Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X800-20S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X800-20S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 800mm 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 JSIJ100X800-20S
The hard-anodized extruded aluminum body houses a 32 mm rod, M26x1.5 rod thread, and G1/2 ports. A built-in piston magnet ships standard, ready to accept CMSE or DMSE reed and electronic switches directly in the side grooves.
The external stop screw lets you trim the extend stroke by up to 20 mm on site, giving a usable forward travel of 780 to 800 mm while the retract end remains fixed. Air cushions strike 33 mm at each end to decelerate the load, though a plain cylinder drifts on air loss, so fit an external rod lock or pilot-operated check valve if you need to hold a suspended load.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3525 N | 3525 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 JSIJ100X800-20S Is Used
Long-Stroke Press Tending
Uses the 800 mm reach to access deep press beds, while the 20 mm external adjuster fine-tunes the extraction position to match varying part widths.
Pallet Stop Gate
Deploys the 32 mm rod to halt heavy pallets on a line, using the on-site extend shortening to set the exact stop distance without changing mounts.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X800-20S the Right Cylinder?
The 20 mm adjustable window is ideal for sharing one spare across multiple stroke variants or dialing in final end positions on the machine. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. The -S suffix provides the integrated magnet for CMSE/DMSE sensors. Because the 800 mm stroke is long, always support the load with external guides to prevent rod bending and manage side loads.
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 JSIJ100X800-20S FAQ
The theoretical maximum is 801 kgf at 1.0 MPa. It uses a G1/2 port, a 32 mm rod with an M26x1.5 thread, and adjustable air cushions of 33 mm at both ends.
The nominal 800 mm stroke is the maximum forward travel. The external stop screw lets you shorten the extend stroke on site by up to 20 mm, giving a usable range of 780 to 800 mm. The retract end is fixed. This stop only sets the end position and does not lock the load.
