Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X450-20
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X450-20 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 JSIJ100X450-20
Its extruded hard-anodized aluminium barrel omits tie rods, making the body shorter and more compact than a same-bore ISO 15552 unit.
The JSIJ100X450-20 features an external stop screw that lets you shorten the extend stroke on-site by up to 20 mm, giving a usable range of 430-450 mm without changing the cylinder itself. Nominal stroke is the maximum, while the retract end remains fixed. This non-magnetic SKU cannot take a sensor; you would need the -S variant for CMSE/DMSE switches. Note that the adjustable air cushions only decelerate the load near the ends, 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 |

| 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 JSIJ100X450-20 Is Used
Press Stroke Tuning
Fine-tune the extend end position by up to 20 mm on-site to accommodate different material thicknesses without swapping the cylinder.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X450-20 the Right Cylinder?
The -20 mm adjustable window is ideal for fine-tuning the extend end position on-site or sharing a single spare across multiple stroke variants. JSIJ mounting options include Basic, FA, LB, TC, TCM1, and TCM2. Because the 450 mm stroke creates a long lever arm, always use external guides to prevent rod bending and side loads. As a non-magnet SKU, it cannot accept position sensors.
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 JSIJ100X450-20 FAQ
The theoretical maximum force is 801 kgf at 1.0 MPa. This 100 mm bore cylinder uses a G1/2 port, a 32 mm rod, and features 33 mm adjustable air cushions at both ends.
The external stop screw lets you shorten the extend stroke on-site by up to 20 mm, giving a usable extend range of 430-450 mm. The nominal 450 mm stroke is the maximum, and the retract end is fixed. This mechanism only sets the end position and does not lock the load.
