Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X80-40S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X80-40S 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 JSIJ100X80-40S
The hard-anodized aluminum barrel keeps the assembly light without external support rods.
The -40 code means an external adjuster can shorten the 80 mm extend stroke on site by up to 40 mm, giving a usable extend range of 40-80 mm for fine-tuning the end position without swapping the cylinder. The retract end remains fixed. Air connects via a G1/2 port, and the -S suffix adds a built-in piston magnet for CMSE/DMSE sensors that drop directly into the side grooves. Adjustable air cushions of 33 mm at each end absorb shock, though the cylinder relies on live air and will drift if pressure drops unless you add an external rod lock.

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 JSIJ100X80-40S Is Used
Press Fit Tuning
Dial in the exact 40-80 mm extend position for seating bearings without machining custom spacers or changing the actuator body.
Variable Transfer Stop
Adjust the extend stop on-site to handle different package widths on a packing line, using the 100 mm bore to absorb heavy impacts.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X80-40S the Right Cylinder?
When sizing this 100 mm bore, stepping down to an 80 mm unit drops the 0.5 MPa push force to 2513 N, while stepping up to 125 mm raises it to 6136 N. The adjustable stroke shines when you need to dial in a precise end position on the machine or want a single shared spare for multiple stroke variants. Mounting options include FA, LB, TC, TCM1, and TCM2. The -S magnet enables position feedback. Because the 80 mm stroke is relatively short, side-load stress is minimal, but for any application exceeding 300 mm of travel, always guide the load to prevent rod binding.
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 JSIJ100X80-40S 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. The air port size is G1/2.
The nominal 80 mm stroke is the maximum. The external adjuster lets you shorten the extend stroke by up to 40 mm on site, yielding a usable extend range of 40-80 mm. The retract end is fixed, and the adjuster sets the end position rather than locking the load.
