Linear bearing description

The linear bearing is a linear motion system, which is used to match the linear stroke with the cylindrical shaft. As the bearing ball is in contact with the bearing coat, the steel ball rolls with the minimum friction resistance. Therefore, the linear bearing has low friction and is relatively stable, and does not change with the bearing speed.

Therefore, it can obtain stable linear motion with high sensitivity and high precision. Linear bearing consumption also has its limitations. The most important is that the bearing has poor impact load capacity and poor bearing capacity. Secondly, linear bearing has great vibration and noise when moving at high speed. Linear bearing rapid, easy and automatic selection has been included. Linear bearings are widely used in precision machine tools, textile machinery, food packaging machinery, printing machinery and other industrial machinery sliding parts.

The load is small because the bearing ball contacts the bearing point. The steel ball rotates with minimal friction resistance, thus achieving high precision and smooth motion.
Plastic linear bearings are self-lubricating linear motion system. The biggest difference between them and metal linear bearings is that they are rolling friction. While the plastic linear bearing is sliding friction, the bearing and cylindrical shaft are face contact, so this is suitable for high load, medium and low speed motion.
