Ball screw - a kind of linear drive that converts the rotational movement of the screw into the translational movement of the nut. The screw interacts with the nut not directly, but through the balls, which provides extremely low friction and, as a consequence - high transmission efficiency. The screw and nut are manufactured to tight tolerances and can be used in equipment where high movement and positioning accuracy is required.
- Ball screws provide a highly efficient transmission, the efficiency of which reaches 90%. The energy required to obtain a given force is 1/3 of compared to a normal pair of sliding.
- Ball screws can be preloaded to achieve high rigidity.
- The design of the ball screw is protected from dirt and chips inside the nut, which increases durability and transmission accuracy.
