Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X200-30S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X200-30S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 200mm 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 JSIJ100X200-30S
Its extruded hard-anodized aluminum barrel omits tie rods entirely, making the body noticeably shorter and more compact than a same-bore ISO 15552 unit. The G1/2 port handles the required air volume, while the integrated -S magnet allows direct mounting of CMSE or DMSE switches into the side grooves for precise end-of-stroke detection.
The -30 code means an external adjuster can shorten the extend stroke on-site by up to 30 mm, giving a usable forward travel range of 170 to 200 mm. You can fine-tune the end position without swapping the cylinder, and the retract end remains fixed. Note that the adjustable stop sets the end position but does not lock the load; a separate rod lock or pilot-operated check valve is needed to hold a load against air loss.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|

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).

Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X200-30S the Right Cylinder?
When sizing this 100 mm bore actuator, compare it against the 80 mm and 125 mm neighbors. The adjustable 170 to 200 mm extend window is highly useful when you want a single shared spare cylinder across multiple machines that have slightly different end-position requirements. JSIJ mounting options include Basic, FA, LB, TC, TCM1, and TCM2. The -S variant includes the piston magnet for CMSE/DMSE sensors; a non-S SKU cannot accept them. Because the 200 mm stroke is relatively short, side-load stress is minimal, but for any stroke length at or above 300 mm you should always guide the rod end to prevent binding.
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 JSIJ100X200-30S FAQ
At 0.7 MPa the push is 5497 N and the pull is 5003 N. The theoretical maximum force is 801 kgf at 1.0 MPa. The air port size is G1/2.
The nominal stroke is 200 mm, which is the maximum extend travel. The external adjuster lets you shorten the extend stroke on-site by up to 30 mm, giving a usable range of 170 to 200 mm. The retract end is fixed, and this mechanism only sets the end position; it does not lock the load.
