This type of ball screw is mass produced by cutting standardized screw shafts of precision ball screws to fixed lengths. The shaft ends can easily be modified with additional machining.
To meet various intended purposes, THK offers several ball screw models with different types of nuts: the single-nut type (Model BNF), the offset preload-nut type (Model BIF), and miniature ball screws (models MDK and MBF).
