Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X900-100S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X900-100S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 900mm 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 JSIJ100X900-100S
The hard-anodized aluminium extrusion keeps the assembly light, while the G1/2 port feeds a 32 mm rod. A built-in magnet (-S) fits CMSE/DMSE switches directly into the side grooves for exact position detection.
The external stop screw lets you trim the extend stroke by up to 100 mm on site, giving a usable forward travel of 800 to 900 mm without swapping the cylinder. The retract end remains fixed. This adjuster sets the end position; it is not a load lock, so fit an external rod lock or pilot-operated check valve if you need to hold a vertical load against air loss.

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 JSIJ100X900-100S Is Used
Long-Transfer Push-Off
Pushes heavy pallets off a main conveyor line, using the 100 mm window to dial in the exact 850 mm eject distance on site without re-mounting the actuator.
Adjustable Lowering Press
Lowers a 200 kg assembly head into a fixture, relying on the stop screw to set the precise 820 mm descent depth while the cushion decelerates the approach.
High-Bay Storage Extractor
Extracts totes from deep racking by extending up to 900 mm, with the built-in magnet confirming full extension and the external adjuster compensating for shelf depth differences.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X900-100S the Right Cylinder?
The -100 mm adjuster is ideal when you need to fine-tune a long 900 mm end position on site or share a single spare cylinder across multiple stroke variants. Mounting choices span FA, LB, TC, TCM1, and TCM2. Because the 900 mm stroke is long, always support the rod against side-load bending and use an external guide rail to prevent premature 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 JSIJ100X900-100S FAQ
The theoretical maximum is 801 kgf at 1.0 MPa. The air port is G1/2.
The nominal 900 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 100 mm on site, yielding a usable forward travel of 800 to 900 mm. The retract end is fixed, and the stop only sets position rather than locking the load.
