The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X150-30STC is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm bore and 150mm 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 stop screw lets you shorten the forward travel by up to 30 mm, yielding a usable 120 to 150 mm range while the retract end remains fixed. This allows precise end-position tuning without swapping the actuator. The extruded hard-anodized aluminium barrel omits tie rods, making the body shorter and more compact than a same-bore ISO 15552 unit. It uses a G3/8 port and an M18x1.5 rod thread.
The included -S magnet enables position sensing via CMSE or DMSE switches fitted into the side grooves. Adjustable 29 mm air cushions at both ends manage end-of-stroke deceleration, though the cylinder relies on live air; an external rod lock or pilot-operated check valve is required to hold a load securely during pressure 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).

Shortens the extend stroke by 30 mm to push parts off a conveyor without readjusting the hard stop, accommodating varying product widths on the fly.
Fine-tunes the forward clamping reach within the 120 to 150 mm window, ensuring delicate components are held securely without over-travel.
Uses the TC mount for a pivoting trunnion fit and the external adjuster to dial in the exact stopping point for mixed pallet sizes.
The -30 mm adjustable window is particularly useful when sharing a spare cylinder across slightly different stroke variants or fine-tuning the final extended position on the machine. The TC trunnion mount present on this SKU provides a pivoting centerline interface. Because this unit includes the -S magnet, you can directly install CMSE/DMSE sensors. For any stroke length of 300 mm or greater, always guide the load to prevent side-load damage to the rod and front cover.
Quick checklist
The theoretical maximum force is 318 kgf at 1.0 MPa. This 63 mm bore model uses a G3/8 air port and features a 29 mm adjustable air cushion at both ends.
The nominal stroke is 150 mm, which is the maximum forward travel. An external stop screw allows you to shorten the extend stroke on-site by up to 30 mm, giving a usable range of 120 to 150 mm. The retract end is fixed, and this stop mechanism only sets the end position; it does not lock or hold the load.
