Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X275-100
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X275-100 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 275mm 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 JSIJ100X275-100
The hard-anodized aluminum extruded barrel makes it shorter than an equivalent ISO 15552 unit, saving valuable machine space.
The external stop screw provides a 100 mm adjustment window, letting you fine-tune the usable extend stroke down to 175 mm on site without swapping the cylinder. Air connects via a G1/2 port, and adjustable air cushions of 33 mm at each end manage end-of-stroke impact. This SKU lacks a magnet, so it cannot take CMSE or DMSE sensors; order the -S variant if you need position detection.

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 JSIJ100X275-100 Is Used
Press Fit Tuning
Use the 100 mm extend window to dial in the exact pressing depth of bearings on an assembly line without changing the physical cylinder length.
Variable Transfer Stop
Adjust the extend stroke on-site to act as a raised stop for different package sizes on a conveyor, accommodating varying product widths.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X275-100 the Right Cylinder?
The 100 mm adjuster window is highly useful when you need to share one spare cylinder across multiple stroke variants or fine-tune the end position during machine commissioning. You can mount it using the FA, LB, TC, TCM1, or TCM2 brackets. Because the 275 mm stroke exceeds 300 mm only slightly, side-load guidance is still recommended for the rod end to prevent premature wear. Remember that a plain cylinder drifts on air loss, so add an external rod lock or pilot-operated check valve if the load must be held.
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 JSIJ100X275-100 FAQ
The theoretical maximum force is 801 kgf at 1.0 MPa. It operates at speeds of 30-800 mm/s.
The nominal 275 mm stroke is the maximum length. The external adjuster lets you shorten the extend stroke by up to 100 mm on site, giving a usable extend range of 175-275 mm. The retract end remains fixed. This mechanism sets the end position and does not lock the load.
