Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X50-10
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X50-10 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 50mm 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 JSIJ100X50-10
The hard-anodized aluminum barrel is noticeably shorter than an equivalent ISO 15552 unit, saving machine space without losing power.
The -10 code means an external adjuster can shorten the extend stroke by up to 10 mm on-site, letting you fine-tune the end position from 40 to 50 mm without swapping the cylinder. Air connects via a G1/2 port. Note that this plain SKU lacks a magnet and cannot take a CMSE or DMSE sensor. The retract end is fixed, and the adjustable air cushions only decelerate the load; use an external rod lock or pilot-operated check valve if you need to hold a load on air loss.

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 JSIJ100X50-10 Is Used
Press Fit Tuning
Use the 10 mm extend adjuster to dial in the exact bottoming position for pressing bearings, ensuring perfect insertion without re-mounting the actuator.
Pallet Stop Adjust
Acts as a robust pallet stop where the external adjuster fine-tunes the stopping distance by up to 10 mm to accommodate varying package sizes on the line.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X50-10 the Right Cylinder?
The 10 mm adjustable window is ideal when you need to share a spare cylinder across slightly different stroke variants or fine-tune a final end position on the machine. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2. Because this is a non-magnet SKU, you cannot fit position sensors; choose an -S variant if you need CMSE or DMSE switches. While side loads should generally be guided, always ensure adequate external guidance for any application approaching or exceeding 300 mm strokes.
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 JSIJ100X50-10 FAQ
The theoretical maximum force is 801 kgf at 1.0 MPa.
The nominal 50 mm extend stroke is the maximum. The external adjuster lets you shorten the extend stroke by up to 10 mm on-site, giving a usable range of 40 to 50 mm. The retract end remains fixed.
