Ball Screw Installation
In order to improve the axial rigidity, the screw support usually uses a bearing combination with thrust bearing as the main component. Only when the axial load is very small, the radial thrust bearing is used.

FSC Miniature Ball Screw Working Principle
Arc-shaped spiral grooves are ground on the lead screw and the nut. The two arc-shaped spiral grooves are matched to form a spiral raceway, and balls are installed in the raceway.
