Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X800-10S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X800-10S 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 JSIJ100X800-10S
The hard-anodized aluminium extrusion keeps the assembly light, while the G1/2 port feeds enough volume for a 30-800 mm/s speed range.
The JSIJ100X800-10S uses an external stop screw to trim the extend stroke by up to 10 mm on site, giving a usable forward travel of 790-800 mm without swapping the cylinder; the retract end remains fixed. A built-in piston magnet (-S) accepts CMSE/DMSE reed or electronic switches in the side grooves for precise positioning. Note that the adjustable cushion only decelerates the load near the ends; fit an external rod lock or pilot-operated check valve if you need to hold a load against air loss.

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 JSIJ100X800-10S Is Used
Heavy Pallet Lifts
Raises 200 kg loaded pallets vertically, using the 10 mm adjuster to dial in the exact upper stop without repositioning the cylinder.
Long-Reach Diverters
Pushes heavy cartons across an 800 mm wide belt, relying on the 33 mm adjustable cushions to decelerate the 32 mm rod smoothly.
Press Feed Clamping
Holds large steel blanks in place during stamping, using the G1/2 port to deliver rapid clamping force across the long stroke.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X800-10S the Right Cylinder?
When sizing this 100 mm bore, stepping down to an 80 mm cylinder drops the 0.5 MPa push force to 2513 N, while moving up to a 125 mm bore increases it to 6136 N. The 10 mm extend-shortening window is ideal for sharing a single spare across machines that need slightly different end positions, letting you fine-tune the 800 mm travel on the floor. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. The -S suffix means the magnet is already present for CMSE/DMSE sensors. Because the 800 mm stroke is long, always support the rod against side-load bending and use an external guide rail to prevent premature seal wear.
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 JSIJ100X800-10S FAQ
The theoretical maximum force is 801 kgf at 1.0 MPa.
The external stop screw lets you shorten the extend stroke by up to 10 mm on site, giving a usable forward travel of 790-800 mm. The nominal 800 mm stroke is the maximum, and the retract end is fixed. This mechanism sets the end position and does not lock the load.
