Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X75-40S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X75-40S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 75mm 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 JSIJ100X75-40S
The nominal 75 mm stroke acts as the maximum, yielding a usable extend range of 35 to 75 mm while the retract end stays fixed. This built-in flexibility lets you fine-tune the end position without physically swapping the cylinder. The hard-anodized aluminum profile barrel keeps the total envelope more compact than a same-bore ISO 15552 unit. Air connections use a G1/2 port, and the integrated piston magnet supports CMSE/DMSE sensors.
Because the -S option is present, reed or electronic switches drop directly into the side grooves for precise position feedback. The adjustable 33 mm air cushions at both ends absorb kinetic energy near the stroke limits, but they only decelerate the piston and do not hold the load. If your application requires vertical load holding on air loss, you must add an external rod lock or a pilot-operated check valve, as a standard cylinder will drift when valve-centered. Operating pressure spans 0.15 to 1.0 MPa, with a proof pressure of 1.5 MPa across a -20 to +70 C temperature range.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3525 N | 3525 N |

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 JSIJ100X75-40S Is Used
Press Fit Tuning
Dial in the exact 35 to 75 mm extend position on-site to seat bearings without changing the physical cylinder setup.
Divertor Arm Adjustment
Fine-tune the extend stop in real time to accommodate different package sizes on a shared sorting line.
Pallet Stop Gate
Absorb heavy pallet impacts using the 33 mm cushions while adjusting the gate reach up to 40 mm for various pallet depths.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X75-40S the Right Cylinder?
When sizing this 100 mm bore unit, step down to an 80 mm cylinder if your force requirement drops below 2513 N at 0.5 MPa, or step up to a 125 mm bore for loads exceeding 3927 N. The 40 mm adjustable window is ideal for machines that share a common spare across slightly different stroke variants, letting maintenance teams dial in the exact extend end position on-site. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. The included -S magnet enables CMSE/DMSE sensor integration. For any stroke length at or above 300 mm, always use external guide rails to prevent side-load damage to the 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 JSIJ100X75-40S FAQ
At 0.7 MPa the push increases to 5497 N and the pull to 5003 N. The theoretical maximum force is 801 kgf at 1.0 MPa. It uses a G1/2 port and an M26x1.5 rod thread.
The external stop screw shortens the extend stroke by up to 40 mm on site. With a 75 mm nominal stroke acting as the maximum, your usable extend range is 35 to 75 mm. The retract end remains fixed, and the stop sets the end position rather than locking the load.
