The AirTAC JSIJ32~50 Adjustable Cylinder JSIJ32X100-10 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø32mm bore and 100mm stroke, G1/8 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.
Its external adjuster shortens the extend stroke by up to 10 mm, yielding a usable 90-100 mm window while the retract end stays fixed. This built-in flexibility means you can fine-tune the stroke without swapping the cylinder. The hard-anodized aluminum profile barrel keeps the total length shorter than a same-bore ISO 15552 unit.
The G1/8 port and adjustable 20 mm air cushions at both ends ensure smooth deceleration. Note that this plain SKU lacks a magnet and cannot take CMSE or DMSE sensors; adding the -S variant enables switch readiness. Furthermore, the cushion only decelerates the piston, so fit an external rod lock or pilot-operated check valve if you need to hold a load on air loss.

| Max (@1.0 MPa) | 70 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).

Dial in the exact 90 to 100 mm clamping reach on a machining fixture using the external stop screw without replacing the actuator.
Fine-tune the ejection stroke on a 32 mm bore assembly line to accommodate varying product heights while maintaining smooth cushioning.
Adjust the extend stop on a conveyor diverter by up to 10 mm to perfectly halt different carton sizes on the fly.
The adjustable 10 mm extend window is ideal for sharing a single spare across multiple stroke variants or dialing in a final end position on-site. You can mount it via Basic, FA, LB, TC, TCM1, or TCM2 brackets. Because this specific SKU lacks the -S magnet, it cannot support position sensing. For any stroke at or over 300 mm, always use a guide rail to prevent side-load damage to the rod.
Quick checklist
This 32 mm bore actuator pushes 402 N and pulls 345 N at 0.5 MPa, and pushes 563 N while pulling 483 N at 0.7 MPa. The theoretical maximum force is 82 kgf at 1.0 MPa. It uses a G1/8 air port and features a 12 mm rod with an M10x1.25 thread.
The external adjuster lets you shorten the extend stroke by up to 10 mm on-site, giving a usable extend range of 90 to 100 mm. The nominal 100 mm stroke is the maximum, and the retract end remains fixed. This stop sets the end position but does not lock the load.
