Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X500-75S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X500-75S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 500mm 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 JSIJ100X500-75S
The hard-anodized aluminium barrel keeps the total length shorter than a same-bore ISO 15552 unit.
The external stop screw lets you trim the extend stroke on-site across a 425-500 mm window, giving you a 75 mm fine-tuning range without swapping the cylinder. Air connects via a G1/2 port, and the -S suffix means a built-in magnet is ready for CMSE/DMSE sensors in the side grooves. Adjustable 33 mm cushions decelerate the load at both ends, though a plain cylinder drifts on air loss, so fit an external rod lock for held loads.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|

JSIJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative).

Where the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X500-75S Is Used
Pallet Diverter Stop
Fine-tune the 425-500 mm extend stop on-site to match varying pallet widths without remounting the actuator.
Multi-Size Carton Loading
Use the G1/2 port and adjustable stroke to set precise push distances for different packaging heights on a shared line.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X500-75S the Right Cylinder?
The 75 mm adjustable window is ideal for sharing a single spare cylinder across machines that need slightly different extend end-positions. JSIJ mounting choices include FA, LB, TC, TCM1, and TCM2. Because the stroke is 500 mm, always support the load with an external guide to prevent rod bending and excessive side-load wear. The -S magnet enables precise end-of-stroke detection with CMSE or 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 JSIJ100X500-75S 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 is 801 kgf at 1.0 MPa. The air port is G1/2.
The nominal 500 mm extend stroke is the maximum. The external adjuster lets you shorten the extend end-position by up to 75 mm on-site, giving a usable extend range of 425-500 mm. The retract end remains fixed.
