1. High precision, low operating noise, stable and durable, easy installation and maintenance.2. High positioning accuracy and more precise, high rigidity, wear resistance and high load-bearing capacity.3. Suitable for machining centers, manufacturing equipment, machine tools, mechanical equipment, transmission equipment.Package includes:1PC 2505 right-hand screw + double nut + BKBF20+DSG25H+XB40*65Description:A. Ball Screw AssembliesA ball screw assembly consists of a screw and a nut, each with matching spiral grooves between which the balls roll, providing the only contact between the nut and the screw. As the screw or nut rotates, the balls are deflected by the deflector into the ball return system of the nut, where they travel along a continuous path through the return system to the other end of the ball nut. The balls then exit from the ball return system and enter the ball screw and nut thread raceways, circulating continuously in a closed loop.B. Ball Nut AssembliesThe ball nut determines the load and life of the ball screw assembly. The ratio of the number of threads in the ball nut circuit to the number of threads on the ball screw determines the extent to which the ball nut will reach fatigue failure (wear) sooner than the ball screw.

• 1. Low friction, low operating noise, long service life, fast movement, low friction
• 2. No stick-slip effect, less heat, low drive power, large axial force per unit volume of ball screw
• 3. Can be used for CNC machine tools, DIY machine tools and factory automation equipment, etc.
