Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X80-75
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X80-75 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 JSIJ100X80-75
Its extruded hard-anodized aluminium barrel omits tie rods entirely, making the body noticeably shorter and more compact than a same-bore ISO 15552 unit. The G1/2 port feeds the 32 mm piston rod to cycle at 30-800 mm/s.
The external stop screw provides a 75 mm adjustable window, letting you fine-tune the extend end position down from the 80 mm maximum to a 5 mm minimum without swapping the actuator. Note this SKU lacks a magnet, so it cannot take CMSE or DMSE sensors.

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 JSIJ100X80-75 Is Used
Press Fit Tuning
Dial in the exact 5 to 80 mm extend contact point for seating heavy bearings without reworking fixture heights.
Variable Transfer Stops
Adjust the retract stop on the fly to handle mixed product lengths on a single 100 mm bore actuator line.
Pallet End Positioning
Fine-tune the extend stroke within the 75 mm window to align large pallets precisely before stretch wrapping.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X80-75 the Right Cylinder?
Stepping down to an 80 mm bore drops the 0.5 MPa push to 2513 N, while a 125 mm bore raises it to 6136 N if you need deeper thrust reserves. The 75 mm adjuster shines when you need to synchronise multiple end stops across shared spare actuators or dial in a precise touchpoint on-site. You can mount it via FA, LB, TC, TCM1, or TCM2 brackets. Because this is a non-magnetised SKU, position sensing is unavailable. For any stroke over 300 mm, always guide the load to prevent rod side-load wear.
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 JSIJ100X80-75 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 is 801 kgf at 1.0 MPa. It uses a G1/2 air port and a 32 mm rod with an M26x1.5 thread.
The nominal 80 mm extend stroke is the maximum. An external stop screw lets you shorten that extend travel on-site by up to 75 mm, yielding a usable 5 to 80 mm range. The retract end is fixed. This mechanism sets the end position and is not a load lock.
