To meet space-saving requirements, this type of ball screw has a standardized screw shaft and a ball screw nut. The ends of the screw shaft are standardized to fit the corresponding support unit. The shaft support method with models BNK0401, BNK0501, and BNK0601 is "fixed-free," while other models use the "fixed-supported" method with the shaft directly coupled with the motor.
Screw shafts and nuts are designed to be compactly. When a support unit and a nut bracket are combined with a ball screw, the assembly can be mounted on your machine as it is. Thus, a high-precision feed mechanism can easily be achieved.
