Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X80-50S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X80-50S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 80mm 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 JSIJ100X80-50S
The extruded hard-anodized aluminium barrel omits tie rods entirely, making the body shorter and more compact than a same-bore ISO 15552 unit.
The external stop screw lets you trim the extend stroke on-site by up to 50 mm, giving a usable forward range of 30 to 80 mm without swapping the actuator. Because this is an -S SKU, a built-in piston magnet works with CMSE/DMSE sensors in the side grooves for precise end-position feedback. Pneumatic connections use a G1/2 port, and adjustable air cushions at both ends absorb shock over the 33 mm cushion zone.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3525 N | 3525 N |
| 0.7 MPa | 4935 N | 4935 N |
| Max (@1.0 MPa) | 719 kgf | |
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 JSIJ100X80-50S Is Used
Press Tonnage Calibration
Dial in the exact 30 to 80 mm extend distance on-site to set precise pressing depths without machining custom spacers.
Heavy Pallet Diverter
Shift heavy 200 kg loads using the 100 mm bore power, tweaking the stop screw to match varying pallet widths instantly.
Vertical Lift Positioning
Lift materials safely and use the -S magnet with CMSE/DMSE sensors to confirm the adjusted upper reach every cycle.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X80-50S the Right Cylinder?
The 50 mm adjust window is ideal for sharing a single spare across multiple stroke variants or fine-tuning a machine setup on-site. Mounting choices include FA, LB, TC, TCM1, and TCM2 brackets. The -S magnet supports CMSE/DMSE switches for electronic or reed feedback. For any stroke length at or above 300 mm, always use an external guide rail to prevent side-load wear on the 32 mm rod.
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 JSIJ100X80-50S 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. The G1/2 port feeds the 32 mm rod.
The nominal 80 mm extend stroke is the maximum. An external stop screw lets you shorten that forward travel by up to 50 mm on-site, yielding a usable range of 30 to 80 mm. The retract end remains fixed.
