Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X175-75
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X175-75 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 JSIJ100X175-75
Its external adjuster allows the 175 mm extend stroke to be shortened on-site by up to 75 mm, yielding a usable 100 to 175 mm window while the retract end remains fixed. Built with an extruded hard-anodized aluminum barrel, the body is noticeably shorter and more compact than a same-bore ISO 15552 unit.
The adjustable air cushions provide 33 mm of deceleration at each end. Note this specific SKU lacks a magnet, so it cannot take CMSE or DMSE sensors without switching to the -S variant.

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 JSIJ100X175-75 Is Used
Press Stroke Tuning
Dial in the exact 100 to 175 mm extend position on-site to accommodate material thickness variations without swapping the actuator.
Divertor Adjustment
Shorten the extend stroke by up to 75 mm to reposition a diverting jaw for different package sizes on the fly.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X175-75 the Right Cylinder?
The 100 mm bore hits a sweet spot for medium-heavy loads. The 75 mm adjustable window is invaluable when you want a shared spare across slightly different stroke variants or need to fine-tune the extend end without remounting the cylinder. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2. Because the 175 mm stroke exceeds 300 mm, always guide the load to prevent rod side-loading. As a non-magnetized unit, position sensing is unavailable.
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 JSIJ100X175-75 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. This 100 mm bore unit uses a G1/2 port.
The nominal 175 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke on-site by up to 75 mm, giving a usable range of 100 to 175 mm. The retract end is fixed. This mechanism sets the end position and does not lock the load.
