Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X500-30
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X500-30 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 500mm 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 JSIJ100X500-30
The extruded hard-anodized aluminum profile barrel leaves out external tie rods entirely, making the body noticeably shorter and more streamlined than a same-bore ISO 15552 cylinder.
The -30 code defines an external adjuster window that lets you shorten the extend stroke on-site by up to 30 mm, yielding a usable forward travel of 470 to 500 mm while the retract end remains fixed. You can fine-tune the end position without physically swapping the cylinder. Pneumatic connections use a G1/2 port, and adjustable air cushions of 33 mm at each end absorb shock. Note that this SKU lacks a magnet and cannot take a CMSE or DMSE sensor; for that capability, specify the -S variant.

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 JSIJ100X500-30 Is Used
Press Stroke Calibration
Dial in the exact 470 to 500 mm extend position on-site to set precise pressing depth without machining custom spacers or changing the actuator body.
Pallet Stopper Adjustment
Fine-tune the stopping point for varying pallet sizes on a conveyor line by simply turning the external adjuster rather than repositioning the entire mount.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X500-30 the Right Cylinder?
The adjustable stroke is highly useful when you need to share a single spare cylinder across several stroke variants or dial in a precise end position on the machine. Mounting choices include Basic, FA, LB, TC, TCM1, and TCM2. Because this is a 500 mm stroke, you must support the load with external guides to prevent rod bending and excessive side loading. Remember that a plain cylinder drifts on air loss; use 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 JSIJ100X500-30 FAQ
The theoretical maximum force is 801 kgf at 1.0 MPa. The air port size is G1/2.
The nominal stroke is 500 mm, which is the maximum extend travel. The external -30 adjuster allows you to shorten the extend stroke on-site by up to 30 mm, giving a usable range of 470 to 500 mm. The retract end is fixed, and the adjuster sets the end position but does not lock the load.
