Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X125-50S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X125-50S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 125mm 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 JSIJ100X125-50S
The hard-anodized aluminum profile barrel keeps the body more compact than a same-bore ISO 15552 unit, and the G1/2 port feeds the 32 mm piston rod for high flow.
The external stop screw lets you shorten the extend stroke on-site by up to 50 mm, giving a usable range of 75 to 125 mm without changing the hardware. The -S suffix adds a piston magnet for CMSE/DMSE switches in the side grooves.

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 JSIJ100X125-50S Is Used
Press Fit Tuning
Dial in the exact 75 to 125 mm extend reach on-site to seat bearings without re-mounting the entire actuator.
Pallet Stop Adjustment
Shorten the extend stroke by 50 mm on the fly to accommodate varying pallet depths while maintaining high clamping force.
Diverter Gate Control
Use the magnetic switches and external adjuster to set precise diverting distances for mixed product lines.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X125-50S the Right Cylinder?
The adjustable window shines when you need to fine-tune end positions on-site or standardize a shared spare across multiple stroke variants. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Because this unit includes the -S magnet, it accepts CMSE/DMSE sensors. For any stroke at or above 300 mm, always use external guide rails to absorb side loads and prevent rod damage.
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 JSIJ100X125-50S FAQ
The theoretical maximum is 801 kgf at 1.0 MPa. It uses a G1/2 port and a 32 mm rod with an M26x1.5 thread.
The nominal 125 mm extend stroke is the maximum. An external stop screw lets you shorten the extend end position by up to 50 mm on-site, yielding a usable range of 75 to 125 mm. The retract end remains fixed. This mechanism sets the end position and does not lock the load.
