Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X225-50S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X225-50S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 225mm 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 JSIJ100X225-50S
The external stop screw lets you shorten the forward travel by up to 50 mm, yielding a usable 175-225 mm range while the retract end remains fixed. You can fine-tune the end position without swapping the cylinder. The extruded hard-anodized aluminium barrel omits tie rods entirely, making the body shorter and more compact than a same-bore ISO 15552 unit.
This SKU includes the -S piston magnet for CMSE/DMSE switches that drop directly into the side sensor grooves. Air connects via a G1/2 port, and adjustable air cushions of 33 mm at each end absorb kinetic energy near stroke ends. Remember that a standard cylinder does not hold load on air loss; the cushion only decelerates. For a suspended load, fit an external rod lock or a pilot-operated check valve.

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

| 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 JSIJ100X225-50S Is Used
Press Tooling Trim
Fine-tune the 175-225 mm extend stroke on-site to set the exact contact depth for forming or stamping operations without machining a new stop.
Pallet Stop Gate
Shorten the extend stroke dynamically to index pallets of varying lengths, relying on the compact JIS profile to save floor space.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X225-50S the Right Cylinder?
The -50 mm adjustable window is ideal when you need to share one spare cylinder across several stroke variants or trim the end position on-site. Mounting options cover Basic, FA, LB, TC, TCM1, and TCM2. The -S magnet supports CMSE/DMSE sensors. For any stroke at or above 300 mm, always guide the load to prevent rod side-load and premature seal wear.
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 JSIJ100X225-50S 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. It uses a G1/2 port.
The nominal 225 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 50 mm on-site, giving a usable range of 175-225 mm. The retract end is fixed. This stop sets the end position and is not a load lock.
