Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X800-100S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X800-100S 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 JSIJ100X800-100S
Its extruded hard-anodized aluminum profile barrel makes it noticeably shorter than a same-bore ISO 15552 cylinder. The G1/2 port handles the required air volume for the 32 mm rod, while adjustable 33 mm cushions absorb end-of-stroke energy.
The -100 code means an external adjuster lets you shorten the extend stroke on-site by up to 100 mm, yielding a usable 700 to 800 mm range without changing the cylinder itself. This on-site end-position tuning is ideal for shared spares across stroke variants. The -S suffix provides a built-in piston magnet for CMSE/DMSE sensors in the side grooves.

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 JSIJ100X800-100S Is Used
Press Stroke Tuning
Fine-tune the 700 to 800 mm extend endpoint on-site to accommodate different material thicknesses in a forming press without swapping actuators.
Vertical Lift Stops
Set precise upper travel limits for a 200 kg material lift platform, tweaking the extend stroke window as payload dynamics change.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X800-100S the Right Cylinder?
This 100 mm model fits perfectly in the middle. The adjustable stroke is invaluable for fine-tuning the extend endpoint on-site or keeping one spare for multiple stroke variants. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2. Because the 800 mm stroke is long, always use an external guide to prevent rod bending and manage side loads. The -S magnet supports CMSE/DMSE switches.
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 JSIJ100X800-100S FAQ
The theoretical maximum force is 801 kgf at 1.0 MPa. It uses a G1/2 air port and a 32 mm piston rod.
The nominal 800 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke on-site by up to 100 mm, giving a usable range of 700 to 800 mm. The retract end is fixed. This stop sets the end position and is not a load lock.
