Linear Bearings is a low-cost production of linear motion system for unlimited travel used in conjunction with the cylindrical shaft. The ball bearing was due to point contact with the shaft, so the use of a small load. With minimal friction ball spin, giving them access to high-precision smooth movement.Linear bearings are widely used in electronic equipment, tensile testing machine and the digital three-dimensional coordinate measuring equipment and precision equipment, as well as multi-axis machine, punching machine, tool grinder, automatic gas cutting machine, printer, card sorting machine, food packing machines and other industrial machinery sliding components.
