Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X900-10S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X900-10S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 900mm 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 JSIJ100X900-10S
The hard-anodized aluminum profile barrel leaves out external rods, making the body shorter and more compact than a same-bore ISO 15552 cylinder. A built-in magnet (-S) readies the unit for CMSE or DMSE sensors in the side grooves.
The external stop screw provides a 10 mm adjustment window, letting you fine-tune the extend end position down to 890 mm without swapping the cylinder; the retract end remains fixed. Air flows through a G1/2 port, and adjustable cushions decelerate the 32 mm rod at both ends. Note that the cushion only slows the piston; use an external rod lock or pilot-operated check valve to hold a load on air loss.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|

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 JSIJ100X900-10S Is Used
Pallet Transfer Stop
Fine-tune the 10 mm extend window to position a heavy pallet stop gate precisely on the line without remounting the actuator.
Clamp Position Trimming
Trim the extend stroke by up to 10 mm on-site to compensate for varying workpiece thicknesses in a heavy-duty clamping station.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X900-10S the Right Cylinder?
When sizing this 100 mm bore, stepping down to an 80 mm actuator drops the 0.5 MPa push force to 2513 N, while stepping up to 125 mm raises it to 6136 N. The 10 mm extend adjuster is ideal for sharing a spare across slightly different stroke variants or dialing in final tooling positions on-site. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. The -S magnet supports CMSE/DMSE switches. Because the 900 mm stroke is long, always support the load with 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 JSIJ100X900-10S 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 nominal 900 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 10 mm on-site, yielding a usable range of 890-900 mm. The retract end is fixed, and this mechanism sets end position rather than locking the load.
