Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X800-30S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X800-30S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 800mm 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 JSIJ100X800-30S
The extruded hard-anodized aluminum barrel omits tie rods entirely, making the body shorter and more compact than a same-bore ISO 15552 unit.
A built-in piston magnet (-S) accepts CMSE/DMSE reed or electronic switches in the side grooves. The external adjuster lets you shorten the extend stroke on-site by up to 30 mm, giving a usable 770-800 mm range while the retract end stays fixed. Air connects via a G1/2 port, and adjustable 33 mm cushions decelerate the load at both ends.

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 JSIJ100X800-30S Is Used
Press Stroke Tuning
Fine-tune the 770-800 mm extend end position on-site by up to 30 mm to accommodate varying material thicknesses without repositioning the press cylinder.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X800-30S the Right Cylinder?
The adjustable stroke is ideal for sharing one spare across slightly different stroke variants or fine-tuning the extend end position without remounting the cylinder. JSIJ mounting choices include FA, LB, TC, TCM1, and TCM2. Because the 800 mm stroke is long, always use an external guide rail to prevent rod bending and side-load damage. The -S magnet is present for position 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 JSIJ100X800-30S FAQ
The theoretical maximum force is 801 kgf at 1.0 MPa. The air port size is G1/2.
The 800 mm nominal stroke is the maximum. An external stop screw lets you shorten the extend stroke on-site by up to 30 mm, yielding a usable extend range of 770-800 mm. The retract end remains fixed. This mechanism sets the end position and is not a load lock.
