Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X400-30S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X400-30S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 400mm 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 JSIJ100X400-30S
Its extruded hard-anodized aluminum barrel keeps the total length shorter than a same-bore ISO 15552 unit. The integrated -S magnet allows CMSE/DMSE sensors to drop directly into the side grooves for precise end-of-stroke detection.
The external adjuster lets you shorten the extend stroke on site by up to 30 mm, giving a usable range of 370-400 mm without swapping the cylinder. Pneumatic connections use a G1/2 port, and the retract end remains fixed while you fine-tune the extend position.

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 JSIJ100X400-30S Is Used
Press Tonnage Trimming
Dial in the exact 370-400 mm extend position on a heavy stamping press to accommodate different material thicknesses without remounting the actuator.
Pallet Stopper Calibration
Adjust the end stop on-site by up to 30 mm to handle varying pallet depths in a high-throughput distribution hub.
Heavy Fixture Positioning
Shift a 200 kg machining fixture precisely into place, relying on the 100 mm bore for the necessary push force.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X400-30S the Right Cylinder?
The 30 mm adjustable window is ideal for sharing a single spare across slightly different stroke variants or fine-tuning end positions on the machine. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Because the 400 mm stroke creates leverage, always use an external guide to prevent rod bending and side loads.
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 JSIJ100X400-30S FAQ
The theoretical maximum force is 801 kgf at 1.0 MPa.
The nominal 400 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke on site by up to 30 mm, yielding a usable range of 370-400 mm. The retract end is fixed. This mechanism sets the end position and does not lock the load; use an external rod lock or pilot-operated check valve to hold a load securely, as the air cushion only decelerates.
