Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X100-40S
The AirTAC JSIJ32~50 Adjustable Cylinder JSIJ32X100-40S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø32mm bore and 100mm stroke, G1/8 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 JSIJ32~50 Adjustable Cylinder JSIJ32X100-40S
The integrated -S magnet allows CMSE/DMSE sensors to drop directly into the side grooves for precise position detection. A G1/8 port supplies the air, and the adjustable air cushions provide 20 mm of deceleration at each end.
The external adjuster lets you shorten the extend stroke on-site by up to 40 mm, meaning the usable forward travel spans 60-100 mm while the retract end remains fixed. The nominal 100 mm stroke is the absolute maximum, and the stop screw sets the end position rather than locking the load.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | 484 N |
| Max (@1.0 MPa) | 70 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 JSIJ32~50 Adjustable Cylinder JSIJ32X100-40S Is Used
Probe Positioning
Dial in the exact 60-100 mm extend reach for a testing probe on-site using the external adjuster, ensuring the sensor magnet registers correctly without remounting hardware.
Light Clamping
Apply up to 241 N of safe working force to hold delicate electronic components, tweaking the forward end position by up to 40 mm to accommodate varying part thicknesses.
Transfer Diverter
Actuate a small routing gate on a packaging line, relying on the compact JIS profile to save axial space while the 20 mm cushions absorb the impact at stroke end.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X100-40S the Right Cylinder?
Conversely, if 402 N is excessive, there is no smaller standard JSIJ bore, making this the baseline choice. The adjustable stroke is highly useful when you need to fine-tune the extend end position without swapping the cylinder, or when you want a single spare part to cover several stroke variants. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. The included -S magnet supports reed or electronic switches. For any stroke at or above 300 mm, always use a guide rail to prevent side-load damage to the piston rod.
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 JSIJ32~50 Adjustable Cylinder JSIJ32X100-40S FAQ
The theoretical maximum force is 82 kgf at 1.0 MPa.
The external stop screw lets you shorten the extend stroke on-site by up to 40 mm, giving a usable forward travel of 60-100 mm. The nominal 100 mm stroke is the maximum, and the retract end is fixed. This mechanism sets the end position and does not hold the load on air loss.
