THK’s LM Guide Actuator Caged Ball LM Guide Actuator SKR26 with Long Nut Block A/B SERIES represents a significant advancement in linear motion technology, engineered to deliver exceptional precision, rigidity, and durability in demanding industrial environments. This system integrates a recirculating ball mechanism within a caged structure, ensuring smooth, low-friction linear travel with minimal maintenance requirements. The SKR26 model features a compact design with a 26mm rail width, optimized for applications where space constraints and high load capacities are critical. The inclusion of the Long Nut Block in A or B SERIES configurations enhances mounting flexibility and load distribution, allowing for secure integration into various machinery setups.

Key technical features include the caged ball design, which prevents ball-to-ball contact and reduces wear, noise, and vibration. This results in a longer service life and consistent performance under high-speed and high-load conditions. The LM Guide Actuator incorporates precision-ground raceways and balls, achieving high accuracy with minimal deflection. The Long Nut Block is designed for easy installation and adjustment, featuring tapped holes and standardized dimensions that simplify alignment and reduce assembly time. Additionally, the system is pre-lubricated and sealed to resist contaminants like dust and moisture, making it suitable for harsh environments without frequent re-lubrication.

Performance advantages of the SKR26 series are evident in its ability to handle combined loads—including radial, reverse radial, and lateral forces—with high stiffness and positional accuracy. This makes it ideal for applications requiring repeatable linear motion, such as in CNC machining centers, where it ensures precise tool positioning and reduced cycle times. In automotive systems, the actuator is used in robotic welding arms and assembly lines, providing reliable movement for components like engine parts or chassis fixtures. Its low friction coefficient contributes to energy efficiency, reducing operational costs over time. For precision equipment, such as semiconductor manufacturing or medical devices, the SKR26’s smooth operation minimizes vibration, critical for maintaining product quality in processes like wafer handling or diagnostic instrument positioning.

Typical applications span across industrial machinery, where it supports linear slides in packaging equipment and material handling systems, enabling fast, accurate product transfer. In automotive automation, it facilitates precise control in brake testing rigs or powertrain assembly, enhancing productivity and safety. The actuator’s robustness also suits it for use in precision inspection machines, where stability and accuracy are paramount for measuring components in quality assurance processes. Overall, THK’s SKR26 LM Guide Actuator with Long Nut Block A/B SERIES offers a reliable solution for industries prioritizing efficiency, longevity, and precision in linear motion systems.
