THK’s LM Guide Actuator Caged Ball LM Guide Actuator SKR26 series represents a sophisticated integration of linear motion components engineered for high precision, rigidity, and reliability in demanding applications. This system combines a compact LM Guide Actuator with a caged ball design, featuring a motor wrap, long nut, and block configurations in A and B series variants. The SKR26 model is specifically designed to deliver smooth, accurate linear motion while minimizing maintenance requirements and operational noise.

Key technical features include the caged ball mechanism, which separates and retains ball bearings within the guide to prevent contact and reduce friction, significantly enhancing operational smoothness and lifespan. The actuator incorporates a precision-ground rail and block assembly, ensuring minimal deflection under load. The motor wrap allows for seamless integration with servo or stepper motors, providing precise control over linear positioning. The long nut design offers extended engagement for higher load capacity and improved moment resistance, while the A and B series blocks cater to different mounting and space constraints, with variations in preload and sealing options to suit diverse environmental conditions.

Performance advantages are substantial, starting with exceptional positional accuracy and repeatability, critical for applications requiring micron-level precision. The caged ball system reduces heat generation and wear, contributing to a longer service life even in high-speed or high-frequency cycling scenarios. With high rigidity and load capacity, the SKR26 actuator supports both radial and moment loads effectively, making it suitable for dynamic applications. Its low friction coefficient results in energy-efficient operation, and the inclusion of seals and wipers in the block design protects against contaminants like dust and moisture, ensuring reliability in harsh industrial environments.

Typical applications span across industrial machinery, where the SKR26 series is employed in CNC machining centers for tool positioning, automated assembly lines for precise part handling, and semiconductor manufacturing equipment requiring vibration-free motion. In automotive systems, it facilitates precise movements in robotic welding arms, engine component testing fixtures, and automated paint sprayers. For precision equipment, this actuator is ideal for optical alignment systems, medical device manufacturing stages, and coordinate measuring machines, where stability and accuracy are paramount. Its versatility and robust design make it a cornerstone in advancing automation and precision across multiple sectors.
