✅ Typical Applications
-- 3C electronics micro jig, chip transportation, connector insertion;
-- Medical equipment sample processing, micro pushing mechanism;
-- Semiconductor wafer positioning, clean room miniature actuator;
-- Automation stopper, short stroke clamping and positioning.
⚠️ Selection Reminders
-- Not suitable for heavy side offset load; add guide if lateral force exists.
-- Magnetic shield plate required when multiple cylinders installed side by side.
SOLH CDUJB ultra compact free mount pneumatic cylinder enables multi-direction bracketless installation, ideal micro linear actuator for limited-space precision automation in 3C, medical and semiconductor industries.
