2505 single ball screw nut ball screw model diagram is made with high precision mechanical transmission components screw, nut, ball, seals and other parts of the tools, machinery and precision machinery transmission components most commonly used, and its main function is to convert rotary motion into linear motion or torque into axial force over and over again, little vibration, low noise, smooth operation, high reliability, long life, while both high-precision, reversible and high efficiency characteristics. Ball is the rotary motion into linear motion, or linear motion into rotary motion of the desired product. Ball screw ball rolling motion, starting torque is extremely small, no crawling as prone to sliding motion, creep phenomenon, it is possible to ensure accurate micro feed. Other hand, due to ball screw high efficiency, low friction, low fever, which can perform high-speed feed.
