Shuntai Precision Machinery has the answer for you: The life of the ball screw can be calculated by the service life formula. The service life of the ball screw is usually based on reliability, and the reliability is generally 90%. The following is the calculation formula for the service life of the ball screw: L= (C/P) * (10^6) in: L is the service life of the ball screw (number of strokes); C is the basic dynamic load rating (N); P is the actual working load (N). The basic dynamic load rating of a ball screw is usually provided by the manufacturer and refers to the maximum load that the ball screw can withstand under ideal conditions. Actual operating load refers to the load exerted on the ball screw in actual applications. The service life formula assumes the following conditions: - The ball screw travels at a constant speed; - The load is constant and perpendicular to the axial direction of the ball screw; - The temperatures of the ball screw and load-bearing parts are maintained within the appropriate operating range; - Proper lubrication conditions. It is important to note that this formula is only used as a preliminary estimate of ball screw life. In practical applications, other factors should also be considered, such as the degree of pollution of the working environment, impact load and vibration, operating temperature, etc. In addition, the service life of a ball screw is also related to factors such as its manufacturing quality, lubrication and maintenance. It is recommended to consult the ball screw manufacturer or engineer in your specific application for more accurate life predictions and recommendations.
