Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X600-100SH
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ125X600-100SH is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø125mm 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 JSIJ125X600-100SH
The external stop screw lets you trim the extend stroke by up to 100 mm on site, meaning usable travel spans 500 to 600 mm while the retract end remains fixed. This mechanism allows fine-tuning the end position without swapping the actuator. Built to JIS standards, the extruded hard-anodized aluminum barrel is noticeably shorter and more compact than a same-bore ISO 15552 unit. The G1/2 port feeds the 32 mm rod, and a 33 mm adjustable air cushion decelerates the heavy payload at each end.
This specific SKU includes a piston magnet for CMSE/DMSE sensors and high-temperature Viton seals. A plain pneumatic actuator does not hold load on air loss; the cushion only decelerates near the end of travel, so fit an external rod lock or pilot-operated check valve if you need to suspend weight. Because the 600 mm stroke invites rod bending, always support the load with an external guide to prevent side-load damage.

Theoretical Output Force (Ø125mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 5734 N | 5734 N |
| 0.7 MPa | 8027 N | 8027 N |
| Max (@1.0 MPa) | 1169 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 JSIJ125X600-100SH Is Used
Heavy Press Tonnage
Use the 6136 N extend thrust to form heavy sheet metal, relying on the 100 mm stop-screw window to fine-tune the pressing depth precisely on site.
High-Temp Ejection
Deploy the Viton-sealed actuator near hot molding lines to eject dense parts, using the 33 mm cushions to soften the end-of-stroke impact.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X600-100SH the Right Cylinder?
The 100 mm adjustable window is ideal when you need to share one spare cylinder across several stroke variants or dial in a precise end position on the machine. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. The built-in magnet supports CMSE/DMSE switches for end-position sensing. For the 600 mm stroke, external guiding is mandatory to prevent rod bending under heavy loads.
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 JSIJ125X600-100SH FAQ
The theoretical maximum force is 1251 kgf at 1.0 MPa. It features a G1/2 port and a 32 mm rod.
The nominal 600 mm extend stroke is the maximum travel. An external stop screw lets you shorten the extend stroke by up to 100 mm on site, yielding a usable range of 500 to 600 mm. The retract end remains fixed, and this mechanism only sets the end position rather than locking the load.
