Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X500-30S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X500-30S 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 JSIJ100X500-30S
The -30 mm window lets you shorten the 500 mm nominal travel down to 470 mm without swapping the unit, while the retract end remains fixed.
Built with an extruded hard-anodized aluminium barrel, the body is noticeably shorter and more compact than a same-bore ISO 15552 cylinder. The G1/2 port feeds the 32 mm rod, and the -S suffix means a built-in magnet is present for CMSE/DMSE sensors that drop directly into the side grooves. The adjustable air cushions provide 33 mm of end-deceleration, though the cylinder relies on live air and will drift if pressure drops, so fit an external rod lock for held loads.

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 JSIJ100X500-30S Is Used
Divert Gate Tuning
Dial in the exact 470 to 500 mm extend reach on a sorting line to hit the diverter angle precisely without remounting the actuator.
Pallet Stopper Adjustment
Absorb impact and fine-tune the stopping face for mixed pallet sizes, using the 33 mm cushions to decelerate heavy 200 kg vertical loads.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X500-30S the Right Cylinder?
The adjustable stroke is ideal for sharing one spare across multiple stroke variants or dialing in exact end positions on-site. 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 side-load damage.
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 JSIJ100X500-30S FAQ
The theoretical maximum is 801 kgf at 1.0 MPa. This 100 mm bore unit uses a G1/2 port, a 32 mm rod, and M26x1.5 rod-end threads.
The external stop screw lets you shorten the extend stroke by up to 30 mm on-site, giving a usable extend range of 470 to 500 mm. The nominal 500 mm stroke is the maximum, and the retract end is fixed. This mechanism sets the end position but does not lock the load.
