Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X350-10S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X350-10S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 350mm 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 JSIJ100X350-10S
The hard-anodized aluminium extruded barrel contains no external tie rods, and the G1/2 port handles the high air volume needed for rapid cycling. A built-in magnet equips the unit for CMSE or DMSE position switches that mount directly into the side grooves.
The -10 code defines an external adjuster that lets you shorten the extend stroke by up to 10 mm on site, giving a usable range of 340 to 350 mm while the retract end remains fixed. Note that the adjustable stop only sets the end position; it does not hold the load on air loss, so fit an external rod lock or pilot-operated check valve for vertical safety.

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 JSIJ100X350-10S Is Used
Press Stroke Tuning
Dial in the exact 340 to 350 mm extend position on a stamping or clamping press without machining new hard stops.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X350-10S the Right Cylinder?
The 100 mm bore sits in the heavy-force bracket, and the 10 mm extend-shortening window is ideal for sharing a spare across slightly different stroke variants or finalizing end positions during machine commissioning. JSIJ mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. Because the stroke is 350 mm, always support the load with an external guide rail to prevent rod bending and premature seal wear from side loads. The integrated -S magnet supports reed and electronic sensors for precise end-position confirmation.
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 JSIJ100X350-10S FAQ
At 0.7 MPa the push is 5497 N and the pull is 5003 N. The theoretical maximum force is 801 kgf at 1.0 MPa. The air port is G1/2, the rod is 32 mm, and the rod-end thread is M26x1.5.
The -10 code means an external stop screw lets you shorten the extend stroke by up to 10 mm on site. The usable extend range is 340 to 350 mm, with the 350 mm nominal stroke acting as the maximum. The retract end is fixed, and the stop only sets the end position rather than locking the load.
