Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X350-30S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X350-30S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 350mm 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 JSIJ100X350-30S
The extruded hard-anodized aluminium barrel omits tie rods entirely, making the overall body shorter and more compact than a same-bore ISO 15552 unit. A G1/2 port supplies the air, while adjustable 33 mm cushions absorb kinetic energy at both stroke ends.
The -30 code defines an external stop-screw window that lets you shorten the extend stroke on-site by up to 30 mm, dropping the usable forward travel from the 350 mm maximum down to 320 mm without changing the physical mount. This on-site end-position tuning is ideal for sharing spares across slightly different machine variants. The -S suffix adds a piston magnet for CMSE/DMSE switches.

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).

Where the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X350-30S Is Used
Press Fit Tuning
Fine-tune the 320 to 350 mm extend position on-site to set precise insertion depths for bearing presses without machining new stops.
Multi-Point Diversion
Use the external adjuster to alter a diverter arm endpoint by up to 30 mm, accommodating different package sizes on a single line.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X350-30S the Right Cylinder?
The 30 mm adjustable window shines on assembly lines where you need to fine-tune the extend endpoint without swapping the cylinder, letting one spare cover multiple stroke variants. JSIJ mounting options include Basic, FA, LB, TC, TCM1, and TCM2. Because the 350 mm stroke creates leverage, always support the load with an external guide to prevent rod bending and premature seal wear. The -S magnet enables direct CMSE/DMSE sensors 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 JSIJ100X350-30S FAQ
At 0.5 MPa this 100 mm bore cylinder pushes with 3927 N and pulls with 3574 N. At 0.7 MPa the push increases to 5497 N and the pull to 5003 N. The theoretical maximum force is 801 kgf at 1.0 MPa. It features a 32 mm rod, a G1/2 port, M26x1.5 rod thread, and 33 mm adjustable air cushions. Operating speed ranges from 30 to 800 mm/s.
The nominal 350 mm stroke is the maximum forward travel. The external adjuster lets you shorten the extend stroke on-site by up to 30 mm, providing a usable range of 320 to 350 mm. The retract end remains fixed. This mechanism sets the end position but does not lock the load; if air is lost, you need an external rod lock or pilot-operated check valve to hold position.
