Linear bearings are a type of linear motion system that are widely used as sliding components in industrial machinery such as precision machine tools, textile machinery, and food packaging machinery. They roll with minimal frictional resistance through point contact between the load-bearing balls and the bearing housing, achieving smooth linear motion with high sensitivity and precision. Linear bearings are characterized by low friction and good stability, but their impact load capacity and load-bearing capacity are relatively weak, and they may generate significant vibration and noise during high-speed motion. Linear bearings are primarily categorized into standard and clearance-adjustable types, and can be classified into straight cylindrical and flange types based on their shapes. Additionally, there are plastic linear bearings, which possess self-lubricating properties, are suitable for high-load, medium-to-low-speed movements, and produce low noise. For the maintenance of linear bearings, attention should be paid to lubrication and dust prevention to ensure their long-term stable operation.
