Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X300-40S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X300-40S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 300mm 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 JSIJ100X300-40S
The hard-anodized aluminum barrel keeps the overall body shorter than a same-bore ISO 15552 unit, while the G1/2 port handles the necessary air volume. With a built-in magnet, it hosts CMSE/DMSE switches directly in the side grooves.
The external stop screw provides a 40 mm adjustment window, letting you fine-tune the extend end position from 260 to 300 mm on-site without swapping the actuator. Note that the retract end remains fixed, and the adjustable cushion only decelerates the load rather than holding it.

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 JSIJ100X300-40S Is Used
Press Tonnage Calibration
Dial in the exact 260 to 300 mm extend reach on-site to seat materials precisely without reprogramming the machine cycle.
Multi-Point Diverting
Adjust the extend stop individually at each lane to handle varying package sizes on a single shared conveyor framework.
Pallet Positioning Stops
Fine-tune the physical end-stop location for different pallet depths while relying on the 100 mm bore to absorb heavy impacts.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X300-40S the Right Cylinder?
The 40 mm adjustable window is ideal when you need to synchronize end positions across multiple stations or standardize a shared spare across stroke variants. Mounting options include FA, LB, TC, TCM1, and TCM2. Because this is a 300 mm stroke, always support the load with external guides to prevent rod bending and side-load wear. The -S suffix ensures you have the magnet required for 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 JSIJ100X300-40S FAQ
The theoretical maximum force is 801 kgf at 1.0 MPa. It uses a G1/2 air port, a 32 mm rod, and features 33 mm adjustable air cushions at both ends.
The 300 mm nominal stroke is the maximum extend length. An external adjuster lets you shorten the extend stroke by up to 40 mm, giving a usable range of 260 to 300 mm for fine-tuning the end position. The retract end is fixed, and this stop mechanism decelerates the load but does not lock it.
