Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X350-100S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X350-100S 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 JSIJ100X350-100S
The hard-anodized aluminum barrel omits tie rods entirely, making the body noticeably shorter and more compact than a same-bore ISO 15552 unit. A built-in magnet (-S) allows CMSE or DMSE sensors to drop directly into the side grooves for precise position detection.
With a nominal 350 mm stroke, the usable extend range is 250-350 mm while the retract end remains fixed, letting you fine-tune the end position without swapping the cylinder. The G1/2 port feeds the 32 mm rod, and adjustable 33 mm air cushions at both ends decelerate the load smoothly. Note that the cushion only decelerates; an external rod lock or pilot-operated check valve is required to hold a load on air loss.

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 JSIJ100X350-100S Is Used
Press Fit Tuning
Dial in the exact 250-350 mm insertion depth for pressing bearings without machining custom spacers or changing the actuator body.
Variable Transfer Reject
Adjust the extend stroke on-site to push mixed-size products off a line at different distances using a single cylinder profile.
Pallet Stop Adjustment
Fine-tune the stopping position for various pallet widths by turning the external adjuster rather than repositioning the whole mount.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X350-100S the Right Cylinder?
The JSIJ series supports Basic, FA, LB, TC, TCM1, and TCM2 mounts. The -100 mm adjustable window is ideal for sharing a spare across stroke variants or finalizing end-position tuning on-site. Because the 350 mm stroke generates leverage, always use external guides to prevent rod bending and side loads. The included -S magnet supports reed or electronic switches for closed-loop control.
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 JSIJ100X350-100S FAQ
At 0.5 MPa it pushes 3927 N and pulls 3574 N. At 0.7 MPa it pushes 5497 N and pulls 5003 N. The theoretical maximum is 801 kgf at 1.0 MPa. It uses a G1/2 port, a 32 mm rod, and 33 mm adjustable cushions at both ends.
The external stop screw lets you shorten the extend stroke on-site by up to 100 mm, giving a usable extend range of 250-350 mm from the 350 mm nominal maximum. The retract end is fixed. This mechanism only sets the end position and does not lock the load.
