Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X275-100S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X275-100S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 275mm 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 JSIJ100X275-100S
The hard-anodized aluminum barrel makes it shorter and more compact than a same-bore ISO 15552 unit.
A built-in piston magnet (-S) allows CMSE or DMSE switches to drop directly into the side grooves for precise position sensing. The external adjuster lets you shorten the extend stroke on-site by up to 100 mm, giving a usable range of 175 to 275 mm without changing the cylinder itself. Air connects via a G1/2 port, and the retract end remains fixed.

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 JSIJ100X275-100S Is Used
Press Stroke Tuning
Fine-tune the 275 mm extend down to 175 mm on-site to set precise material contact depth without swapping the actuator.
Pallet Positioning
Adjust the end stop to handle varying pallet heights dynamically, using the 100 mm window for exact placement.
Diverter Gate Control
Shift the extend position within the 175 to 275 mm range to route different package sizes on a high-speed line.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X275-100S the Right Cylinder?
For lighter push needs under 2500 N at 0.5 MPa, step down to the 80 mm bore; if your application requires over 5497 N at 0.7 MPa, move up to the 125 mm bore. The 100 mm adjustable window is ideal for sharing one spare cylinder across multiple stroke variants or fine-tuning the extend end position on-site. Mounting options include FA, LB, TC, TCM1, and TCM2. Because the stroke is 275 mm, ensure adequate external guidance to prevent side-loading damage to the rod. The -S magnet supports CMSE/DMSE 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 JSIJ100X275-100S FAQ
The theoretical maximum force is 801 kgf at 1.0 MPa. The air port size is G1/2.
The external stop screw shortens the extend stroke by up to 100 mm on-site, giving a usable extend range of 175 to 275 mm. The nominal 275 mm is the maximum, and the retract end is fixed. This stop sets the end position and is not a load lock.
