THK KR46 Series LM Guide Actuator

The THK KR46 is a high-performance LM Guide actuator that integrates a precision ball screw and linear guide system into a single compact unit. Its rigid one-piece structure reduces deflection and ensures stable operation while simplifying installation and alignment, making it well suited for general-purpose automation applications requiring smooth, accurate, and reliable linear motion.

Supporting a wide range of stroke lengths and ball screw leads, the KR46 offers flexibility for both high-speed transport and precise positioning within the same platform. The integrated design eliminates the need for separate linear guide and ball screw components, reducing assembly time and overall system footprint for machine builders and system integrators.
