Linear bearings are a type of bearing that “bear” or support the load of the carriage during its single-axis linear movement and provide low friction sliding surface for the guide rails. In a linear guide, the carriage is the component that travels in a straight line curved line, back and forth, along the length of the guide rail, which is fitted and inserted into the linear bearing. They offer excellent precision, better mounting, and much smoother even motion. Its applications are found on cutting machines, machine sides, XY positioning tables, industrial robots, and instrumentation systems.
