Ball screw components undergo heat treatment at some point in the manufacturing process to strengthen the material. %PDF-1.5 The proper lubricant and packaging materials can significantly reduce the negative effects of long-term storage, including oxidation and rust. JIS B 1192 defines ball screw accuracy of the precision ball screws.
