Accuracy Grades: The accuracy grade is a key parameter for linear guideways. The suffix "CC" likely signifies a specific accuracy combination (e.g., running parallelism, height tolerance) and preload level (referring to the internal prestress applied via the interference fit between the balls and raceways during manufacturing). The preload directly affects the guideway's rigidity, smoothness of operation, and accuracy lifespan
。Selection Considerations: When selecting a model, in addition to confirming the installation dimensions (like the slider width of 20mm), it is crucial to clarify the required accuracy grade (e.g., Normal C, High H, Precision P) and preload grade (typically categorized as light preload, medium preload, heavy preload) based on the application requirements to ensure the product performance meets expectations
。Lubrication and Maintenance: Proper lubrication is essential for the long-term accuracy and service life of linear guideways. Grease or oil can be selected, paying attention to the lubrication interval. Additionally, appropriate dust protection devices, such as scrapers and end seals, should be equipped according to the operating environment to prevent dust and debris from entering the slider interior
