Description

Linear bearing is a linear motion system, which is used in combination with a cylindrical shaft for wireless travel. Because the bearing ball contacts the bearing outer sleeve point, the linear bearing has the advantages of small friction, high stability, and does not change with the bearing speed. It can obtain a stable linear motion with high sensitivity and precision.
