Linear bearing's introduction
Linear bearing is a linear motion system, used for linear travel and cylindrical axis. Because of the contact between the bearing ball and the bearing jacket point, the steel ball rolls with the minimum friction resistance, so the linear bearing has low friction and relatively stable friction. It does not change with the bearing speed, and can obtain stable linear motion with high sensitivity and precision. 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 linear motion system with self-lubricating characteristics. The biggest difference between it and metal linear bearing is that metal linear bearing is rolling friction and point contact between bearing and cylinder shaft. 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
