Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X25-30
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X25-30 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 25mm 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 JSIJ100X25-30
The hard-anodized aluminum extruded body makes it shorter and more compact than a same-bore ISO 15552 unit.
The external adjuster lets you fine-tune the extend end position on-site without swapping the cylinder, shortening the stroke by up to 30 mm from the 25 mm nominal maximum. Air connects via a G1/2 port, and adjustable 33 mm cushions decelerate the load at both ends. Note that this plain SKU lacks a magnet and cannot take CMSE or DMSE sensors.

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 JSIJ100X25-30 Is Used
Press Pin Insertion
Dial in the exact seating depth of a heavy pin using the 30 mm adjuster window, preventing over-travel on high-force insertion tasks.
Heavy Stamping Stop
Fine-tune the downstroke end position on-site for a 200 kg vertical stamping head without changing the physical cylinder mounting.
Pallet Alignment
Absorb slight height differences in incoming pallets by backing off the extend stroke a few millimeters at the workstation.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X25-30 the Right Cylinder?
The adjustable stroke is ideal for sharing a spare across stroke variants or dialing in exact end positions on-site. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Because this specific SKU has no -S magnet, it cannot support position sensing. For any stroke over 300 mm, always use a guide rail to prevent side-load damage.
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 JSIJ100X25-30 FAQ
The theoretical maximum force is 801 kgf at 1.0 MPa. The air port size is G1/2.
The 25 mm nominal stroke is the maximum extend length. The external stop screw lets you shorten that extend travel on-site by up to 30 mm, allowing fine-tuning of the end position. The retract end remains fixed. This mechanism only sets position and does not lock the load.
