This type of ball screw is mass-produced by cutting the standardized screw shafts of precision ball screws to fixed lengths. Additional machining of the shaft ends can easily be performed.
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 the miniature ball screw (Models MDK and MBF).
