Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X200-10
The AirTAC Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X200-10 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø125mm bore and 200mm 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 JSIJ125X200-10
Delivering 6136 N of push force at 0.5 MPa, this 125 mm bore JIS profile cylinder brings heavy-duty actuation into a compact footprint that is noticeably shorter than a same-bore ISO 15552 unit. The hard-anodized aluminium barrel keeps the assembly light, and the G1/2 port matches the high flow demands of this large bore.
The -10 code means an external adjuster can shorten the extend stroke by up to 10 mm on site, giving a usable 190-200 mm forward travel while the retract end stays fixed. This lets you fine-tune the end position without swapping the cylinder. Based on the 0.5 MPa push rating, it handles about 3682 N of real work, which translates to lifting roughly 313 kg vertically with a 2:1 safety margin.

Where the Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X200-10 Is Used
Heavy Pallet Forming
Tunes the final 10 mm of extend travel to press pallets together perfectly, accommodating material thickness variations without remounting the actuator.
Hydraulic Press Feed
Provides massive 6136 N push at 0.5 MPa to feed heavy blanks, with the external adjuster allowing quick length tweaks when blank sizes change.
Large Mold Clamping
Secures large injection molds with up to 1251 kgf at 1.0 MPa, using the 10 mm stroke window to dial in the exact clamping endpoint on-site.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X200-10 the Right Cylinder?
As the largest standard bore, this 125 mm model sits at the top edge of the range; if 8590 N at 0.7 MPa is excessive, step down to the 100 mm bore which still offers 5497 N push. The adjustable stroke is ideal for sharing a single spare across machines that need slightly different 190-200 mm end positions. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2. Because this SKU lacks the -S suffix, it cannot accept a magnetic sensor; order the -S variant for CMSE or DMSE switches. For any stroke over 300 mm, always use a guide rail to prevent side-load damage.
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 JSIJ125X200-10 FAQ
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. It uses a G1/2 port and runs at 30-500 mm/s.
The nominal 200 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 10 mm on site, giving a usable range of 190-200 mm for fine-tuning the end position. The retract end is fixed. This stop only sets position; it does not lock the load.
