Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X80-30
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X80-30 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 JSIJ100X80-30
The extruded hard-anodized aluminium barrel keeps the overall body shorter and more compact than a same-bore ISO 15552 unit. Air connects via a G1/2 port, driving a 32 mm rod with M26x1.5 end threads and 33 mm adjustable cushions at each end.
The external adjuster allows you to shorten the extend stroke on-site by up to 30 mm, giving a usable forward travel of 50-80 mm without swapping the cylinder. Note this SKU lacks a magnet and cannot take a CMSE/DMSE sensor; for the -S variant if you need position feedback.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3525 N | 3525 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 JSIJ100X80-30 Is Used
Press Fit Tuning
Dial in the exact 50-80 mm insertion depth for bearing presses on-site using the 30 mm external adjuster, avoiding part damage without changing the cylinder.
Divertor Gate Stroke
Fine-tune the actuation reach on heavy sorting lines where the nominal 80 mm stroke needs a precise 5 mm trim to match varying package widths.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X80-30 the Right Cylinder?
The 30 mm adjuster is ideal for sharing one spare across multiple stroke variants or fine-tuning the end position during machine commissioning. Mounting options include FA, LB, TC, TCM1, and TCM2. Because this is a no-magnet SKU, it cannot host sensors. For any stroke length over 300 mm, always use a guide rail to prevent side-load 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 JSIJ100X80-30 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 operates at 30-800 mm/s.
The nominal 80 mm stroke is the maximum forward travel. An external stop screw lets you shorten the extend stroke on-site by up to 30 mm, yielding a usable range of 50-80 mm. The retract end is fixed. This mechanism sets the end position and is not a load lock.
