Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X600-20S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X600-20S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 600mm 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 JSIJ100X600-20S
The hard-anodized aluminum extruded barrel keeps the assembly light without external support rods.
The -20 code means an external adjuster can shorten the 600 mm extend stroke by up to 20 mm on site, yielding a usable 580-600 mm range for fine-tuning the end position without swapping the cylinder. Air connects via a G1/2 port, and the -S suffix adds a built-in piston magnet for CMSE/DMSE sensors in the side grooves. Adjustable 33 mm cushions decelerate the load at both ends, though a plain cylinder drifts on air loss and needs an external rod lock to hold a load securely.

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 JSIJ100X600-20S Is Used
Press Tooling Alignment
Fine-tune the 600 mm extend position by up to 20 mm on-site to perfectly seat heavy press tooling without machining new spacers.
Heavy Product Divert
Divert heavy manufactured goods on a conveyor line, relying on the 33 mm cushions to safely decelerate the 600 mm stroke.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X600-20S the Right Cylinder?
The 20 mm adjustable window is ideal for sharing one spare across multiple stroke variants or dialing in final positioning on-site. JSIJ supports Basic, FA, LB, TC, TCM1, and TCM2 mounts. Because this is a 600 mm stroke, always use an external guide to prevent rod bending and side loads. The -S magnet enables CMSE/DMSE switches 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 JSIJ100X600-20S 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 is 801 kgf at 1.0 MPa. It uses a G1/2 port and a 33 mm adjustable cushion at each end.
The 600 mm nominal stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 20 mm on-site, giving a usable range of 580-600 mm. The retract end remains fixed, and this mechanism sets end position rather than locking the load.
