Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X350-40
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X350-40 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 JSIJ100X350-40
The hard-anodized aluminum extruded barrel contains no external tie rods, keeping the body smooth and rigid. Air connects via a G1/2 port, and the 32 mm piston rod carries an M26x1.5 thread.
The -40 suffix denotes an external adjuster that lets you shorten the extend stroke on-site by up to 40 mm, yielding a usable extend range of 310 to 350 mm while the retract end remains fixed. You can fine-tune the end position without swapping the cylinder, which is ideal for shared spares across stroke variants. Note this SKU lacks a magnet and cannot take a CMSE or DMSE sensor.

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 JSIJ100X350-40 Is Used
Press Stroke Tuning
Dial in the exact 310 to 350 mm extend contact point on a light assembly press without machining new hard stops.
Divertor Arm Adjustment
Fine-tune the extend reach of a heavy divertor arm on-site to accommodate different package widths.
Pallet Stop Positioning
Set the precise end position for a pallet stop gate and easily readjust it if the pallet format changes later.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X350-40 the Right Cylinder?
The JSIJ series supports Basic, FA, LB, TC, TCM1, and TCM2 mounts. The adjustable stroke is invaluable for on-site end-position tuning or using one spare across multiple stroke variants. Because this is a 350 mm stroke, you must account for side-load risks and use external guides to prevent rod bending. To add magnetic sensing, you must select the -S version, as this base SKU cannot accept a switch.
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 JSIJ100X350-40 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 max force is 801 kgf at 1.0 MPa. It uses a G1/2 port, a 32 mm rod with an M26x1.5 thread, and has 33 mm adjustable air cushions at both ends.
The nominal 350 mm stroke is the maximum extend length. The external adjuster lets you shorten the extend stroke by up to 40 mm on-site, giving a usable range of 310 to 350 mm. The retract end is fixed. This mechanism only sets the end position; it does not lock the load, so you need an external rod lock or pilot-operated check valve to hold a load on air loss.
