Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X900-30
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X900-30 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 JSIJ100X900-30
Its extruded hard-anodized aluminum barrel keeps the overall body shorter and more compact than a same-bore ISO 15552 unit. The G1/2 port feeds the 32 mm rod to generate substantial thrust.
The external adjuster lets you shorten the extend stroke on-site by up to 30 mm, giving a usable range of 870-900 mm without changing the cylinder itself. Note this plain SKU lacks a magnet and cannot take CMSE/DMSE sensors; the -S variant is required for switching.

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 JSIJ100X900-30 Is Used
Press Stroke Tuning
Fine-tune the 870-900 mm extend end position on-site to accommodate different material thicknesses in a large forming press without swapping cylinders.
Long-Reach Diversion
Actuate a large diverter arm over a 900 mm conveyor belt, using the external adjuster to dial in the exact contact point for various package sizes.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X900-30 the Right Cylinder?
Step down to an 80 mm bore for 2513 N if the load permits, or step up to 125 mm for 6136 N. The 30 mm adjust window is ideal for sharing a spare across stroke variants and fine-tuning the end position on-site. Mounting options include FA, LB, TC, TCM1, and TCM2. Because the stroke is 900 mm, always use an external guide to prevent rod bending and manage side loads. Remember this no-S SKU cannot accept a sensor.
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 JSIJ100X900-30 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 cylinder uses a G1/2 air port and a 32 mm rod with an M26x1.5 thread.
The nominal 900 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke on-site by up to 30 mm, yielding a usable range of 870-900 mm, while the retract end remains fixed. This stop only sets the end position; it is not a load lock. The air cushion only decelerates the piston, so for a held load you must use an external rod lock or pilot-operated check valve.
