Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X350-75
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X350-75 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 350mm 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 JSIJ100X350-75
Air connects via a G1/2 port, and the M26x1.5 rod end drives a 32 mm piston shaft.
An external stop screw provides a 75 mm on-site adjustment window, letting you fine-tune the extend stroke anywhere from 275 mm up to the 350 mm maximum without swapping the cylinder. The retract end remains fixed. Note this plain SKU lacks a magnet and cannot take a CMSE or DMSE sensor; for that you need the -S variant. Also, the adjustable air cushions only decelerate the load near the stroke ends, so fit an external rod lock or pilot-operated check valve if you need to hold a load on air loss.

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 JSIJ100X350-75 Is Used
Press Stroke Tuning
Dial in the exact 275 to 350 mm extend position on a light-duty assembly press without machining new spacers or changing the actuator.
Diverter Gate Actuation
Fine-tune the gate extension distance on a sorting line to handle varying product sizes without reprogramming the machine cycle.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X350-75 the Right Cylinder?
When sizing this 100 mm bore, step down to an 80 mm cylinder if your 0.5 MPa push requirement is under 2513 N, or step up to a 125 mm bore if you need more than 6136 N. The 75 mm adjustable window is ideal when you need to dial in the exact extend end-position on the machine or want a single spare part that covers several stroke lengths. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. Because this is a non-sensing SKU without a magnet, you cannot add position switches; order the -S version if your control system requires CMSE or DMSE feedback. Finally, with a 350 mm stroke, always support the load against side-load and rod-bending forces using external guide rails to prevent premature seal wear.
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 JSIJ100X350-75 FAQ
The theoretical maximum force is 801 kgf at 1.0 MPa. The air port size is G1/2.
An external stop screw lets you shorten the extend stroke on-site by up to 75 mm. The usable extend range is 275 mm to the 350 mm maximum, while the retract end is fixed. This mechanism sets the end position but does not lock the load.
