Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X125-75S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X125-75S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 125mm 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 JSIJ100X125-75S
The hard-anodized aluminum profile barrel keeps the body shorter and more compact than a same-bore ISO 15552 unit.
The external stop screw provides a 75 mm adjustable window, letting you shorten the extend stroke from the 125 mm maximum down to 50 mm without swapping the cylinder. Air connects via a G1/2 port, and the -S suffix means a built-in magnet is present for CMSE/DMSE sensors in the side grooves. A 33 mm adjustable air cushion decelerates the rod at each end, though a plain cylinder drifts on air loss, so fit an external rod lock for held loads.

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

| 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 JSIJ100X125-75S Is Used
Press Stroke Tuning
Dial in the exact 50 to 125 mm extend reach on a light stamping press without machining new spacers.
Pallet Stopper Gate
Adjust the stop position on the fly as pallet sizes change, using the 75 mm window to set the exact blocking point.
Vertical Lift Clamp
Lift a 200 kg fixture vertically and fine-tune the lower clamp position to clear varying product heights.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X125-75S the Right Cylinder?
The 75 mm adjust window is ideal for sharing one spare across multiple stroke variants or fine-tuning the end position during machine commissioning. Mounting choices include FA, LB, TC, TCM1, and TCM2. The -S magnet supports CMSE/DMSE switches. For any stroke at or over 300 mm, always guide the load to prevent side-load damage to the front cover.
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 JSIJ100X125-75S FAQ
At 0.5 MPa it pushes 3927 N and pulls 3574 N. At 0.7 MPa it pushes 5497 N and pulls 5003 N. The theoretical maximum force is 801 kgf at 1.0 MPa.
The nominal extend stroke is 125 mm. An external stop screw lets you shorten that extend travel on-site by up to 75 mm, giving a usable range of 50 to 125 mm. The retract end remains fixed.
