Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X900-75
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X900-75 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 900mm 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 JSIJ100X900-75
The extruded hard-anodized aluminum profile barrel makes the body shorter than a same-bore ISO 15552 cylinder, saving valuable machine space without sacrificing power.
The -75 code defines an external adjuster window that lets you shorten the extend stroke on site by up to 75 mm, giving a usable forward travel range of 825 to 900 mm while the retract end remains fixed. You can fine-tune the end position without physically swapping the cylinder. Air connects via a G1/2 port, and adjustable air cushions of 33 mm at each end absorb the impact of moving loads. This base SKU lacks a magnet, so it cannot accept CMSE or DMSE sensors; adding the -S variant enables that switching capability.

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 JSIJ100X900-75 Is Used
Press Tool Positioning
Dial in the exact 825 to 900 mm extend reach on-site to seat heavy press tools, using the 75 mm adjustment window to compensate for fixture tolerances.
Heavy Rack Loading
Index heavy containers into storage racks, relying on the compact JIS profile to fit within tight vertical lift stations.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X900-75 the Right Cylinder?
The 100 mm bore sits in the heavy-duty class, offering 5497 N at 0.7 MPa. The adjustable stroke feature is highly useful when you need to share a spare cylinder across slightly different stroke variants or perform on-site end-position tuning without machining. JSIJ mounting options include Basic, FA, LB, TC, TCM1, and TCM2. Because the 900 mm stroke is long, always use external guides to prevent rod bending and manage side loads. Remember that a plain cylinder drifts on air loss; the cushion only decelerates, so fit an external rod lock or pilot-operated check valve if you need to hold a load.
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 JSIJ100X900-75 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 900 mm nominal stroke is the maximum. An external stop screw lets you shorten the extend stroke on-site by up to 75 mm, providing a usable range of 825 to 900 mm. The retract end is fixed, and this stop sets position only; it does not lock the load.
