Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X300-100S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X300-100S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 300mm stroke, G1/2 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 JSIJ100~125 Adjustable Cylinder JSIJ100X300-100S
Its extruded hard-anodized aluminium barrel omits tie rods entirely, making the body shorter and more compact than a same-bore ISO 15552 unit. The G1/2 port handles high flow, while the integrated -S magnet allows CMSE/DMSE sensors to drop directly into the side grooves for precise position detection.
The external adjuster lets you shorten the extend stroke on-site by up to 100 mm, meaning the usable extend range is 200-300 mm without swapping the cylinder. This on-site tuning is ideal for shared spares across stroke variants. The retract end remains fixed, and the 33 mm adjustable air cushions decelerate the load smoothly.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3525 N | 3525 N |
| 0.7 MPa | 4935 N | 4935 N |
| Max (@1.0 MPa) | 719 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 JSIJ100~125 Adjustable Cylinder JSIJ100X300-100S Is Used
Press Stroke Tuning
Dial in the exact 200-300 mm extend reach on-site using the external adjuster to accommodate varying material thicknesses without changing the cylinder.
Heavy Diverting
Shorten the extend stroke by up to 100 mm on-site to adapt the diverter arm length for different package sizes on the fly.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X300-100S the Right Cylinder?
The adjustable stroke is perfect for fine-tuning the extend end position on-site or keeping one spare for multiple stroke variants. It supports FA, LB, TC, TCM1, and TCM2 mounts. Because the stroke is 300 mm, always use an external guide rail to prevent rod bending and absorb side loads. The included -S magnet supports CMSE/DMSE switches for direct sensing.
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 JSIJ100~125 Adjustable Cylinder JSIJ100X300-100S FAQ
The theoretical maximum force is 801 kgf at 1.0 MPa. It uses a G1/2 port and a 33 mm adjustable cushion at both ends.
The nominal 300 mm stroke is the maximum. The external adjuster lets you shorten the extend stroke on-site by up to 100 mm, giving a usable extend range of 200-300 mm. The retract end is fixed. This mechanism sets the end position and is not a load lock; use an external rod lock or pilot-operated check valve to hold a load.
