Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X600-30
The AirTAC Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X600-30 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø125mm 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 JSIJ125X600-30
Delivering massive thrust in a compact JIS profile, this hard-anodized aluminum cylinder pushes with 6136 N at 0.5 MPa. It handles about 3682 N of safe working load, which means you can lift roughly 313 kg vertically with a 2:1 margin. The G1/2 port feeds the 32 mm rod to generate this power without needing bulky external rods.
The external adjuster lets you fine-tune the extend stroke on-site, shortening the 600 mm nominal travel by up to 30 mm for exact end-positioning. This unit is shorter than an ISO 15552 cylinder of the same bore. Because this SKU lacks a magnet, it cannot take a CMSE or DMSE sensor.

Where the Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X600-30 Is Used
Heavy Pallet Lifting
Raises heavy pallets in automated warehouses, using the 30 mm extend adjustment to fine-tune the exact raising height without reprogramming the PLC.
Press Ejection
Ejects dense metal parts from a press, relying on the 6136 N push force and the compact JIS profile to fit within tight machine footprints.
Stamping Positioning
Drives a large stamping head down to a precise depth, adjusting the 600 mm extend stroke on-site by up to 30 mm to account for die wear.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X600-30 the Right Cylinder?
At the top of the range, this 125 mm bore pushes 6136 N at 0.5 MPa; dropping to the 100 mm bore lowers that to 3927 N. The 30 mm adjustment window is perfect for sharing one spare across multiple stroke variants or dialing in final positioning. Mount using FA, LB, TC, TCM1, or TCM2 brackets. With a 600 mm stroke, always use external guides to prevent rod bending under side loads. Note that a plain cylinder drifts on air loss; use an external rod lock or pilot-operated check valve to hold a load.
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 JSIJ125X600-30 FAQ
It uses a G1/2 port. At 0.5 MPa it pushes 6136 N and pulls 5734 N. At 0.7 MPa it pushes 8590 N and pulls 8028 N. The theoretical maximum force is 1251 kgf at 1.0 MPa.
The 600 mm nominal stroke is the maximum travel. The external stop screw lets you shorten the extend stroke on-site by up to 30 mm, giving a usable range of 570-600 mm. The retract end remains fixed, and this mechanism only sets the end position; it does not lock the load.
