The AirTAC JSIJ32~50 Adjustable Cylinder JSIJ32X350-40S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø32mm bore and 350mm 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.
The hard-anodized aluminum extrusion omits tie rods entirely, and the G1/8 port keeps the pneumatic footprint tight.
The -40 code means an external adjuster can shorten the extend stroke on-site by up to 40 mm, giving a usable range of 310-350 mm without changing the cylinder itself. Because this is an -S SKU, a built-in piston magnet lets you drop CMSE or DMSE reed and electronic switches straight into the side grooves. Note that the retract end remains fixed, and the adjustable cushion only decelerates the piston rather than holding a load.

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 extend reach within the 310-350 mm window on-site to align a measurement gauge without swapping actuators.
Act as an adjustable stop fence on a conveyor, shortening the extend stroke by up to 40 mm to accommodate different product widths.
When sizing this unit, step down to a 32 mm bore for lighter duties or up to a 40 mm bore for 628 N at 0.5 MPa if you need more push. The 40 mm on-site extend-shortening window is ideal for fine-tuning end positions across shared spare cylinders. You can mount it via FA, LB, TC, TCM1, or TCM2 brackets. Because the 350 mm stroke creates leverage, always support the rod against side-load bending with an external guide. Remember that a plain cylinder drifts on air loss; use an external rod lock or pilot-operated check valve for held loads.
Quick checklist
At 0.5 MPa it pushes 402 N and pulls 345 N. At 0.7 MPa it pushes 563 N and pulls 483 N. The theoretical maximum force is 82 kgf at 1.0 MPa. It uses a G1/8 port and a 12 mm rod.
The nominal 350 mm stroke is the maximum. The external adjuster lets you shorten the extend stroke on-site by up to 40 mm, yielding a usable range of 310-350 mm. The retract end is fixed, and the stop only sets position rather than locking the load.
