After using straight line bearing, keeping no direct contact between bore and shaft, but by means of possessing micro no clearance steel ball between them, therefore, they have high motion precision. Friction of rolling is substitued for sliding friction which which has active rolling, low friction factor and long service life. In the situation of both rolling and moving, matching the shaft sleeve of no oil or adding oil with the shaft, although they can be met and have low motion precision. They can only meet in the situation of the shaft with relative motion, but the straight-line bearing can all meet above-mentioned two conditions. At present, It is widely used in cool die frames, high precision machine tools, machine tool accessories and requiring high-precision axial or radial simultaneous move situation.
