Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X450-10S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X450-10S 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 JSIJ100X450-10S
The hard-anodized aluminum extruded barrel contains no external tie rods, and the G1/2 port feeds a 32 mm piston rod threaded M26x1.5.
The -10 suffix provides an external adjuster that lets you shorten the extend stroke by up to 10 mm on site, giving a usable range of 440 to 450 mm without changing the cylinder body. A built-in magnet (-S) allows CMSE or DMSE sensors to drop directly into the side grooves.

Specifications follow the official AirTAC JSI (JIS standard) datasheet. Confirm against the product label before installation. Thread options: PT (blank) / G. Barrel: hard-anodized aluminum profile (no tie rods).
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 JSIJ100X450-10S Is Used
Press Stroke Tuning
Fine-tune the final 10 mm of a clamping press extension on site to accommodate different material thicknesses without swapping the actuator.
Vertical Lift Stop
Lift loads up to 200 kg in a vertical elevator, using the external stop screw to precisely set the upper travel limit within the 450 mm window.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X450-10S the Right Cylinder?
When sizing this actuator, stepping down to an 80 mm bore drops the 0.5 MPa push force to 2513 N, while moving up to a 125 mm bore increases it to 6136 N. The 10 mm adjustable window is ideal for sharing a single spare across multiple stroke variants or fine-tuning a machine stop on site. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. The -S magnet supports CMSE/DMSE switches. Because the 450 mm stroke is long, 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 JSIJ100X450-10S FAQ
The theoretical maximum is 801 kgf at 1.0 MPa. The air port is G1/2.
The nominal 450 mm extend stroke is the maximum. The external adjuster lets you shorten the extend stroke by up to 10 mm on site, yielding a usable range of 440 to 450 mm. The retract end is fixed. This stop only sets the end position; it is not a load lock, so use an external rod lock or pilot-operated check valve to hold a load.
