Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X160-100S
The AirTAC Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X160-100S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø125mm bore and 160mm 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 JSIJ125X160-100S
Delivering 6136 N of push force at 0.5 MPa, this 125 mm bore JIS profile cylinder features an external adjuster that shortens the extend stroke on-site by up to 100 mm. The nominal 160 mm stroke remains the maximum travel, letting you fine-tune the end position without swapping the actuator. Its hard-anodized aluminium extruded barrel keeps the total length shorter than a same-bore ISO 15552 unit. A built-in magnet (-S) supports CMSE and DMSE sensors that drop directly into the side grooves.
Equipped with a G1/2 port and an M27x2.0 rod thread, the unit handles a safe working load of about 3682 N, which translates to roughly 313 kg lifted vertically with a 2:1 margin. The 33 mm adjustable air cushions at both ends absorb impact, but remember the cushion only decelerates the piston. To hold a load securely on air loss, fit an external rod lock or a pilot-operated check valve, as the cylinder itself will drift.

Where the Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X160-100S Is Used
Heavy Pallet Lift
Raises loaded pallets in a packaging line, using the 100 mm adjuster to tweak the exact lift height for different box sizes without changing the cylinder.
Press Tonnage Stop
Acts as a heavy-duty end-stop in an assembly press, relying on 6136 N of thrust at 0.5 MPa and dialing in the precise 60 to 160 mm extend position on-site.
Divertor Gate Control
Drives a heavy diverter arm on a sorting conveyor, using the built-in magnet and DMSE sensors to confirm gate position across the adjusted stroke.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X160-100S the Right Cylinder?
When sizing this actuator, compare it against the neighbouring 100 mm bore, which provides 3927 N of push at 0.5 MPa, and decide if you need the 6136 N thrust this larger bore offers. The 125 mm bore sits at the top of the range, delivering a maximum theoretical force of 1251 kgf at 1.0 MPa. The 100 mm adjustable window is ideal for sharing a single spare across multiple stroke variants or dialling in exact end positions on-site. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. The -S magnet enables position sensing with CMSE or DMSE switches. Because the 160 mm stroke is relatively short, side-load stress is minimal, but for any application exceeding 300 mm of travel, always use external guide rails 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 JSIJ125X160-100S FAQ
This 125 mm bore cylinder uses a G1/2 port. It generates 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 maximum force of 1251 kgf at 1.0 MPa.
The external adjuster lets you shorten the extend stroke by up to 100 mm on-site, giving a usable extend range of 60 to 160 mm. The nominal 160 mm stroke is the maximum travel, and the retract end remains fixed.
