Frequently asked questions

Ball screws are mechanical components used for the transmission of rotary motion. They consist of a screw with a series of balls arranged between the screw and the raceway and offer low resistance to movement and a high load capacity. Ball screws are widely used in industrial applications and automation.

Choosing the right ball screw is crucial to ensuring optimal performance in mechanical systems. You have to consider several factors when making your selection. Carefully evaluate the applied load, making sure that you choose a ball screw with a load capacity that meets the system's requirements. Choosing the correct ball screw meetng the required rotation speed is a critical aspect of the design that will ensure reliable performance over the life of the ball screw. The required lead precision is another important aspect to consider. Choose a ball screw with a precision class that meets your system's requirements. Don't forget to also consider the environment in which the screw will be used, opting for a solution with good protection against dust, dirt or moisture.

The various types of ball screws differ in design and application. The main differences lie in the configuration of the raceways and the drive modes. There are single, multiple, high-speed, miniature, backlash-free and direct drive ball screws. The choice depends on system and application requirements. Carefully consider the specifications and characteristics of each type of ball screw to ensure you get the best solution for your needs. Evaluate the load, speed, accuracy and dimensions required. Consult experts and specialised suppliers for personalized advice. Choosing the right type of ball screw will affect the performance and reliability of your mechanical system.
