Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X100-30
The AirTAC Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X100-30 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 JSIJ100X100-30
Delivering 3927 N of push force at 0.5 MPa, this 100 mm bore JIS profile cylinder brings heavy-duty actuation into a footprint noticeably shorter than a same-bore ISO 15552 unit. The hard-anodized aluminum barrel keeps the assembly light, while the G1/2 port matches the bore's air demand. An external adjuster lets you trim the extend stroke by up to 30 mm on site, dropping the usable forward travel from the 100 mm maximum down to 70 mm without swapping the cylinder.
This on-site tuning means you can fine-tune the end position to hit a mechanical stop precisely, and one spare can cover several stroke variants. Based on the 0.5 MPa push rating, it handles a safe working load of about 2356 N, which translates to lifting roughly 200 kg vertically with a 2:1 margin. Note that this plain SKU lacks a magnet, so it cannot take a CMSE or DMSE sensor; add the -S variant if you need position detection.

Where the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X100-30 Is Used
Press Stroke Tuning
Dial in the exact 70 to 100 mm extend contact point on a light assembly press without machining new spacers.
Variable Transfer Stop
Act as an adjustable flight stop on a conveyor, trimming the 30 mm window to accommodate different product lengths on the fly.
Pallet End Positioning
Push pallets to a precise datum, using the external screw to compensate for mechanical wear over time.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X100-30 the Right Cylinder?
Size this 100 mm bore against its neighbours: a 125 mm bore gives 6136 N push at 0.5 MPa for heavier loads, while an 80 mm bore offers 2513 N if you want a smaller footprint. The adjustable stroke shines when you need to dial in the extend end position on the machine or want a single spare covering 70 to 100 mm travels. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2. Because this is a no-S model, it cannot host a magnetic switch. For any application, guide the load to prevent side-loading; while not strictly required at 100 mm, a guide is mandatory for any stroke reaching 300 mm or more.
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 JSIJ100X100-30 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. This 100 mm bore uses a G1/2 port.
The 100 mm nominal stroke is the maximum. The external adjuster lets you shorten the extend stroke by up to 30 mm on site, giving a usable extend range of 70 to 100 mm. The retract end is fixed. This mechanism sets the end position and decelerates the load, but it is not a load lock; use an external rod lock or pilot-operated check valve to hold a load on air loss.
