Linear bearing is a kind of linear motion system, which is used for linear stroke and cylindrical shaft. Because the bearing ball is in point contact with the bearing sleeve, the steel ball rolls with the minimum friction resistance, so the linear bearing has small friction and is relatively stable, and it does not change with the bearing speed, and can obtain a stable linear motion with high sensitivity and precision.

• The plastic linear bearing is a linear motion system with self-lubricating characteristics. The biggest difference between it and the metal linear bearing is that the metal linear bearing is rolling friction and the bearing is in point contact with the cylindrical shaft, so it is suitable for low load and high speed motion. The plastic linear bearing is sliding friction
• Linear bearing is used in conjunction with the quenched linear transmission shaft. A system that moves in an infinite straight line. Because the load ball is in point contact with the quenching transmission shaft, the allowable load is small, but when moving in a straight line, the friction resistance is the smallest, the precision is high and the movement is fast.
• Maintenance of plastic linear bearing: Because the sliding film inside the plastic linear bearing is made of self-lubricating plastic, it does not need extra oil supply and maintenance during use; Moreover, because the plastic linear bearing is provided with a chip removal groove, even if the bearing or shaft is full of dust, it does not need to be maintained
• Friction resistance is small and stable. The design of linear bearing makes it have less friction resistance during operation, which helps to improve mechanical efficiency and reduce energy consumption.
• Linear bearing is more and more widely used in electronic equipment, food machinery, packaging machinery, medical machinery, printing machinery, textile machinery, machinery, instruments, robots, tool machinery, CNC machine tools, automobiles and digital three-dimensional coordinate measuring equipment and other precision equipment or special machinery industries.
