Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X75-40
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X75-40 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 JSIJ100X75-40
The hard-anodized aluminium extruded barrel houses a 32 mm piston rod with an M26x1.5 thread, while a G1/2 port supplies the air. An external adjuster lets you shorten the extend stroke on-site by up to 40 mm, meaning the usable forward travel spans 35 to 75 mm without swapping the cylinder.
The 33 mm adjustable air cushions at both ends absorb end-of-stroke impact, though the stop screw sets position rather than locking the load. Because this SKU lacks a -S magnet, it cannot accept CMSE or DMSE sensors; add the -S variant if you need position detection.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3525 N | 3525 N |
| 0.7 MPa | 4935 N | 4935 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 JSIJ100X75-40 Is Used
Press Fit Tuning
Dial in the exact 35 to 75 mm insertion depth for bearing presses on-site, using the 40 mm external adjuster to compensate for material thickness variations without changing cylinders.
Short-Stroke Forming
Execute compact metal-forming hits in tight JIS machinery footprints where an ISO 15552 cylinder would be too long, fine-tuning the impact depth via the stop screw.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X75-40 the Right Cylinder?
The 40 mm adjustable window is ideal for sharing a single spare across machines that need slightly different end positions, letting you fine-tune the 35 to 75 mm extend travel on the floor. You can mount it via basic, FA, LB, TC, TCM1, or TCM2 brackets. Since the 75 mm stroke is short, side-load risks are minimal, but any application over 300 mm requires a guide rail 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 JSIJ100X75-40 FAQ
At 0.5 MPa it pushes 3927 N and pulls 3574 N. At 0.7 MPa the push is 5497 N and pull is 5003 N. The theoretical maximum force is 801 kgf at 1.0 MPa. It uses a G1/2 air port.
The 75 mm nominal stroke is the maximum forward travel. The external adjuster lets you shorten the extend stroke by up to 40 mm on-site, giving a usable range of 35 to 75 mm. The retract end remains fixed. Note that this mechanism only sets the end position; it does not hold the load on air loss.
