Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X400-10
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X400-10 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 400mm 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 JSIJ100X400-10
The hard-anodized aluminium barrel houses a 32 mm rod and uses a G1/2 port.
The external stop screw lets you trim the extend stroke by up to 10 mm on-site, giving a usable 390-400 mm range while the retract end stays fixed. You can fine-tune the end position without physically swapping the cylinder. Note that this SKU lacks a magnet and cannot take a CMSE or DMSE sensor; for the sensing version you need the -S variant. The 33 mm adjustable air cushions only decelerate the piston near the ends, so fit an external rod lock or pilot-operated check valve if you must hold a load on 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 |
| 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 JSIJ100X400-10 Is Used
Press Stroke Trimming
Dial in the exact 390-400 mm extend position on a forming press without shimming or changing the cylinder, using the 10 mm external adjuster to set the precise crush depth.
Vertical Material Lift
Lower a 200 kg fixture in a vertical lift application, using the adjustable cushions to decelerate the load smoothly over the 400 mm travel before the fixed retract position.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X400-10 the Right Cylinder?
Size this 100 mm bore against the neighbouring 80 mm and 125 mm options. The 10 mm adjustable window is perfect for sharing a single spare across slightly different 400 mm stroke machines, letting you dial in the exact end position on-site. Mounting choices include Basic, FA, LB, TC, TCM1 and TCM2 brackets. Because this is a 400 mm stroke, always support the load with an external guide to prevent rod bending and premature seal wear from side loads.
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 JSIJ100X400-10 FAQ
This 100 mm bore cylinder uses a G1/2 port. It pushes 3927 N and pulls 3574 N at 0.5 MPa. At 0.7 MPa it pushes 5497 N and pulls 5003 N. The theoretical maximum force is 801 kgf at 1.0 MPa.
The -10 means the extend stroke can be shortened by up to 10 mm via an external stop screw. The nominal 400 mm stroke is the maximum, so your usable extend range is 390-400 mm. The retract end remains fixed, and this stop mechanism only sets position; it does not lock the load.
