Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X700-75S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X700-75S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 700mm 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 JSIJ100X700-75S
The hard-anodized aluminum profile barrel keeps the overall body shorter and more compact than a same-bore ISO 15552 cylinder. A built-in piston magnet (-S) allows CMSE or DMSE switches to drop directly into the side grooves for precise position detection.
The external stop screw provides a 75 mm adjustment window, letting you fine-tune the extend end position from 625 to 700 mm without swapping the cylinder. Air connects via the G1/2 port, and adjustable air cushions at both ends absorb the impact of heavy 100 mm pistons.

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 JSIJ100X700-75S Is Used
Press Tonnage Tuning
Dial in the exact 625 to 700 mm extend position on a heavy stamping press without machining new spacers, using the external 75 mm window to accommodate varying material thicknesses.
Heavy Lift Gate Actuation
Drive a vertical lifting gate on heavy machinery, taking advantage of the compact JIS profile to save space while the 100 mm bore provides the raw power needed for vertical lifting.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X700-75S the Right Cylinder?
The 75 mm adjustable window is highly useful for sharing one spare across multiple stroke variants or dialing in final end positions on-site. JSIJ mounting options include Basic, FA, LB, TC, TCM1, and TCM2. Because the 700 mm stroke creates a long lever arm, always use external guides to prevent rod bending and side-load damage.
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 JSIJ100X700-75S FAQ
The theoretical maximum force is 801 kgf at 1.0 MPa. The air port size is G1/2.
The external stop screw lets you shorten the extend stroke by up to 75 mm on-site, giving a usable extend range of 625 to 700 mm. The nominal 700 mm stroke is the maximum, and the retract end remains fixed. This stop sets the end position and does not hold the load on air loss.
