Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X450-40
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X450-40 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 JSIJ100X450-40
Its extruded hard-anodized aluminium barrel omits tie rods entirely, making the overall body shorter and more compact than a same-bore ISO 15552 unit. The G1/2 port handles high airflow to keep the 30-800 mm/s speed range responsive.
The external stop screw lets you trim the extend stroke by up to 40 mm on-site, giving a usable 410-450 mm end-position window while the retract end stays fixed. Note that this specific SKU lacks a magnet, so it cannot take CMSE/DMSE sensors; choose 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 JSIJ100X450-40 Is Used
Press Stroke Calibration
Dial in the exact 410-450 mm extend position on-site to set precise material contact depth without machining new stop collars.
Heavy Vertical Lowering
Lower 200 kg payloads smoothly using the 33 mm adjustable air cushions at both ends to absorb kinetic energy before the end of travel.
Multi-Part Diverter
Adjust the extend reach on the fly to deflect different box sizes on a packaging line while maintaining a fixed retract position.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X450-40 the Right Cylinder?
The 40 mm adjustable window is ideal when you need to share one spare cylinder across several stroke variants or dial in a precise end-stop on the machine. Mounting options include FA, LB, TC, TCM1, and TCM2. Because the 450 mm stroke creates leverage, always support the load with an external guide to prevent rod bending and side-load 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 JSIJ100X450-40 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, with a theoretical max of 801 kgf at 1.0 MPa. It features a 32 mm rod, M26x1.5 rod thread, G1/2 port, and 33 mm adjustable cushions.
The external adjuster shortens the extend stroke by up to 40 mm on-site, giving a 410-450 mm range while keeping the retract end fixed. The stop sets the end position but is not a load lock; on air loss the piston drifts. For held loads use an external rod lock or pilot-operated check valve.
