A Ball Screw Support, also commonly known as a Ball Screw Support Unit or End Support Bearing, is a highly specialized bearing assembly designed to rigidly support the ends of a ball screw shaft. It is a critical component within the Linear Actuation Systems category, where its primary function is to secure the ball screw and manage the high axial (thrust) and radial loads generated during operation.

 

The defining characteristic of a high-quality fixed-end ball screw support unit is its use of high-rigidity, preloaded angular contact bearings. This specialized assembly provides unparalleled stability to the ball screw shaft.
Advantages of using these specialized support units include:
High Axial Rigidity: The bearings are often mounted in a back-to-back (DB) or face-to-face (DF) configuration and are precisely preloaded during manufacturing. This eliminates any internal clearance (backlash) in the support unit, ensuring the ball screw is held absolutely firm in the axial direction, which is vital for high-precision positioning.
Simplified Installation: The support unit is typically delivered as a fully assembled, pre-lubricated, and sealed module. This significantly simplifies machine assembly compared to mounting individual angular contact bearings and setting the preload manually.
High Precision: The housing is precision-machined to ensure the mounted bearings are perfectly aligned, minimizing shaft run-out (wobble) and maximizing the life of the entire ball screw system.
Protection: The unit is sealed to protect the sensitive internal bearings from contaminants and to retain the necessary high-performance grease.

A fixed-end Ball Screw Support Unit (the most complex type) is an integrated assembly composed of several key Component Parts:
Housing (Support Block): A rigid, precision-machined cast iron or aluminum block with a flat mounting surface and a central bore for the shaft.
Angular Contact Ball Bearings: Two or more precisely matched, high-precision ball bearings arranged to support combined radial and high axial loads. These are the main load-bearing components.
Seals and End Covers: Labyrinth or contact seals and end covers that protect the internal bearings and provide a clean external housing.
Locknut/Spacer: A precision locknut is used internally or externally to clamp the bearing set onto the ball screw shaft, often maintaining the preloaded condition.
