Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X450-40S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X450-40S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 450mm 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 JSIJ100X450-40S
The hard-anodized aluminum extrusion keeps the total envelope more compact than a same-bore ISO 15552 unit, while the G1/2 port handles the required air volume. A built-in magnet (-S) allows CMSE/DMSE sensors to drop directly into the side grooves for precise end-of-stroke detection.
The external stop screw provides a 40 mm on-site extend-shortening window, letting you dial the usable stroke down from the 450 mm maximum to 410 mm without swapping the actuator. The retract end remains fixed, and the adjustable air cushions absorb kinetic energy at the extremes. Remember that this stop 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 load on 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 JSIJ100X450-40S Is Used
Press Tool Positioning
Fine-tune the 450 mm extend stroke by up to 40 mm on-site to set precise bottom-dead-center on heavy stamping tools without machining new spacers.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X450-40S the Right Cylinder?
The 40 mm adjustable window is ideal when you need to fine-tune the extend end position on-site or want a shared spare across slightly different stroke variants. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Because the 450 mm stroke creates a long lever arm, always support the load with an external guide to prevent rod bending and excessive side loading. The -S magnet version supports reed or electronic 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 JSIJ100X450-40S FAQ
The theoretical maximum force is 801 kgf at 1.0 MPa. This 100 mm bore actuator uses a G1/2 air port, a 32 mm rod, and M26x1.5 rod-end threads.
The nominal 450 mm stroke is the maximum extend length. An external stop screw lets you shorten the extend stroke on-site by up to 40 mm, giving a usable range of 410 to 450 mm. The retract end remains fixed. This mechanism sets the end position and does not lock the load.
