Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X225-100S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X225-100S 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 JSIJ100X225-100S
The hard-anodized aluminium extrusion omits tie rods entirely, and the G1/2 port feeds a 32 mm rod with an M26x1.5 thread. Because the -S suffix equips the piston with a magnet, you can drop CMSE or DMSE reed and electronic switches straight into the side grooves.
The -100 code defines an external stop-screw window that lets you shorten the extend stroke on-site by up to 100 mm, dropping the usable forward travel from the 225 mm maximum down to 125 mm without swapping the cylinder. The retract end remains fixed. Remember that the adjustable stop sets the end position; it is not a load lock, so you will need an external rod lock or pilot-operated check valve to hold a suspended load against air loss.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3525 N | 3525 N |
| 0.7 MPa | 4935 N | 4935 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 JSIJ100X225-100S Is Used
Press Stroke Tuning
Dial in the exact 125 to 225 mm extend position on-site via the external stop screw to accommodate varying material thicknesses in a light assembly press without changing the actuator body.
Transfer Diverter Setup
Adjust the extend endpoint on the fly to redirect packages of different sizes onto secondary conveyor lanes, using the 100 mm window to fine-tune the diverter arm reach.
Pallet Stop Calibration
Set the precise stopping height for pallets on a heavy-duty roller bed by shortening the forward stroke from the 225 mm maximum, ensuring stable positioning under high force.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X225-100S the Right Cylinder?
The external adjuster is ideal for machines where you need to fine-tune the extend endpoint on the floor or standardise one spare cylinder across several stroke variants. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. With a 225 mm stroke, you should guide the load to prevent excessive side-loading on the rod. The built-in magnet supports CMSE/DMSE sensors for position feedback.
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 JSIJ100X225-100S FAQ
At 0.7 MPa the push increases to 5497 N and the pull to 5003 N. The theoretical maximum force is 801 kgf at 1.0 MPa. It uses a G1/2 air port, a 32 mm rod, and features 33 mm adjustable air cushions at both ends.
The -100 indicates an external adjuster that allows you to shorten the extend stroke by up to 100 mm on-site. The nominal 225 mm stroke is the maximum, so you can set the usable forward travel anywhere between 125 mm and 225 mm. The retract end position is fixed. This mechanism only sets the end position and does not lock the load.
