Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X200-10S
The AirTAC Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X200-10S 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 JSIJ125X200-10S
Delivering 6136 N of push force at 0.5 MPa, this 125 mm bore JIS profile cylinder packs serious power into a body noticeably shorter than a same-bore ISO 15552 unit. The hard-anodized aluminum extrusion omits tie rods entirely for a clean exterior. It handles about 3682 N of safe working load, which translates to lifting roughly 313 kg vertically with a 2:1 margin.
The JSIJ125X200-10S variant uses an external stop screw to trim the extend stroke by up to 10 mm on site, giving a usable forward range of 190 to 200 mm while the retract end stays fixed. A built-in magnet (-S) allows CMSE or DMSE sensors to clip directly into the side grooves. Air connections use a G1/2 port, and adjustable cushions decelerate the 32 mm rod smoothly at each end.

Where the Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X200-10S Is Used
Press Tonnage Trimming
Use the 6136 N thrust for light pressing tasks, dialing in the exact 190-200 mm extend contact point via the external stop screw without swapping cylinders.
Heavy Vertical Lowering
Lower payloads up to 313 kg safely with a 2:1 margin, relying on the 33 mm adjustable cushions to brake the rod gently before the fixed retract end.
Pallet Stop Gate
Deploy this compact JIS profile cylinder as a heavy pallet stop, using the -S magnet and DMSE sensors to confirm gate extension for the PLC.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X200-10S the Right Cylinder?
When sizing this unit, the neighboring 100 mm bore yields 3927 N push at 0.5 MPa, while stepping up is not possible as 125 mm is the maximum frame. The 10 mm extend-shortening window is ideal for final end-position tuning without remounting hardware. Choose from Basic, FA, LB, TC, TCM1, or TCM2 mounting styles. The -S magnet supports CMSE/DMSE switches for position feedback. Because the 200 mm stroke exceeds 300 mm only marginally, side-load guides are recommended for rigid stability. Remember that the external adjuster sets the end position; it does not lock the load.
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 JSIJ125X200-10S FAQ
At 0.5 MPa it pushes 6136 N and pulls 5734 N. At 0.7 MPa push is 8590 N and pull is 8028 N. The theoretical max force is 1251 kgf at 1.0 MPa. It features a 32 mm rod, M27x2.0 rod thread, G1/2 port, 33 mm adjustable cushions, and operates at 30-500 mm/s.
The nominal 200 mm stroke is the maximum. The external adjuster lets you shorten the extend stroke by up to 10 mm on site, yielding a usable range of 190 to 200 mm for fine-tuning the end position. The retract end remains fixed. This mechanism only sets position; it does not hold the load on air loss.
