THK’s LM Guide RSX M1WN SERIES represents a specialized evolution in linear motion technology, engineered specifically for high-temperature environments where conventional guides would falter. This full ball type LM Guide incorporates a robust, heat-resistant design that maintains precision and reliability even when exposed to temperatures up to 150°C continuously, with peak tolerance reaching 200°C. The core of its construction lies in the use of specially formulated heat-resistant resins for the end seals and LM block, alongside stainless steel end plates, ensuring structural integrity and corrosion resistance under thermal stress. The ball grooves are precision-ground with a Gothic arch profile, optimizing contact points to distribute loads evenly and minimize friction, while the full ball recirculation system ensures smooth, uninterrupted motion by maintaining constant ball contact within the load-bearing raceways.

Key technical features include a compact LM block design that saves space without compromising load capacity, thanks to its high rigidity and four-row circular arc groove configuration. The inclusion of high-performance seals—such as the steel scrapers and specialized grease seals—effectively prevents contaminants like dust, chips, and moisture from infiltrating the ball recirculation paths, even in harsh conditions. This is complemented by a pre-load adjustment mechanism that allows for fine-tuning to eliminate backlash, enhancing positional accuracy and stability during operation. The RSX M1WN SERIES also supports high-speed applications, with its optimized recirculation system reducing noise and vibration, which is critical for maintaining smooth motion profiles in dynamic setups.

Performance advantages of this series are evident in its ability to deliver consistent precision and longevity under thermal duress. The heat-resistant components resist deformation and degradation, extending service life and reducing maintenance intervals in demanding settings. Its high load capacity—supporting moments and loads in all directions—makes it suitable for applications involving heavy or uneven forces, while the low friction coefficient contributes to energy efficiency by minimizing power consumption. Additionally, the guide’s corrosion-resistant properties, derived from stainless steel elements, make it ideal for environments with exposure to coolants, chemicals, or humidity, further broadening its applicability.

Typical applications span industries where high temperatures and precision are paramount. In industrial machinery, the RSX M1WN SERIES is deployed in injection molding machines, where it guides ejector units and moving platens exposed to heat from molten plastics, ensuring repeatable cycles without loss of accuracy. Automotive systems leverage these guides in welding robots and paint shop automation, where elevated temperatures from processes or ovens demand reliable linear motion for assembly line consistency. In precision equipment, such as semiconductor manufacturing tools or glass processing machinery, the series provides stable guidance for stages and actuators in heated chambers, supporting micron-level accuracy in tasks like wafer handling or laser cutting. By combining thermal resilience with high-performance mechanics, THK’s RSX M1WN SERIES enables enhanced productivity and reliability across these critical sectors.
