Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X700-20
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X700-20 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 700mm 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 JSIJ100X700-20
Air connects via a G1/2 port, and the 32 mm rod uses an M26x1.5 thread.
The -20 code means an external adjuster can shorten the 700 mm extend stroke on-site by up to 20 mm, yielding a usable range of 680 to 700 mm for fine-tuning the end position without swapping the cylinder. The retract end remains fixed, and the 33 mm adjustable air cushions at both ends decelerate the load smoothly. This plain SKU lacks a magnet and cannot take CMSE or DMSE sensors, so order an -S variant if you need position detection.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3525 N | 3525 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 JSIJ100X700-20 Is Used
Press Stroke Calibration
Dial in the exact 680 to 700 mm extend end-position on a large forming press without machining new spacers or changing the cylinder.
Pallet Positioning Stop
Fine-tune the stopping point of heavy 200 kg pallet loads on a conveyor by adjusting the external stop screw within the 20 mm window.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X700-20 the Right Cylinder?
The 20 mm adjustable window is ideal for sharing a spare across stroke variants or finalizing end positions on-site. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2. Because the 700 mm stroke is long, always use an external guide to prevent rod bending and side-load damage. Remember that a plain cylinder drifts on air loss; use an external rod lock or pilot-operated check valve if the load must be held.
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 JSIJ100X700-20 FAQ
At 0.5 MPa it pushes 3927 N and pulls 3574 N. At 0.7 MPa it pushes 5497 N and pulls 5003 N. The theoretical maximum force is 801 kgf at 1.0 MPa. The air port size is G1/2.
The 700 mm nominal stroke is the maximum. The external adjuster lets you shorten the extend stroke on-site by up to 20 mm, giving a usable extend range of 680 to 700 mm. The retract end is fixed, and this stop only sets the end position; it is not a load lock.
