THK KR Series Full-Ball Type LM Guide Actuator

The KR Series Full-Ball Type LM Guide Actuator is a high-rigidity, high-accuracy linear actuator designed for space-efficient installations.

Its inner block integrates a highly rigid U-shaped outer rail, LM Guide units on both side faces, and a ball screw unit at the center. This integrated structure delivers excellent rigidity and positioning accuracy while minimizing overall size, making the KR suitable for precision automation applications with limited installation space.

In addition, the A and B housings also function as support units, while the inner block serves as the table. This integrated design eliminates the need for separate support units and table structures, allowing a significant reduction in design and assembly time.

As a result, the Model KR helps shorten machine development time and reduce overall system cost, making it an efficient solution for precision automation and compact linear motion systems.
