Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X150-10
The AirTAC Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X150-10 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø125mm bore and 150mm 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 JSIJ125X150-10
Delivering 6136 N of push force at 0.5 MPa, this 125 mm bore JIS profile cylinder brings heavy-duty motion into a footprint noticeably shorter than a same-bore ISO 15552 unit. The hard-anodized aluminum barrel keeps weight down while handling up to 1251 kgf at 1.0 MPa. It connects via a G1/2 port and runs at 30-500 mm/s.
The -10 code means an external adjuster can shorten the extend stroke on-site by up to 10 mm, letting you fine-tune the end position from 140 to 150 mm without swapping the cylinder. This design handles about 3682 N of real work safely, roughly 313 kg lifted vertically. Note that this specific SKU lacks a magnet and cannot take a CMSE or DMSE sensor.

Where the Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X150-10 Is Used
Heavy Pallet Forming
Use the 10 mm extend window to dial in the exact compaction distance for varying pallet heights without reprogramming the machine.
Press Fit Tuning
Achieve precise bearing insertion stops on-site by shortening the 150 mm stroke up to 10 mm to avoid bottoming out.
Large Door Actuation
Move heavy industrial doors with 6136 N of thrust while trimming the final closed position by millimeters for a tighter seal.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X150-10 the Right Cylinder?
For lighter jobs, the 100 mm bore provides 3927 N push at 0.5 MPa, while this 125 mm bore hits 6136 N at 0.5 MPa and 8590 N at 0.7 MPa, marking the top edge of the range. The 10 mm adjuster is perfect for sharing a spare across slight stroke variants or final end-position tuning. Mounting options include FA, LB, TC, TCM1, and TCM2. You must add external guiding for any side loads, especially as strokes approach 300 mm or more.
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 JSIJ125X150-10 FAQ
It pushes 6136 N and pulls 5734 N at 0.5 MPa. At 0.7 MPa it pushes 8590 N and pulls 8028 N. The theoretical maximum force is 1251 kgf at 1.0 MPa.
An external stop screw lets you shorten the extend stroke on-site by up to 10 mm, giving a usable range of 140 to 150 mm. The nominal 150 mm stroke is the maximum, and the retract end stays fixed.
