Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X80-50
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X80-50 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 JSIJ100X80-50
The hard-anodized aluminium barrel keeps the total length shorter than a comparable ISO 15552 unit, saving valuable machine space. A G1/2 port supplies air, while the 32 mm rod and M26x1.5 thread manage high thrust loads.
The external stop screw lets you shorten the extend stroke on-site by up to 50 mm, giving a usable range of 30 to 80 mm out of the 80 mm nominal maximum. You can fine-tune the end position without swapping the cylinder. Note this SKU lacks a magnet, so it cannot take CMSE or DMSE sensors.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|

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 JSIJ100X80-50 Is Used
Press Fit Dialing
Use the 50 mm extend adjuster to fine-tune a press-fit depth on-site without machining new spacers or changing the cylinder body.
Pallet Stopper Tuning
Set the exact 30 to 80 mm extend position to act as a heavy-duty stop for varying pallet sizes on a high-thrust conveyor line.
Shared Spare Inventory
Keep one 80 mm nominal unit as a universal spare, shortening the extend stroke on-site to cover several shorter standard stroke machines.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X80-50 the Right Cylinder?
The 50 mm adjuster window is ideal when you need to share one spare cylinder across several stroke variants or dial in a precise end position on the factory floor. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2. Because this plain cylinder has no magnet, you cannot mount position sensors; add the -S variant for CMSE or DMSE switches. For any stroke 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 JSIJ100X80-50 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, a 32 mm rod, and has a 33 mm adjustable air cushion at each end.
The 80 mm nominal stroke is the maximum. The external adjuster lets you shorten the extend stroke on-site by up to 50 mm, giving a usable extend range of 30 to 80 mm. The retract end is fixed. This mechanism sets the end position and is not a load lock; for load holding on air loss, use an external rod lock or pilot-operated check valve.
