Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X1000-20
The AirTAC Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X1000-20 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 1000mm 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 JSIJ100X1000-20
Delivering 3927 N of push force at 0.5 MPa, this 100 mm bore JIS profile cylinder brings heavy-duty actuation into a compact footprint that is notably shorter than a same-bore ISO 15552 unit. The hard-anodized aluminium barrel keeps the assembly light while handling serious work. With a practical safe working load of about 2356 N, it can lift roughly 200 kg vertically using a 2:1 safety margin.
The -20 code denotes an external adjuster that lets you shorten the extend stroke on-site by up to 20 mm, yielding a usable range of 980 to 1000 mm without swapping the cylinder. It connects via a G1/2 port and relies on a 33 mm adjustable air cushion at each end to decelerate the payload. Note that this SKU lacks a magnet and cannot take a CMSE or DMSE sensor; for the -S variant adds magnetic sensing.

Where the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X1000-20 Is Used
Press Stroke Calibration
Dial in the exact 980 to 1000 mm end position on-site with the external adjuster to set precise press depth without changing the physical cylinder limits.
Heavy Vertical Lift
Lift approximately 200 kg of material vertically, leveraging the 3927 N push force while external guides handle the 1000 mm rod extension.
Long-Reach Transfer
Push heavy pallets or chassis components along a conveyor, using the compact JIS profile to save valuable machine length compared to standard ISO units.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X1000-20 the Right Cylinder?
When sizing, the neighbouring 80 mm bore yields 2513 N push at 0.5 MPa, while the massive 125 mm bore provides 6136 N, so the 100 mm bore sits perfectly in the middle for loads around 2356 N. The adjustable stroke is ideal for fine-tuning the end position on-site or keeping a shared spare across similar stroke variants. Mounting options include FA, LB, TC, TCM1, and TCM2. Because this is a 1000 mm stroke, you must use external guides to prevent rod bending and manage side loads. Remember that the cushion only decelerates; use an external rod lock or pilot-operated check valve if you need to hold a load on air loss.
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 JSIJ100X1000-20 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. This 100 mm bore cylinder uses a G1/2 port.
The external stop screw lets you shorten the extend stroke by up to 20 mm on-site. The usable extend range is 980 to 1000 mm, with the 1000 mm nominal stroke being the maximum. The retract end remains fixed, and the stop sets position rather than locking the load.
