Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X400-100S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X400-100S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 400mm 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 JSIJ100X400-100S
An external stop screw lets you fine-tune the extend end position without swapping the actuator, giving a usable extend range of 300-400 mm while the retract end remains fixed. The hard-anodized aluminium extruded barrel keeps the total envelope more compact than a same-bore ISO 15552 unit, and the G1/2 port handles the necessary air volume.
The built-in -S piston magnet accepts CMSE/DMSE sensors in the side grooves for precise positioning. Remember that the adjustable stop and air cushions only decelerate the piston; a plain cylinder drifts on air loss, so fit an external rod lock or pilot-operated check valve to hold a suspended load.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|

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 JSIJ100X400-100S Is Used
Press Stroke Calibration
Dial in the exact 300-400 mm extend position on-site using the external adjuster to set precise pressing depth without reprogramming the machine.
Variable Length Diverter
Fine-tune the divert arm reach by up to 100 mm to accommodate different package sizes on a single line using the magnetic position feedback.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X400-100S the Right Cylinder?
The -100 mm adjustable window is ideal when you need to share one spare across slight stroke variants or dial in a final end position on the machine. JSIJ mounting choices cover Basic, FA, LB, TC, TCM1, and TCM2. Because the 400 mm stroke creates leverage, always support the load with an external guide to prevent rod bending and premature seal wear.
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 JSIJ100X400-100S 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. This 100 mm bore unit uses a G1/2 air port, a 32 mm rod, and features 33 mm adjustable air cushions at both ends.
The 400 mm nominal stroke is the maximum extend length. The external adjuster lets you shorten the extend stroke by up to 100 mm on-site, yielding a usable range of 300-400 mm for exact end-position tuning. The retract end is fixed, and the adjuster sets the stop point—it does not lock or hold the load.
