Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X225-75S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X225-75S 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 JSIJ100X225-75S
The extruded hard-anodized aluminium profile barrel keeps the overall body shorter and more compact than a same-bore ISO 15552 cylinder. It uses a G1/2 port and a 32 mm rod with an M26x1.5 thread.
The external stop screw lets you trim the extend stroke on-site by up to 75 mm, giving a usable forward travel of 150 to 225 mm while the retract end stays fixed. This on-site tuning is ideal for dialing in exact end positions without swapping the cylinder. The -S suffix adds a built-in piston magnet for CMSE/DMSE sensors.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3525 N | 3525 N |

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 JSIJ100X225-75S Is Used
Press Clamping
Fine-tune the 150 to 225 mm extend reach on-site to seat parts perfectly in a press without machining new spacers.
Divertor Arm
Dial in the exact push distance for varying product widths on a packaging line using the 75 mm external stop screw.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X225-75S the Right Cylinder?
The 75 mm adjuster window makes this model highly versatile for sharing as a spare across machines that need slightly different extend endpoints within that 150 to 225 mm range. You can mount it using FA, LB, TC, TCM1, or TCM2 brackets. The included -S magnet supports CMSE/DMSE switches for position sensing. Because the 225 mm stroke exceeds 300 mm only slightly, side-load guides are recommended for long-life rod bearing wear prevention.
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 JSIJ100X225-75S 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. This 100 mm bore model uses a G1/2 air port.
The nominal extend stroke is 225 mm, which is the maximum travel. An external stop screw lets you shorten the forward stroke on-site by up to 75 mm, giving a usable extend range of 150 to 225 mm. The retract end is fixed, and this mechanism sets end position rather than holding the load.
