Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X1000-50
The AirTAC Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X1000-50 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø125mm bore and 1000mm 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 JSIJ125X1000-50
Delivering massive thrust with a 125 mm bore, this double-acting single-rod profile cylinder pushes 6136 N and pulls 5734 N at 0.5 MPa. The hard-anodized aluminium barrel keeps the build more compact than a same-bore ISO 15552 unit, and the G1/2 port feeds the 32 mm rod for heavy-duty cycles.
The external stop screw lets you trim the extend stroke by up to 50 mm on site, giving a usable 950-1000 mm range while the retract end stays fixed. It handles about 3682 N of real work safely, lifting roughly 313 kg vertically with a 2:1 margin. Note this SKU lacks a magnet and cannot take CMSE/DMSE sensors, and plain air cushions only decelerate, so fit an external rod lock to hold loads.

Where the Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X1000-50 Is Used
Heavy Pallet Lift
Raises large loaded pallets, using the 50 mm extend trim to dial in the exact upper stop without repositioning the mount.
Press Ejection
Clears heavy stamped parts from a die, relying on the 6136 N push force and adjustable 33 mm cushions to soften the end impact.
Bulk Door Actuation
Opens large industrial warehouse doors, fine-tuning the 950-1000 mm opening window on site to clear overhead cranes.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X1000-50 the Right Cylinder?
At the top of the range, this 125 mm bore pushes 6136 N at 0.5 MPa, so step down to an 80 mm bore if your cycle only needs 2513 N. The 50 mm adjuster is perfect for sharing one spare across slightly different 950-1000 mm end positions. Use FA, LB, or TC mounts, and because the stroke is 1000 mm, always support the rod with external guides to prevent bending. You cannot fit sensors on this no-magnet version; choose an -S variant for CMSE/DMSE switches.
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 JSIJ125X1000-50 FAQ
It pushes 6136 N and pulls 5734 N at 0.5 MPa, pushes 8590 N and pulls 8028 N at 0.7 MPa, with a theoretical max of 1251 kgf at 1.0 MPa. The air port is G1/2.
An external stop screw shortens the extend stroke by up to 50 mm on site, giving a usable 950-1000 mm range. The nominal 1000 mm stroke is the maximum, and the retract end remains fixed.
