Linear shaft is a commonly used mechanical element to guide linear motion. Common types of shafts are crankshaft, straight shaft and flexible shaft. It is used for infinite travel in conjunction with a cylindrical shaft. Since the bearing ball is in point contact with the shaft, the use load is small. The steel ball rotates with a small frictional resistance, so that a smooth movement with high precision can be obtained. Linear axis is widely used in electronic equipment, tensile testing machine and digital three-dimensional coordinate measuring equipment and other precision equipment, as well as multi-axis machine tools, punching machines, tool grinders, automatic gas cutting machines, printers, card sorting machines, food packaging machines and other industrial machinery sliding parts.

1, and linear guide has the same function, are used as support and movement. The difference between the two lies in the installation site, and the shape is also different. The optical axis is circular, and the linear guide rail is generally square. There is a fixed installation slider processed on it. The straight optical axis is generally fixed at both ends, and the middle suspended connecting component covers all or most of the radial direction of the optical axis. Linear guide rail is generally one side all close to the equipment installation base, fixed with bolts.
2. Linear shaft is used in conjunction with linear bearings and cylindrical shafts. Because the bearing ball is in point contact with the bearing jacket, the steel ball rolls with a small frictional resistance, so the linear optical axis has a small friction and is relatively stable, does not change with the bearing speed, and can obtain a smooth linear motion with high sensitivity and high precision.
3. The linear guide has higher precision than the linear bearing, greater load and stronger stability.
4, linear shaft consumption also has its limitations, the main is the linear bearing impact load capacity is poor, and the carrying capacity is also poor; there is a linear shaft in high-speed motion vibration and noise, which are the problems faced by the industry.
