions of 29 mm decelerate the load at both ends.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|

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 JSIJ63X400-100S Is Used
Transfer Push-Off
Adjusts the push-off distance on the fly to clear different carton widths without swapping the actuator.
Clamp Stroke Tuning
Dials in the exact forward clamping position for varying part thicknesses directly at the fixture.
Lowering Stop Limit
Sets a precise intermediate lowering depth on a vertical press without repositioning the cylinder body.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X400-100S the Right Cylinder?
The adjustable stroke is ideal when you need to share a spare cylinder across several stroke variants or fine-tune a final end position on the machine. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Because this is a 400 mm stroke, you must support the load with external guides to prevent rod bending and excessive side loading. The -S suffix ensures the piston magnet is present for sensors.
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 JSIJ63X400-100S FAQ
The theoretical maximum force is 318 kgf at 1.0 MPa. The air port size is G3/8.
An external stop screw lets you shorten the extend stroke by up to 100 mm on site, giving a usable forward range of 300 to 400 mm. The nominal 400 mm stroke is the maximum. The retract end is fixed. This mechanism sets the end position but does not lock the load; use an external rod lock or pilot-operated check valve if you need to hold a load on air loss.
