The linear bearing is an important component of the linear guide. Through the bearing, the steel ball rotates with a very small frictional resistance, so that high-precision smooth motion can be obtained.
There are many ways to move the bearing. There are mainly servo motor stepping motors, and it is also useful to rotate the cylinder to convert the rotary motion into parallel movement.
At present, the bearings are widely used in sliding parts of industrial machinery such as multi-axis machine tools, punching machines, tool grinders, automatic gas cutting machines, printers, card sorting machines, food packaging machines, etc., as well as electronic equipment, tensile testing machines and digital three-dimensional coordinate measuring equipment. Equipment, the use is very extensive
