What is Preloading and why it is done? Preload is the elimination of internal clearance between the rail and carriage or between the ball screw and ball nut. This makes the system more rigid by creating a load on the linear guide or ball screw, which reduces deflection when an external force is applied. Preloading is used to increase the accuracy and rigidity of a ball screw system. It makes the…

A ball screw is a mechanical linear actuator that translates rotational motion to linear motion with little friction. A threaded shaft provides a helical raceway for ball bearings which act as a precision screw. As well as being able to apply or withstand high thrust loads, they can do so with minimum internal friction. They are made to close tolerances and are therefore suitable for use in situations in which high precision is necessary. The ball assembly…

Linear Guideway is one of the important elements of the machine tool. Its main function is to make sure that the cutting tool or machine tool element moves along a predetermined path. LM Guide provides smooth and linear motion in machine tools, due to which higher accuracy and precision can be obtained. A linear guideway allows a type of linear motion that utilizes elements such as rolling balls. By using…
