Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X900-20
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X900-20 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 JSIJ100X900-20
The hard-anodized aluminum extruded barrel houses a 32 mm rod, and the G1/2 port handles the high air volume needed for rapid cycling. It is a double-acting, double-rod actuator built for rigorous industrial environments.
The -20 suffix denotes an external adjuster that lets you shorten the extend stroke on-site by up to 20 mm, giving a usable forward travel of 880 to 900 mm while the retract end remains fixed. Note that this specific SKU lacks a magnet and cannot support CMSE/DMSE sensors; add an -S variant if you require position detection. Furthermore, the adjustable stop only sets end position—it is not a load lock, so fit an external rod lock or pilot-operated check valve if you need to hold a load against gravity.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3525 N | 3525 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 JSIJ100X900-20 Is Used
Pallet Diversion
Handles large pallet transfers over a 900 mm span, where the compact JIS profile saves valuable machine footprint compared to standard ISO 15552 cylinders.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X900-20 the Right Cylinder?
The adjustable stroke feature is particularly useful when you need on-site end-position tuning or want a shared spare across slightly different stroke variants. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. Because this is a 900 mm stroke, you must account for side-load and rod-bending risks by guiding the load externally to prevent premature seal wear. Finally, remember this non-magnetic SKU cannot accept a sensor; choose the -S version if your control system requires CMSE or DMSE switches.
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 JSIJ100X900-20 FAQ
The theoretical maximum force is 801 kgf at 1.0 MPa. It features a 32 mm rod, M26x1.5 rod thread, G1/2 air port, and 33 mm adjustable air cushions at both ends.
The external adjuster allows you to shorten the extend stroke by up to 20 mm on-site, meaning the usable forward travel is 880 to 900 mm. The nominal 900 mm stroke is the maximum, and the retract end remains fixed. This mechanism only sets the end position and does not lock the load.
