Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X900-40
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X900-40 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 JSIJ100X900-40
The hard-anodized aluminum extruded barrel contains no tie rods, and the G1/2 port feeds a 32 mm rod with an M26x1.5 thread. The JSIJ100X900-40 variant adds an external stop screw that lets you shorten the extend stroke on-site by up to 40 mm, meaning your usable forward travel spans 860 to 900 mm while the retract end remains fixed.
This on-site adjustability allows precise end-position tuning without physically swapping the cylinder, making it ideal for sharing a spare across stroke variants. Note that this specific SKU lacks a magnet and cannot accept CMSE or DMSE sensors; you would need the -S version for position detection.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3525 N | 3525 N |
| 0.7 MPa | 4935 N | 4935 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 JSIJ100X900-40 Is Used
Heavy Material Diversion
Tunes the 900 mm extend stroke on-site by up to 40 mm to align heavy diverters precisely on a conveyor belt without changing the cylinder.
Press Standby Station
Feeds heavy blanks into a press, relying on the external adjuster to dial in the exact 860 to 900 mm feed length required for different tooling.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X900-40 the Right Cylinder?
The 40 mm adjustable window is particularly useful when you need fine end-position tuning on-site or want a single spare to cover minor stroke differences. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. Because the stroke is 900 mm, you must support the load with external guides to prevent rod bending and manage side loads. Remember that a plain cylinder drifts on air loss, so install an external rod lock or pilot-operated check valve if the load must be held.
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 JSIJ100X900-40 FAQ
This 100 mm bore cylinder uses a G1/2 port and a 32 mm rod. The theoretical maximum force is 801 kgf at 1.0 MPa.
The -40 code means an external stop screw lets you shorten the extend stroke on-site by up to 40 mm. The nominal 900 mm stroke is the maximum, so the usable extend travel is 860 to 900 mm. The retract end is fixed, and the stop only sets the end position, acting as a cushion rather than a load lock.
