THK KR45H Series LM Guide Actuator

The THK KR45H is a high-rigidity LM Guide actuator that integrates a precision ball screw and linear guide system into a single compact unit. Designed for applications requiring higher load capacity and rigidity than standard actuator series, the KR45H delivers smooth and accurate positioning with excellent durability suited for demanding automation and transfer systems.

Its high-accuracy LM Guide structure supports heavier loads and longer strokes, making it a practical choice for machine builders and system integrators working with more demanding linear motion requirements. The compact all-in-one design simplifies installation, reduces alignment time, and lowers overall maintenance requirements compared to separate component assemblies.
