Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X75-30S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X75-30S 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 JSIJ100X75-30S
The hard-anodized aluminum barrel makes it shorter and more compact than a same-bore ISO 15552 unit. A G1/2 port feeds the 32 mm rod.
The external stop screw provides a 30 mm on-site extend-shortening window, letting you dial the usable forward stroke down from the 75 mm maximum to 45 mm without swapping the cylinder. Because this SKU carries the -S suffix, a built-in piston magnet is present, allowing CMSE or DMSE switches to drop directly into the side sensor grooves.

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 JSIJ100X75-30S Is Used
Press Fit Tuning
Dial in the exact 45 to 75 mm extend contact point for seating bearings without remounting the actuator.
Variable Transfer Stops
Adjust the stop finger position on-site by up to 30 mm to handle mixed product sizes on a single line.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X75-30S the Right Cylinder?
This 100 mm model is ideal when you need precise on-site end-position tuning across shared spare parts. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. The -S magnet enables position feedback. For any stroke length at or above 300 mm, always use external guide rails 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 JSIJ100X75-30S 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 max is 801 kgf at 1.0 MPa. It uses a G1/2 port.
The nominal 75 mm extend stroke is the maximum. An external stop screw lets you shorten the forward stroke by up to 30 mm on-site, giving a usable extend range of 45 to 75 mm. The retract end remains fixed. This mechanism sets end position and is not a load lock.
