Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X800-50S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X800-50S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 800mm 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 JSIJ100X800-50S
The hard-anodized aluminum extruded barrel contains no external tie rods, and the G1/2 port handles the substantial air volume needed for high thrust. It carries an integrated piston magnet for CMSE/DMSE sensors.
The -50 code defines an external adjuster window that lets you shorten the extend stroke on site by up to 50 mm, giving a usable range of 750 to 800 mm while the retract end remains fixed. You can fine-tune the end position without physically remounting the actuator.

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 JSIJ100X800-50S Is Used
Press Stroke Tuning
Dial in the exact 750 to 800 mm extend contact point on a large assembly press without swapping the cylinder.
Pallet Positioning Stop
Adjust the end stop on the fly to accommodate different pallet depths in a high-thrust conveyor line.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X800-50S the Right Cylinder?
This 100 mm model sits in the heavy-duty middle, offering 5497 N at 0.7 MPa if you need extra thrust. The adjustable stroke is ideal when you need to tune the extend end position on-site or want a single spare part that covers minor stroke variations. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. The -S suffix means the side grooves accept CMSE/DMSE reed or electronic switches. Because the stroke is 800 mm, you must support the load with external guides to prevent rod bending and excessive side loading.
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 JSIJ100X800-50S FAQ
At 0.5 MPa it pushes 3927 N and pulls 3574 N. At 0.7 MPa it pushes 5497 N and pulls 5003 N. The theoretical maximum force is 801 kgf at 1.0 MPa. It uses a G1/2 port and a 32 mm rod.
The nominal 800 mm stroke is the maximum. The external adjuster lets you shorten the extend stroke by up to 50 mm on site, giving a usable range of 750 to 800 mm. The retract end is fixed. This mechanism sets the end position and does not lock the load.
