Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X700-20S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X700-20S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 700mm 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 JSIJ100X700-20S
The hard-anodized aluminum extruded body is noticeably shorter than a same-bore ISO 15552 unit, saving valuable machine space. Air connects via a G1/2 port.
The -20 code means an external adjuster can shorten the extend stroke by up to 20 mm on site, giving a usable range of 680 to 700 mm while the retract end stays fixed. You can fine-tune the end position without physically swapping the cylinder. The -S suffix adds a piston magnet for CMSE/DMSE sensors in the side grooves. Remember that the adjustable stop sets position only; it does not hold load on air loss, so use an external rod lock for vertical holding.

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 JSIJ100X700-20S Is Used
Heavy Pallet Diverter
Pushes loaded pallets off a high-speed line. The 20 mm extend adjuster lets you dial in the exact push distance to match varying pallet widths without changing the cylinder.
Press Fit Positioning
Moves heavy assemblies into a press station. Fine-tuning the extend end position on site prevents over-travel and crushing of components during setup.
Multi-Size Carton Stop
Acts as a hard stop for large cartons on a gravity roller conveyor. The external adjuster allows operators to shorten the stroke slightly for mixed carton sizes on the same line.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X700-20S the Right Cylinder?
When sizing this 100 mm bore, stepping down to an 80 mm unit drops the 0.5 MPa push force to 2513 N, while moving up to a 125 mm bore raises it to 6136 N. The adjustable stroke is ideal for sharing one spare cylinder across machines that need slightly different end positions within that 20 mm window. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. The built-in magnet supports CMSE/DMSE switches for position feedback. Because the 700 mm stroke is long, always use an external guide rail to prevent rod bending and side-load damage.
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 JSIJ100X700-20S FAQ
The theoretical maximum force is 801 kgf at 1.0 MPa. The air port size is G1/2.
The nominal 700 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 20 mm on site, giving a usable extend range of 680 to 700 mm. The retract end remains fixed. This mechanism sets the end position but does not lock the load.
