The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X25-10 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 25mm 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.
The extruded hard-anodized aluminium barrel keeps the overall length shorter than a same-bore ISO 15552 cylinder, saving valuable machine space.
The external stop screw provides a 10 mm on-site extend-shortening window, letting you fine-tune the usable extend stroke down from the 25 mm maximum to 15 mm without changing the cylinder itself. Air connections use a G1/2 port, and adjustable air cushions at both ends decelerate the load smoothly. Note that this plain SKU lacks a magnet and cannot take a CMSE/DMSE sensor; for the switch set you need the -S variant.

Specifications follow the official AirTAC JSI (JIS standard) datasheet. Confirm against the product label before installation. Thread options: PT (blank) / G. Barrel: hard-anodized aluminum profile (no tie rods).
| 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).

| 100 | Bore size in mm (32 / 40 / 50 / 63 / 80 / 100 / 125). |
| ×25 | Stroke length in mm. |
| -S | Optional built-in magnet for CMSE / DMSE sensors. |
JSI-family variants: JSI (double acting), JSID (double rod), JSIJ (adjustable stroke). Mounting: LB / FA / FB / CA / CB / CR / TC / TCM1 / TCM2. Thread PT (blank) / G.
Dial in the exact 15 to 25 mm pressing depth for bearing insertion using the external adjuster, ensuring perfect seating without swapping actuators.
Provides a hard mechanical stop for clamping parts, allowing operators to back off the extend position by up to 10 mm to prevent workpiece deformation.
The 10 mm adjuster is ideal for sharing a spare across slightly different short-stroke variants and tuning the final end position on-site. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Because this is a no-magnet SKU, position sensing is unavailable here. Even at this short 25 mm stroke, ensure adequate guide support to absorb any side loads.
Quick checklist
The theoretical maximum force is 801 kgf at 1.0 MPa.
The nominal 25 mm extend stroke is the maximum. The external adjuster lets you shorten the extend stroke on-site by up to 10 mm, giving a usable extend range of 15 to 25 mm. The retract end is fixed, and the stop only sets position, it does not lock the load.
