THK KR3310A-0200-P LM Precision Linear Positioner

Description:

The THK KR3310A-0200-P LM Precision Linear Positioner is a compact, high-precision linear actuator integrating an LM Guide and precision ball screw with a 10 mm lead and 200 mm travel for fast, accurate linear motion. Commonly installed in factory automation systems, CNC machinery, semiconductor equipment, robotics, inspection systems, packaging machinery, and precision assembly equipment requiring high-speed positioning. Machine builders, maintenance technicians, and system integrators use this actuator for new machine construction, automation upgrades, retrofits, and replacement of worn linear motion assemblies.

Applications:

The THK KR3310A-0200-P belongs to THK's KR33 LM Guide Actuator Series, combining a U-shaped high-rigidity outer rail, precision LM Guide blocks, and an integrated ball screw into a single compact assembly. The 10 mm lead provides higher travel speeds than the 6 mm version while maintaining excellent positioning repeatability. Designed for direct coupling to a NEMA 23 stepper or servo motor, this actuator offers smooth, low-friction operation, high rigidity, and four-way equal load capability, making it suitable for automated pick-and-place systems, material handling, precision inspection equipment, medical devices, and industrial manufacturing applications.
