THK KR4610D440LP0-1X00 Linear Motion Actuator

The THK KR4610D440LP0-1X00 is a compact, ball-screw-driven LM Guide linear motion actuator in THK’s KR46 Compact Series designed for high-speed, high-precision positioning in industrial automation and precision equipment. This D-type dual short-block actuator combines an integrated LM Guide with a precision ball screw (10 mm lead) and offers a stroke of approximately 440 mm, delivering smooth, high-rigidity motion within a U-shaped outer rail and integrated moving table. Key specifications include the KR46 series, Model Type D (Dual Short Block), Drive Method: Precision Ball Screw, Ball Screw Lead: 10 mm, Stroke: ~440 mm, Basic Dynamic Load Rating (LM Guide Unit): 14,000 N, Basic Static Load Rating (LM Guide Unit): 22,700 N, and a Four-Way Equal Load Design. It is commonly used in semiconductor equipment, CNC machining centers, industrial robots, automated inspection machines, packaging machinery, laboratory automation, and material handling systems, with applications for maintenance teams, OEM machine builders, and system integrators for repairs, automation upgrades, and replacements. Optional contamination protection is available, including bellows, QZ lubricator, sensors, and mounting accessories, and the unit supports direct motor coupling for simplified installation.
