Description

Ball Screws

Ball screw assemblies are made up of a leading screw as well as the nut, with helical grooves that match. Balls slide between these grooves, ensuring an interface between the screw and screw. Recirculating bearings allow equipment to run efficiently, with high dynamic and static load ratings.

We carry ball screw models that come in various designs and materials that include Low carbon steels and high-carbon alloy steels, in both metric and standard sizes, as well as various kinds of stainless steel.

Ball screws from our range provide linear motion solutions to various industries, including construction transportation, heavy lifting, medical, marine food packaging, and energy.

Features of Ball Screw Pairs

Ball screw pairs are mechanical devices used to convert rotary motion into linear motion, or vice versa. They consist of two main components: a screw and a nut. Here are the key features of ball screw pairs:

  1. Screw: The screw is a threaded shaft with helical grooves that run along its length. It typically has a high-precision, hardened surface to reduce wear and ensure smooth operation. The screw can have different thread profiles, such as a square or a triangular thread.
  2. Nut: The nut is a component that engages with the screw's threads. It contains matching grooves or channels that accommodate a set of ball bearings. The nut is usually made of a material with low friction, such as bronze or plastic, to minimize resistance during motion.
  3. Ball Bearings: Ball screw pairs utilize ball bearings to reduce friction and facilitate smooth movement. The ball bearings are positioned between the grooves of the screw and nut, allowing the screw to rotate within the nut while minimizing frictional losses.
  4. Efficiency: Ball screw pairs are known for their high mechanical efficiency. The rolling motion of the ball bearings between the screw and nut results in reduced friction compared to other types of screw mechanisms, such as lead screws. This efficiency allows for more precise and efficient linear motion.
  5. Precision: Ball screw pairs offer excellent positional accuracy and repeatability. The rolling contact between the balls and the screw's grooves reduces backlash and ensures precise linear motion. This makes ball screw pairs ideal for applications requiring high precision, such as CNC machines, robotics, and aerospace systems.

Overall, ball screw pairs are highly efficient, precise, and reliable mechanisms for converting rotary motion into linear motion. They find widespread use in industries such as manufacturing, automation, robotics, and aerospace, where precise and efficient linear motion is crucial.
