Linear bearing: Metal linear bearing is a low-cost linear motion system designed for use with infinite travel and cylindrical shafts. Widely used as sliding parts in industrial machinery such as precision machine tools, textile machinery, food packaging machinery, printing machinery, etc

Introduction:

Linear bearings are a type of linear motion system used in conjunction with cylindrical shafts for linear travel. Due to the contact between the bearing ball and the outer sleeve of the bearing, the steel ball rolls with minimal frictional resistance. Therefore, linear bearings have low friction, are relatively stable, and do not change with the bearing speed. They can achieve stable linear motion with high sensitivity and accuracy. The consumption of linear bearings also has its limitations, mainly due to the poor impact load capacity and load-bearing capacity of the bearings. Secondly, linear bearings experience significant vibration and noise during high-speed motion. The automatic selection of linear bearings is included. Linear bearings are widely used as sliding components in industrial machinery such as precision machine tools, textile machinery, food packaging machinery, printing machinery, etc

Due to the contact between the bearing ball and the bearing point, a small load is used. The steel ball rotates with minimal frictional resistance, allowing for high-precision and smooth motion.

Plastic linear bearings are a self-lubricating linear motion system, and their biggest difference from metal linear bearings is that metal linear bearings have rolling friction and point contact with cylindrical shafts, making them suitable for low load high-speed motion; Plastic linear bearings have sliding friction and are in surface contact with cylindrical shafts, making them suitable for high load and low-speed motion.
