This paper describes the lubricating characteristics of LM-guide at the point of out-particles from LM-guide. After, we investigated the contents of out-particles, we did improve in lubricants and in structure of LM-guide for low out-particles. We can reach "Super clean guide" using new structure and new lubricating grease (AFE or AFF). This "Super clean guide" can provide extremely low out-particles characteristics of less than 1% of normal liner motion guide.
