The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X500-50S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm bore and 500mm stroke, G3/8 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 external adjuster allows you to shorten the extend stroke on-site by up to 50 mm, meaning the usable extension range is 450-500 mm while the retract end remains fixed. This on-site adaptability lets you fine-tune the stroke without physically changing the cylinder. The extruded hard-anodized aluminium profile barrel contains no tie rods, making the overall body shorter and more compact than a same-bore ISO 15552 unit.
Equipped with a -S suffix, this model features a built-in piston magnet for CMSE/DMSE sensors that drop directly into the side grooves. Air connections use a G3/8 port, and adjustable air cushions of 29 mm at each end decelerate the piston smoothly. Remember that the cushion only slows the load; an external rod lock or pilot-operated check valve is required to hold a load securely on air loss.

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).

Allows operators to fine-tune the 450-500 mm extend position of a sorting diverter on-site without swapping cylinders, ensuring packages hit the correct lane.
Acts as a movable end-stop for varying pallet sizes on a roller line, using the external adjuster to shorten the extend stroke exactly where the load needs to halt.
Provides a 63 mm bore pressing force with a tweakable end position, letting maintenance dial in the exact 450-500 mm extension for different workpiece heights.
The adjustable -50 mm window is highly useful when you need to share a single spare cylinder across multiple stroke variants or perform on-site end-position tuning. JSIJ mounting options include Basic, FA, LB, TC, TCM1, and TCM2. Because the stroke is 500 mm, you must account for side-load risks and use external guides to prevent rod bending. The integrated magnet supports CMSE/DMSE switches for position sensing.
Quick checklist
This 63 mm bore cylinder uses a G3/8 port and a 20 mm piston rod with an M18x1.5 thread. The theoretical maximum force is 318 kgf at 1.0 MPa. Adjustable air cushions are 29 mm at both ends, and operating speed ranges from 30-800 mm/s.
The -50 code means an external stop screw lets you shorten the extend stroke on-site by up to 50 mm. The nominal 500 mm stroke is the maximum, so the usable extension range is 450-500 mm. The retract end is fixed. This stop only sets the end position; it is not a load lock, so you need an external rod lock or pilot-operated check valve to hold a load securely.
