Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X500-40
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X500-40 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 JSIJ100X500-40
Air connects via a G1/2 port.
The external adjuster lets you shorten the extend stroke on-site by up to 40 mm, giving a usable range of 460-500 mm without changing the cylinder itself. The retract end remains fixed, and the adjustable air cushions provide 33 mm of deceleration at each end. Because this SKU lacks a magnet, it cannot take a CMSE or DMSE sensor; for position feedback you would need the -S variant.

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 JSIJ100X500-40 Is Used
Press Fit Tuning
Fine-tune the 460-500 mm extend position on-site to set precise pressing depth for bearings without machining custom spacers.
Multi-Length Diverting
Adjust the extend stroke by up to 40 mm to handle different carton sizes on a single packaging line using one cylinder.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X500-40 the Right Cylinder?
The -40 mm adjuster is ideal for sharing one spare cylinder across multiple stroke variants or fine-tuning the end position during machine commissioning. Mounting options include FA, LB, TC, TCM1, and TCM2. Since the 500 mm stroke is long, always use an external guide to prevent rod bending and side loads. Remember that the cushions only decelerate the piston; use an external rod lock or pilot-operated check valve if the load must be held on air loss.
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 JSIJ100X500-40 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. The air port is G1/2.
An external stop screw lets you shorten the extend stroke on-site by up to 40 mm. The usable extend range is 460-500 mm, with 500 mm being the maximum. The retract end is fixed, and this stop is for positioning only, not for holding a load.
