Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X500-40S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X500-40S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 500mm 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 JSIJ100X500-40S
Its extruded hard-anodized aluminium barrel is noticeably shorter and more compact than a same-bore ISO 15552 unit. The G1/2 port handles the high air volume needed for rapid cycling, while the M26x1.5 rod thread secures your tooling.
The external stop screw lets you trim the extend stroke on-site by up to 40 mm, giving a usable range of 460 to 500 mm without swapping the cylinder. The built-in -S magnet allows CMSE/DMSE switches to drop into the side grooves for precise position sensing.

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 JSIJ100X500-40S Is Used
Press Tooling Alignment
Fine-tune the 460 to 500 mm extend position on-site to perfectly seat heavy press tooling, compensating for mechanical stack-up without machining new spacers.
Pallet Divert Stroke
Adjust the extend reach on the fly to handle different pallet widths on a shared line, using the 100 mm bore to push 200 kg loads vertically or laterally.
Multi-Size Case Loading
Dial in the extend stop to accommodate varying package depths on a packing line, relying on the compact JIS profile to save valuable machine footprint.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X500-40S the Right Cylinder?
The 100 mm bore hits a sweet spot for mid-heavy automation. The 40 mm adjustable window is ideal for fine-tuning end positions on-site or sharing a single spare across multiple stroke variants. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2. Because the 500 mm stroke is long, always support the load with external guides 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 JSIJ100X500-40S FAQ
The theoretical maximum is 801 kgf at 1.0 MPa. The air port is G1/2.
An external stop screw shortens the extend stroke by up to 40 mm on-site, yielding a usable range of 460 to 500 mm. The nominal 500 mm stroke is the maximum, and the retract end remains fixed. This mechanism sets the end position and is not a load lock.
