Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X175-100S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X175-100S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 175mm 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 JSIJ100X175-100S
The external adjuster lets you tune the usable extend stroke down from the 175 mm maximum to 75 mm without changing the unit itself, while the retract end remains fixed. The hard-anodized aluminum extruded barrel makes the body shorter and more compact than a same-bore ISO 15552 cylinder.
Equipped with a built-in piston magnet (-S), the unit accepts CMSE or DMSE reed and electronic sensors that drop directly into the side grooves. Pneumatic connections use a G1/2 port, and adjustable air cushions of 33 mm at each end absorb impact energy. The stop screw sets the end position but is not a load lock; a plain cylinder drifts on air loss, so fit an external rod lock or pilot-operated check valve if you need to hold a suspended load.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|

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 JSIJ100X175-100S Is Used
Press Fit Tuning
Dial in the exact seating depth of a bearing press by adjusting the extend stroke from 175 mm down to 75 mm on the fly.
Variable Transfer Stops
Act as a raised physical stop on a heavy-duty belt line, tweaking the protrusion distance to match different product widths.
Pallet Positioning
Push pallets into a strapping station, using the external adjuster to set the final alignment position without swapping actuators.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X175-100S the Right Cylinder?
The 100 mm adjustable window is ideal for sharing one spare cylinder across multiple stroke variants, as you can fine-tune the extend end position on the floor. Mounting choices include Basic, FA, LB, TC, TCM1, and TCM2 brackets. The included -S magnet enables position sensing. Because the stroke is 175 mm, guide the load to prevent side-load wear on the rod seals.
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 JSIJ100X175-100S FAQ
The theoretical maximum force is 801 kgf at 1.0 MPa.
The nominal 175 mm stroke is the maximum extend length. The external adjuster lets you shorten the extend stroke on-site by up to 100 mm, giving a usable extend range of 75 to 175 mm. The retract end is fixed, and the adjuster sets the end position rather than locking the load.
