Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X300-100
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X300-100 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 JSIJ100X300-100
The hard-anodized aluminum barrel leaves out external rods, making the overall body shorter than a same-bore ISO 15552 cylinder.
The -100 code means an external stop screw lets you shorten the extend stroke on site by up to 100 mm, dropping the usable extension from the 300 mm maximum down to 200 mm without changing the cylinder itself. The retract end stays fixed. Air connects via a G1/2 port, and adjustable air cushions of 33 mm sit at both ends. Note this SKU lacks a magnet, so it cannot take a CMSE or DMSE sensor.

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 JSIJ100X300-100 Is Used
Press Tonnage Adjustment
Use the external adjuster to dial in the exact 200 to 300 mm extend reach for light pressing tasks, ensuring parts bottom out correctly without re-mounting the actuator.
Multi-Position Diverting
Set the extend stroke precisely at the machine to deflect products of varying widths down a secondary lane, using the fixed retract end as a consistent home position.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X300-100 the Right Cylinder?
The adjustable stroke is ideal when you need to fine-tune the extend end position on site or want a shared spare across slightly different stroke variants. Mounting options include FA, LB, TC, TCM1, and TCM2. Because the 300 mm stroke is fairly long, always support the rod against side-load bending with an external guide. Without a -S suffix, this specific unit cannot host a magnetic sensor.
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 JSIJ100X300-100 FAQ
The theoretical maximum force is 801 kgf at 1.0 MPa. The air port size is G1/2.
The 300 mm nominal stroke is the maximum extension. The external adjuster lets you shorten the extend stroke on site by up to 100 mm, giving a usable extend range of 200 to 300 mm. The retract end is fixed. This mechanism sets the end position and does not hold the load on air loss; for load holding you need an external rod lock or pilot-operated check valve.
