Linear bearing is a kind of linear motion system for straight line travel used with cylindrical shaft. Due to coat point contact ball bearing with bearing, steel ball roll with minimum friction resistance, so the linear bearing small friction, and relatively stable, not over bearing speed changes, and can obtain high sensitivity, high precision of stationary linear motion. Linear bearing consumption also has its limitations, is the main bearing impact load ability is poor, and poor bearing capacity also, second linear bearing vibration and noise is bigger when high speed movement. Linear bearing automatic fast easy optimal selection are included. Linear bearing is widely used in precision machine tools, textile machinery, food packaging machinery, printing machinery and other industrial machinery of sliding parts.Because of the point contact ball bearing with bearing, so using the load is small. Steel ball with minimal friction spinning, which can obtain high precision of smooth movement.Plastic linear bearing is a kind of system, the linear motion of the self-lubricating properties with the metal linear bearing is the biggest difference is that the metal linear bearing rolling friction, bearing and cylinder axis is point contact, so it is suitable for low load high speed movement; And plastic linear bearing is a sliding friction between bearing and cylinder shaft is surface contact, so the suitable for high load in the low speed movement.
Application: Electronic equipment, food machinery, packaging machinery, medical machinery, printing machinery, textile machinery, machinery and equipment, robots, tools, machinery, CNC machine tools, automobile and etc.
