Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X800-30
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X800-30 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 JSIJ100X800-30
The hard-anodized aluminum profile barrel keeps the overall body shorter than a same-bore ISO 15552 unit.
This double-acting double-rod model uses a G1/2 port and an external adjuster to shorten the extend stroke on-site by up to 30 mm. The nominal 800 mm stroke remains the maximum, giving you a usable 770-800 mm range for fine-tuning the end position without swapping the cylinder. Note that this specific SKU lacks a magnet and cannot take CMSE/DMSE sensors.

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 JSIJ100X800-30 Is Used
Press Tonnage Calibration
Use the 30 mm extend window to dial in the exact contact point on a light assembly press without repositioning the entire fixture.
Long-Transfer Diverting
The 800 mm stroke reaches across a wide belt to push heavy pallets, while the adjustable stop absorbs minor variations in pallet length.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X800-30 the Right Cylinder?
The 30 mm extend-shortening window is ideal for sharing one spare across multiple stroke variants or making on-site end-position tweaks. You can mount it via FA, LB, TC, TCM1, or TCM2 brackets. Because this is an 800 mm stroke, always use external guides to prevent rod bending and side-load damage. Add an -S suffix if you need magnetic 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 JSIJ100X800-30 FAQ
The theoretical max force is 801 kgf at 1.0 MPa. This 100 mm bore unit uses a G1/2 port, has a 32 mm rod, and features 33 mm adjustable air cushions at both ends.
The external stop screw lets you shorten the extend stroke by up to 30 mm on-site, giving a usable range of 770-800 mm with the retract end fixed. This stop only sets the end position; it does not lock the load. If air is lost, the piston drifts, so you must add an external rod lock or pilot-operated check valve for load holding.
