Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X75-30
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X75-30 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 JSIJ100X75-30
An external stop screw provides a 30 mm adjustment window, letting you shorten the extend stroke from the 75 mm maximum down to 45 mm without swapping the actuator. The retract end remains fixed. Because the extruded hard-anodized aluminium barrel uses an integrated profile design, the overall body is shorter and more compact than a same-bore ISO 15552 cylinder, saving valuable machine footprint.
It uses a G1/2 port, a 32 mm piston rod, and 33 mm adjustable air cushions at both ends to decelerate the payload smoothly. Note that this specific SKU lacks a magnet and cannot accept CMSE or DMSE sensors; you would need the -S variant for position detection. Furthermore, the cushion only decelerates the load near the stroke end, so an external rod lock or pilot-operated check valve is required if you need to hold a load securely on air loss.

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 JSIJ100X75-30 Is Used
Press Clamping Tuning
Allows operators to dial in the exact 45 to 75 mm clamping reach on a machining fixture without machining new spacers or changing the cylinder.
Variable Height Stops
Ideal for heavy press operations where the bottoming position must be adjusted on-site by up to 30 mm to accommodate different material thicknesses.
Compact Diverting
Delivers high push force in a tight JIS profile envelope, fitting neatly between conveyor belts to deflect heavy pallets at a customized extend point.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X75-30 the Right Cylinder?
When sizing this 100 mm bore actuator, compare it against the neighbouring 80 mm and 125 mm options. The adjustable stroke is particularly useful when you want to standardize a shared spare across multiple stroke variants or fine-tune the end position during machine commissioning. Mounting choices for the JSIJ series include Basic, FA, LB, TC, TCM1, and TCM2. Because this is a no-magnet SKU, it cannot take a sensor; add the -S suffix if your control system requires CMSE or DMSE detection. For any application with a stroke of 300 mm or more, always guide the load externally to prevent excessive side-load wear on the piston rod and seals.
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 JSIJ100X75-30 FAQ
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 features a 100 mm bore, a 32 mm rod, a G1/2 port, an M26x1.5 rod thread, and 33 mm adjustable cushions at both ends.
The nominal stroke is 75 mm, which is the maximum extend length. The external adjuster lets you shorten the extend stroke on-site by up to 30 mm, giving a usable extend range of 45 to 75 mm. The retract end position is fixed, and the adjuster sets the end position rather than acting as a load lock.
