We are counted among the top Exporters and Suppliers of Ball Screw in the markets of Indian Subcontinent, Middle East, East Asia and South East Asia. 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, Ball Screws can do so with minimum internal friction. Ball Screw is made to close tolerances and therefore suitable for use in situations in which high precision is necessary. The Ball Assembly acts as the nut while the threaded shaft is the screw. In contrast to conventional lead screws, Ball Screws tend to be rather bulky, due to the need to have a mechanism to re-circulate the balls.   Description and Operation To maintain their inherent accuracy and ensure long life, great care is needed to avoid contamination with dirt and abrasive particles. This may be achieved by using rubber or leather bellows to completely or partially enclose the working surfaces. Another solution is to use a positive pressure of filtered air when they are used in a semi-sealed or open enclosure. While reducing friction, Ball Screws can operate with some preload, effectively eliminating backlash (slop) between input (rotation) and output (Linear motion). This feature is essential when they are used in computer-controlled motion-control systems, e.g., CNC machine tools and high precision motion applications (e.g., wire bonding). Advantages Low friction in Ball Screw yields high mechanical efficiency compared to alternatives. A typical Ball Screw may be 90 percent efficient, versus 50 percent efficiency of an Acme lead screw of equal size. Lack of sliding friction between nut and screw lends itself to extended lifespan of the screw assembly (especially in no-backlash systems), reducing downtime for maintenance, part replacement and decreasing demand for lubrication. This combined with overall performance benefit and reduced power requirements may offset the initial costs of using Ball Screws.
