Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X500-100
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X500-100 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 JSIJ100X500-100
The extruded hard-anodized aluminium barrel leaves out external tie rods, making the overall body shorter than a same-bore ISO 15552 unit. A G1/2 port feeds the chamber, while adjustable air cushions of 33 mm at each end absorb kinetic energy.
The external stop screw provides a 100 mm window to shorten the extend stroke on site, letting you fine-tune the end position anywhere from 400 to 500 mm without swapping the cylinder. Note this plain SKU lacks a magnet and cannot take a CMSE or DMSE sensor.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3525 N | 3525 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 JSIJ100X500-100 Is Used
Press Tonnage Calibration
Dial in the exact 400 to 500 mm extend contact point on-site via the external stop screw to set precise pressing depth without re-mounting the actuator.
Heavy Divertor Arms
Fine-tune the divertor reach by up to 100 mm during commissioning, ensuring positive product transfer without over-travel on the line.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X500-100 the Right Cylinder?
The 100 mm bore sits in the heavy-duty class, and its on-site adjustability is ideal when you need a shared spare across slightly different stroke variants. You can mount it via FA, LB, TC, TCM1, or TCM2 brackets. Because the stroke is 500 mm, always use an external guide to prevent rod bending under side loads. For position feedback, you must select the -S magnet version, as this base model cannot accept a sensor.
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 JSIJ100X500-100 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. It uses a G1/2 air port, a 32 mm rod, and 33 mm adjustable cushions at both ends.
The nominal 500 mm stroke is the maximum extend length. An external stop screw lets you shorten the extend stroke by up to 100 mm on site, giving a usable extend range of 400 to 500 mm. The retract end is fixed. This stop sets the end position and does not lock the load; for load holding on air loss, use an external rod lock or pilot-operated check valve.
