Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X900-100
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X900-100 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 900mm 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 JSIJ100X900-100
The G1/2 port feeds the 32 mm rod to generate this thrust.
An external stop screw lets you trim the extend stroke on-site, shortening the 900 mm nominal travel by up to 100 mm for a usable 800-900 mm range without swapping the cylinder. The retract end remains fixed. Note this SKU lacks a magnet, so it cannot take CMSE or DMSE sensors, and the adjustable cushion only decelerates the load near stroke end rather than holding it if air drops.

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 JSIJ100X900-100 Is Used
Long-Transfer Diversion
Pushes heavy pallets off a main line, using the 100 mm adjuster to fine-tune the exact push distance for different box sizes on the fly.
Multi-Height Press Lowering
Lowers a 200 kg press head over a 900 mm travel, trimming the extend stop down to 800 mm when switching to shallower workpieces.
Adjustable Depth Stacking
Deposits parts into deep bins, relying on the external screw to shorten the extend stroke on-site as the stack height builds up.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X900-100 the Right Cylinder?
The 100 mm adjustable window is ideal for sharing one spare cylinder across several stroke variants or fine-tuning the end position during machine commissioning. You can mount it via FA, LB, TC, TCM1, or TCM2 brackets. Because the 900 mm stroke is long, always support the rod against side-load bending with an external guide. For position feedback you must select the -S magnet version for CMSE/DMSE switches, as this base SKU cannot accept them.
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 JSIJ100X900-100 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 maximum is 801 kgf at 1.0 MPa. It uses a G1/2 air port, a 32 mm rod, and has 33 mm adjustable air cushions at both ends.
The 900 mm nominal stroke is the maximum travel. The external adjuster lets you shorten the extend stroke on-site by up to 100 mm, giving a usable extend range of 800-900 mm. The retract end is fixed, and the adjuster sets the end position but does not lock the load.
