Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X175-40
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X175-40 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 175mm 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 JSIJ100X175-40
You get a usable forward travel of 135-175 mm, letting you fine-tune the end position without swapping the cylinder. The hard-anodized aluminum profile barrel keeps the overall body shorter than a same-bore ISO 15552 unit, saving machine footprint. Air connects via a G1/2 port.
The external stop screw sets the forward endpoint, but it is not a load lock; the retract end remains fixed. Because this specific SKU lacks a magnet, it cannot take a CMSE or DMSE sensor. The adjustable air cushions provide 33 mm of deceleration at each end, yet the cylinder will drift on air loss, so add 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 JSIJ100X175-40 Is Used
Press Fit Tuning
Dial in the exact 135-175 mm insertion depth for bearing presses without machining custom spacers.
Variable Diverter Gate
Adjust the extend stop on-site to reroute different package sizes on a packaging line.
Pallet Stop Positioning
Fine-tune the end stop location for various pallet widths while utilizing the full 100 mm bore force.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X175-40 the Right Cylinder?
The 40 mm adjuster window is ideal when you need to tune the exact extend endpoint on-site or want a single shared spare across slightly different 135-175 mm stroke variants. You can mount this JIS profile cylinder using basic, FA, LB, TC, TCM1, or TCM2 brackets. Since the 175 mm stroke is below the 300 mm threshold, side-load guide requirements are minimal. Note that without the -S suffix, this version cannot support magnetic sensing.
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 JSIJ100X175-40 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 maximum force is 801 kgf at 1.0 MPa. The rod is 32 mm with an M26x1.5 thread.
The nominal 175 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 40 mm on-site, giving a usable range of 135-175 mm. The retract end is fixed, and the stop only sets the end position, it does not lock the load.
