Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X160-30
The AirTAC Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X160-30 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 JSIJ125X160-30
Delivering 6136 N of push force at 0.5 MPa, this 125 mm bore JIS profile cylinder is built for heavy-duty positioning. The extruded hard-anodized aluminium body is noticeably shorter than a same-bore ISO 15552 unit, saving valuable machine space without losing power. It handles about 3682 N of real work safely, which means lifting roughly 313 kg vertically with a 2:1 margin.
The -30 code means an external adjuster can shorten the extend stroke on-site by up to 30 mm, giving a usable range of 130-160 mm while the retract end stays fixed. This lets you fine-tune the end position without swapping the cylinder. The unit uses a G1/2 port, a 32 mm rod, and adjustable air cushions. Note that this specific SKU lacks a magnet, so it cannot take CMSE or DMSE sensors.

Where the Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X160-30 Is Used
Press Tonnage Trimming
Use the external adjuster to dial in the exact 130-160 mm extend reach for light stamping tasks, ensuring precise contact without re-mounting the actuator.
Heavy Pallet Stops
Leverage the 6136 N push force to halt heavy pallets on a conveyor, tweaking the stop position by up to 30 mm on-site to accommodate varying load depths.
Stamping Pin Depth Control
Set the extend stroke precisely for marking or pinning operations, using the adjustable window to fine-tune the downward travel limit on the production line.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X160-30 the Right Cylinder?
When sizing this model, compare it against the neighbouring 100 mm bore, which offers 3927 N of push at 0.5 MPa, and the 125 mm bore itself, which sits at the top edge with 6136 N. The adjustable stroke is ideal when you need to tune the extend end-position on-site or want a shared spare across slightly different stroke variants. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Because the 160 mm stroke is relatively short for this large bore, side-load risks are minimal, but for any stroke over 300 mm you should always use a guide rail to prevent piston binding. Without a magnet, this version cannot support position sensing.
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 JSIJ125X160-30 FAQ
At 0.5 MPa it provides 6136 N push and 5734 N pull. At 0.7 MPa it provides 8590 N push and 8028 N pull. The theoretical maximum force is 1251 kgf at 1.0 MPa. It features a 125 mm bore, a 32 mm rod, a G1/2 port, M27x2.0 rod thread, and 33 mm adjustable air cushions at both ends. The operating speed range is 30-500 mm/s.
The nominal stroke is 160 mm, which is the maximum extend travel. The external adjuster allows you to shorten the extend stroke on-site by up to 30 mm, giving a usable range of 130-160 mm. The retract end is fixed. This mechanism only sets the end position and does not lock the load; a plain cylinder will drift on air loss, so use an external rod lock or pilot-operated check valve if you need to hold a load.
