Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X100-10S
The AirTAC Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X100-10S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø125mm bore and 100mm 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 JSIJ125X100-10S
Delivering 6136 N of push force at 0.5 MPa, this 125 mm bore JIS profile cylinder handles heavy automation tasks with ease. The hard-anodized aluminium barrel keeps the body shorter and more compact than a same-bore ISO 15552 unit. A built-in magnet (-S) lets you drop CMSE or DMSE switches directly into the side grooves for precise position detection. It connects via a G1/2 port and runs at 30-500 mm/s.
The -10 code means an external stop screw lets you shorten the extend stroke on-site by up to 10 mm, giving a usable 90-100 mm range while the retract end stays fixed. You can fine-tune the end position without swapping the cylinder, which is ideal for shared spares across stroke variants. Based on the 0.5 MPa push rating, it handles a safe working load of roughly 3682 N, or about 313 kg lifted vertically with a 2:1 margin. Note that the adjustable stop sets position only; a plain cylinder drifts on air loss, so use an external rod lock or pilot-operated check valve to hold a suspended load.

Where the Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X100-10S Is Used
Heavy Pallet Lifts
Lifts loaded pallets vertically, using the 10 mm extend window to dial in the exact stop height without reprogramming the motion controller.
Press Fit Tuning
Presses heavy bearings into housings, relying on the external adjuster to fine-tune the final 90-100 mm extend position for perfect insertion depth.
Stamping Stopper
Acts as a heavy-duty end stop for large sheet metal feed lines, adjusting the extend stroke on-site to accommodate different material widths quickly.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X100-10S the Right Cylinder?
Size this 125 mm bore against the 100 mm option, which offers 3927 N push at 0.5 MPa, or step up if you need the absolute maximum 1251 kgf at 1.0 MPa. The 10 mm adjustable window shines when you need on-site end-position tuning across machines sharing a common spare. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. The -S suffix ensures you have the magnet required for CMSE/DMSE sensors. Because the stroke is 100 mm, standard guiding handles side loads fine, but always add a linear guide for any stroke reaching 300 mm or more to prevent rod binding.
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 JSIJ125X100-10S FAQ
It provides 6136 N push and 5734 N pull at 0.5 MPa, 8590 N push and 8028 N pull at 0.7 MPa, with a theoretical max of 1251 kgf at 1.0 MPa. The air port is G1/2.
The external stop screw lets you shorten the extend stroke by up to 10 mm on-site, giving a usable range of 90-100 mm from the 100 mm nominal maximum. The retract end remains fixed. This mechanism sets the end position and does not lock the load.
