Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X100-20
The AirTAC Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X100-20 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 100mm 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 JSIJ100X100-20
Generating 3927 N of push force at 0.5 MPa, this 100 mm bore profile cylinder brings heavy-duty actuation into a JIS footprint that is noticeably shorter than a same-bore ISO 15552 unit. The hard-anodized aluminium barrel keeps the assembly light while handling a safe working load of about 2356 N, which translates to lifting roughly 200 kg vertically with a 2:1 margin. Air connects via a G1/2 port.
The JSIJ100X100-20 code means the 100 mm nominal extend stroke can be shortened by up to 20 mm on-site via an external adjuster, letting you fine-tune the end position without swapping the cylinder. This SKU lacks a magnet and cannot take CMSE or DMSE sensors, so order an -S variant if you need position detection. Note that a plain cylinder drifts on air loss; the adjustable cushion only decelerates near the end, so fit an external rod lock or pilot-operated check valve for held loads.

Where the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X100-20 Is Used
Press Stroke Tuning
Dial in the exact 80 to 100 mm extend contact point on a light assembly press without machining new spacers.
Vertical Load Lowering
Lower heavy fixtures weighing up to 200 kg, relying on the 33 mm adjustable air cushions to decelerate the impact at the fixed retract end.
Divertor Positioning
Set precise diverting arm extension limits on-site to accommodate different package sizes on a packing line.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X100-20 the Right Cylinder?
When sizing, the 80 mm bore offers 2513 N push at 0.5 MPa if your load is lighter, while stepping up to 125 mm yields 6136 N for heavier demands. The 20 mm extend-shortening window is ideal for sharing a spare across stroke variants or finalizing end positions during machine commissioning. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Because this is a non-magnet SKU, position sensing is not possible without moving to an -S version. For any stroke at or above 300 mm, always guide the load to prevent side-load damage to the rod seal.
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 JSIJ100X100-20 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 air port size is G1/2.
The nominal 100 mm extend stroke is the maximum. The external adjuster lets you shorten the extend stroke by up to 20 mm on-site, giving a usable extend range of 80 to 100 mm. The retract end remains fixed, and the adjuster sets the end position rather than locking the load.
