SMC CJ2B1630SZ (CJ2B16-30SZ) - Mini Air Cylinder, 16mm Bore, 30mm Stroke

SMC CJ2B1630SZ Mini Air Cylinder — 16mm bore, 30mm stroke, SINGLE ACTING SPRING RETURN (S), basic (B) mounting, head cover port PERPENDICULAR to axis. Differs from CJ2B16-30SRZ, which adds R = axial head cover port, and from CJ2B16-30Z, which is double acting. CJ2 without leading D means WITHOUT built-in magnet - not auto-switch capable. SMC CJ2B16-30SZ is a CJ2-Z series mini air cylinder with a 16 mm bore and 30 mm standard stroke. The S suffix denotes single acting, spring return action - air extends the rod and an internal spring retracts it when air is removed. Mounting style B is basic (through) mounting and the head cover port is perpendicular to the axis (the standard side port), which is the sole difference from CJ2B16-30SRZ. The CJ2 prefix (no leading D) confirms the cylinder is supplied WITHOUT a built-in magnet and cannot accept auto switches. Standard, not made-to-order.

CJ2B16-30SZ Applications

Used where a 30 mm stroke must retract automatically on loss of air, giving inherently fail-safe behaviour for clamps, stops, ejectors and hold-down devices on assembly and packaging lines. The standard side port suits conventional tubing runs. Air is consumed only on the extend stroke, favouring high-cycle duties. Since no magnet is built in, end-of-stroke sensing must be handled by external limit switches instead of auto switches.
