Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X600-40
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X600-40 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 600mm 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 JSIJ100X600-40
The extruded hard-anodized aluminum barrel omits tie rods entirely, leaving a smooth outer profile that is physically shorter and more compact than a same-bore ISO 15552 unit. It uses a G1/2 port and a 32 mm rod with an M26x1.5 thread.
The -40 code means an external adjuster can shorten the extend stroke on-site by up to 40 mm, giving a usable extend range of 560 to 600 mm while the retract end stays fixed. You can fine-tune the end position without swapping the cylinder, and the nominal 600 mm remains the maximum. Note this plain SKU lacks a magnet and cannot take CMSE/DMSE sensors.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3525 N | 3525 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 JSIJ100X600-40 Is Used
Conveyor Transfer Diverter
Pushes heavy pallets off a main belt, using the 40 mm adjuster to fine-tune the divert distance for varying box widths without changing hardware.
Vertical Material Lift
Raises a 200 kg payload between floor levels, relying on the adjustable cushion to decelerate the load smoothly at the top of the 600 mm stroke.
Press Clamping Stop
Extends to clamp large workpieces, where the on-site stroke adjustment allows precise positioning of the jaw against the part profile.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X600-40 the Right Cylinder?
The adjustable stroke is ideal when you need to tune the extend end-point on-site or want a single spare that covers minor stroke variations. JSIJ mounting choices include FA, LB, TC, TCM1, and TCM2. Because the 600 mm stroke is long, always support the load with external guides to prevent rod bending and side-load wear. Remember that a plain cylinder drifts on air loss; use 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 JSIJ100X600-40 FAQ
The theoretical maximum force is 801 kgf at 1.0 MPa. This 100 mm bore unit uses a G1/2 air port, a 32 mm rod, and has a 33 mm adjustable air cushion at each end.
The 600 mm stroke is the maximum extend length. An external stop screw lets you shorten the extend stroke on-site by up to 40 mm, giving a usable range of 560 to 600 mm. The retract end is fixed. This mechanism sets the end position but is not a load lock, so the cylinder will drift if air pressure is lost.
