Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X300-30S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X300-30S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 300mm 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 JSIJ100X300-30S
The hard-anodized aluminium extrusion keeps the total length shorter than a same-bore ISO 15552 unit.
An external stop screw lets you trim the extend stroke by up to 30 mm on site, giving a usable 270 to 300 mm end-position window without swapping the cylinder. The retract end remains fixed. This -S variant includes a piston magnet for CMSE/DMSE sensors in the side grooves, and the G1/2 port handles high flow for 30 to 800 mm/s speeds.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3525 N | 3525 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 JSIJ100X300-30S Is Used
Press Stroke Tuning
Dial in the exact 270 to 300 mm extend contact point on a light assembly press without machining new hard stops.
Divertor Arm Adjustment
Fine-tune the pusher reach on a heavy conveyor divertor to handle different pallet widths on the fly.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X300-30S the Right Cylinder?
The adjustable 30 mm extend window is ideal for fine-tuning end positions on site or keeping a shared spare across similar stroke variants. You can mount it via FA, LB, TC, TCM1, or TCM2 brackets. Because the stroke is 300 mm, always use an external guide rail to prevent rod bending under side loads. The -S magnet supports CMSE/DMSE switches for position confirmation.
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 JSIJ100X300-30S 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. This 100 mm bore cylinder uses a G1/2 port and features a 33 mm adjustable air cushion at each end.
The 300 mm nominal stroke is the maximum extend length. The external adjuster lets you shorten the extend stroke on site by up to 30 mm, giving a usable range of 270 to 300 mm. The retract end is fixed. This mechanism sets the end position and is not a load lock; you need an external rod lock or pilot-operated check valve to hold a load on air loss.
