Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X80-30S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X80-30S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 80mm 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 JSIJ100X80-30S
The hard-anodized aluminum profile barrel keeps the overall length shorter than a same-bore ISO 15552 unit. A G1/2 port feeds the chamber, and the integrated -S magnet allows CMSE/DMSE sensors to drop directly into the side grooves for position detection.
The -30 code means an external adjuster can shorten the extend stroke on site by up to 30 mm, giving a usable forward travel range of 50 to 80 mm while the retract end remains fixed. This lets you fine-tune the end position without physically swapping the cylinder.

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 JSIJ100X80-30S Is Used
Press Fit Tuning
Dial in the exact 50 to 80 mm insertion depth for bearing presses without machining new hard stops.
Variable Diverter Arm
Adjust the extend reach on a sorting gate on-site to handle changing package widths on the line.
Pallet Stop Positioning
Fine-tune the physical stop location for different pallet sizes while retaining the full retract distance.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X80-30S the Right Cylinder?
The adjustable stroke is ideal when you need on-site end-position tuning or want a shared spare across slightly different stroke variants. JSIJ mounting choices include FA, LB, TC, TCM1, and TCM2. The -S suffix equips the piston with a magnet for reed or electronic sensors. Because the 80 mm stroke is under 300 mm, side-load stress is minimal, but always guide the load on longer strokes.
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 JSIJ100X80-30S FAQ
The theoretical maximum force is 801 kgf at 1.0 MPa.
The nominal 80 mm stroke is the maximum forward travel. The external adjuster lets you shorten the extend stroke on site by up to 30 mm, yielding a usable range of 50 to 80 mm. The retract end is fixed, and this stop only sets position; it does not lock the load.
