A ball screw converts rotary motion into linear motion with high efficiency and low friction, using recirculating ball bearings. It is used in CNC machines and automation equipment for precise positioning.
Common materials include bearing steel, alloy steel, and stainless steel. The choice depends on load requirements, environmental conditions, and corrosion resistance needs.
Accuracy grades range from C3 (high precision) to C7 (general use), as per ISO 3408. The required grade depends on the application's positioning accuracy demands.
Always confirm model-specific values such as diameter, lead, load ratings, and standards with the legal manufacturer or supplier, as the listed ranges are reference values only.
