Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X250-100S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X250-100S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 250mm 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 JSIJ100X250-100S
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 adjuster lets you shorten the extend stroke on-site by up to 100 mm, giving a usable forward range of 150-250 mm without swapping the cylinder. Because this is an -S SKU, the built-in piston magnet works directly with CMSE/DMSE reed or electronic switches in the side grooves. Air connects via the G1/2 port, and adjustable cushions decelerate the load at both ends.

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 JSIJ100X250-100S Is Used
Press Tonnage Trimming
Dial in the exact 150-250 mm extend reach on a light stamping press without machining new spacers, using the 100 mm external window to hit the precise contact point.
Vertical Lift Stops
Raise 200 kg materials in a lift rig and adjust the extend stop on the fly to match different shelf heights, using the built-in magnet for position feedback.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X250-100S the Right Cylinder?
The 100 mm adjuster window is ideal when you need to fine-tune the extend end position on-site or want a single shared spare across multiple stroke variants. Mounting options include FA, LB, TC, TCM1, and TCM2. For any stroke over 300 mm, always guide the load to prevent side-load wear on the rod seals.
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 JSIJ100X250-100S FAQ
The theoretical maximum force is 801 kgf at 1.0 MPa.
The nominal 250 mm extend stroke is the maximum. The external stop screw lets you shorten that forward travel on-site by up to 100 mm, yielding a usable range of 150-250 mm. The retract end remains fixed, and this mechanism only sets the end position, not a load lock.
