Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X80-20S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X80-20S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 80mm 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 JSIJ100X80-20S
The hard-anodized aluminum extruded barrel sheds weight without sacrificing rigidity. Pneumatic connections use a G1/2 port.
The JSIJ100X80-20S uses an external stop screw to shorten the extend stroke on site by up to 20 mm, giving a usable forward range of 60-80 mm while the retract end remains fixed. You can fine-tune the end position without remounting the cylinder. Because this SKU includes the -S magnet, it accepts CMSE or DMSE electronic and reed switches directly in the side grooves. Remember that the adjustable stop and air cushions only decelerate the load; use an external rod lock or pilot-operated check valve if you need to hold a load on air loss.

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 JSIJ100X80-20S Is Used
Press Fit Tuning
Micro-adjust the 60-80 mm extend stroke on-site to set precise bearing insertion depth without reprogramming machine stops.
Vertical Lift Dampener
Lower 200 kg loads safely and use the adjustable end-position to dial in the exact resting height for different fixtures.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X80-20S the Right Cylinder?
When sizing this 100 mm bore model, stepping down to an 80 mm bore drops the 0.5 MPa push force to 2513 N, while stepping up to 125 mm raises it to 6136 N. The adjustable 20 mm window is ideal when you need to share one spare cylinder across several stroke variants or fine-tune the end position on-site without swapping the actuator. JSIJ mounting choices cover Basic, FA, LB, TC, TCM1, and TCM2. The integrated -S magnet supports CMSE/DMSE sensors. For any stroke length of 300 mm or more, always use a guide rail to prevent excessive side-loading on the 32 mm 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 JSIJ100~125 Adjustable Cylinder JSIJ100X80-20S FAQ
The theoretical maximum force is 801 kgf at 1.0 MPa. This 100 mm bore unit uses a G1/2 port and features a 32 mm rod with an M26x1.5 thread.
The nominal 80 mm stroke is the maximum extend length. The external adjuster lets you shorten the forward stroke by up to 20 mm on site, yielding a usable extend range of 60-80 mm. The retract end is fixed. This mechanism sets the end position and decelerates the load, but it is not a load lock.
