Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X100-100
The AirTAC Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X100-100 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 100mm 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 JSIJ100X100-100
Delivering 3927 N of push force at 0.5 MPa, this 100 mm bore JIS profile cylinder packs serious power into a body notably shorter than a same-size ISO 15552 unit. The hard-anodized aluminium barrel keeps the assembly light, while the G1/2 port handles the air volume this bore demands. It handles about 2356 N of real work safely, which means you can lift roughly 200 kg vertically with a 2:1 margin.
The -100 code means an external adjuster can shorten the extend stroke by up to 100 mm on-site, letting you fine-tune the end position without swapping the cylinder. The retract end stays fixed, and the adjustable air cushions provide 33 mm of deceleration at each end. Note this plain SKU lacks a magnet and cannot take a CMSE or DMSE sensor; for that you need the -S variant.

Where the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X100-100 Is Used
Press Fit Tuning
Dial in the exact 10 to 100 mm extend contact point for pressing bearings without machining new hard stops.
Variable Length Diverter
Adjust the extend stroke on-site to deflect different package sizes on a packaging line.
Shared Spare Cylinder
Keep one cylinder in stock and set the external stop screw to cover any extend length up to 100 mm.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X100-100 the Right Cylinder?
When sizing, the 80 mm bore offers 2513 N push at 0.5 MPa if your load is lighter, while the 125 mm bore jumps to 6136 N for heavier demands. The 100 mm adjuster window is ideal when you need to share one spare cylinder across multiple stroke variants or dial in a precise end position on the machine. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2. Because the stroke here is under 300 mm, side-load risks are minimal, but always guide the load for any stroke over 300 mm. Without live air this cylinder will not hold a load, so add an external rod lock or pilot-operated check valve if drift is unacceptable.
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 JSIJ100X100-100 FAQ
At 0.5 MPa it pushes 3927 N and pulls 3574 N. At 0.7 MPa it pushes 5497 N and pulls 5003 N. The theoretical maximum force is 801 kgf at 1.0 MPa. It uses a G1/2 port and a 33 mm adjustable air cushion at each end.
The nominal 100 mm extend stroke is the maximum. An external stop screw lets you shorten that extend stroke by up to 100 mm on-site, giving a usable range of 0 to 100 mm. The retract end is fixed. This mechanism sets the end position and is not a load lock.
