Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X275-10S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X275-10S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 275mm 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 JSIJ100X275-10S
The hard-anodized aluminium extruded barrel omits tie rods, making the overall body shorter and more compact than a same-bore ISO 15552 unit.
A built-in piston magnet (-S) allows CMSE or DMSE switches to drop directly into the side sensor grooves. The external adjuster provides a 10 mm on-site extend-shortening window, letting you fine-tune the end position from 265 to 275 mm without swapping the cylinder. Air connects via a G1/2 port, and adjustable cushions decelerate the load at both ends.

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 JSIJ100X275-10S Is Used
Press Clamping
Dial in the exact 265 to 275 mm clamping depth on a heavy press fixture using the external stop screw, ensuring consistent part holding without reprogramming the machine.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X275-10S the Right Cylinder?
The 10 mm adjuster is ideal when you need to share one spare cylinder across several stroke variants or dial in a precise end stop on-site. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Because the 275 mm stroke exceeds 300 mm, ensure you use a guide rail to prevent side-load damage to the rod seal.
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 JSIJ100X275-10S 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 air port size is G1/2.
The 275 mm nominal stroke is the maximum extend length. An external stop screw lets you shorten the extend stroke by up to 10 mm on-site, giving a usable range of 265 to 275 mm. The retract end is fixed, and this mechanism only sets the end position; it does not lock the load.
