Introduction to the linear bearing
Linear bearing is a linear motion system, used for linear travel and cylindrical axis. 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. The consumption of linear bearing also has its limitation. The most important one is that the bearing has poor impact load capacity and poor bearing capacity.
Linear bearing quick and easy to optimize automatic selection included. Linear bearings are widely used in precision machine tools, textile machinery, food packaging machinery, printing machinery and other industrial machinery sliding components.Because the bearing ball is in contact with the bearing point, the load is small. The ball rotates with minimal friction resistance, thus achieving high precision smooth motion.
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; The plastic linear bearing is sliding friction, and the surface contact between the bearing and the cylinder shaft is surface contact, so it is suitable for high load and low speed motion.
