LM-UU is a standard type linear bearing, where 'LM' represents its widespread use in the Asian region, and 'UU' denotes its double-sealing feature. Its design, compliant with metric standards, includes a cylindrical-shaped outer tube, an inner retainer with steel balls, and dual-sealed retaining rings at both ends to securely fasten the retainer to the outer tube. Furthermore, the retainer's guide loop design ensures smooth circulation of steel balls, providing efficient and reliable motion control, making it stand out in various applications widely used across Asia.
Linear bearings achieve linear motion through the rotary motion of steel balls. As the load-bearing balls only make point contact with the bearing outer sleeve, they roll with minimal friction resistance. Therefore, linear bearings have low friction and relatively stable performance, maintaining high precision, low noise, and high rigidity even when carrying heavy loads.
Linear bearings are suitable for designing compact mechanisms that effectively utilize space by using circular axis centers. They can be selected according to different environments. Linear motion elements using the rotary motion of steel balls have simple structures and low friction, making them suitable for linear motion mechanisms used in semiconductor manufacturing, food machinery, precision machine tools, and other fields.
