    • Finished Shaft Ends Precision Ball Screw Features To meet the space-saving requirement, this type of Ball Screw has a standardized screw shaft and a ball screw nut. The ends of the screw shaft are standardized to t the corresponding support unit. The shaft support method with models BNK0401, 0501 and 0601 is “ xed-free,” while other models use the “ xed-supported” method with the shaft directly coupled with the motor. Screw shafts and nuts are compactly designed. 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-accuracy feed mechanism can easily be achieved. [Contamination Protection and Lubrication] Each ball screw nut contains a right amount of grease. In addition, the ball nuts of model BNK0802 or higher contain a labyrinth seal (with models BNK1510, BNK1520, BNK1616, BNK2020 and BNK2520, the end cap also serves as a labyrinth seal). When foreign material may enter the screw nut, it is necessary to use a dust-prevention device (e.g., bellows) to completely protect the screw shaft. Types and Features Model BNK Speci cation Table⇒A15-132 Ball Screw For this model, screw shafts with a diameter 4 to 25 mm and a lead 1 to 20 mm are available as the standard. A15-129
