Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X350-50S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X350-50S 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 JSIJ100X350-50S
The hard-anodized aluminum extruded barrel contains no external tie rods, and the G1/2 port handles the air volume needed for robust thrust. A built-in piston magnet (-S) allows CMSE or DMSE switches to drop directly into the side sensor grooves.
The -50 code defines an external adjuster that shortens the on-site extend stroke by up to 50 mm, giving a usable forward travel of 300 to 350 mm while the retract end remains fixed. This lets you fine-tune the end position without swapping the cylinder. Note that a plain cylinder drifts on air loss, as the adjustable cushion only decelerates; use 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 JSIJ100X350-50S Is Used
Press Fit Tuning
Dial in the exact 300 to 350 mm extend reach for seating heavy bearings without remounting the entire actuator.
Multi-Length Diverting
Use the 50 mm adjuster window to alter the divert stroke for different package sizes on a shared conveyor line.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X350-50S the Right Cylinder?
The 50 mm adjustable window is ideal for sharing a single spare across multiple stroke variants or dialing in final end positions on-site. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. The -S variant supports CMSE/DMSE sensors. Because the 350 mm stroke creates leverage, always support the rod against side-load bending with an external guide.
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 JSIJ100X350-50S FAQ
The theoretical maximum force is 801 kgf at 1.0 MPa. It uses a G1/2 port and a 33 mm adjustable air cushion at each end.
The nominal 350 mm stroke is the maximum travel. The external adjuster lets you shorten the extend stroke on-site by up to 50 mm, yielding a usable range of 300 to 350 mm. The retract end is fixed, and this mechanism sets the end position rather than locking the load.
