Ball screw selection often involves overlooked details that affect both equipment performance and lifespan. This article reveals three common misconceptions and tips for avoiding these pitfalls, teaching you how to choose the right screw and avoid common mistakes.   Ball screws are frequently used in high-precision transmission and control applications, but many users fall into several common traps when selecting them.   Misconception 1: Focusing only on accuracy precision, ignoring load   Users unfamiliar with ball screws often prioritize accuracy grade while neglecting the actual load requirements in operation. For example, a high-precision C3-grade ball screw used in heavy-duty equipment may fail quickly due to its inability to withstand heavy loads. In a real-world case, a manufacturer's C3-grade ball screw failed after only one month under heavy-duty conditions. Misconception 2: Larger lead means faster speed   Many users believe that a larger lead means faster speed. In reality, the lead must be matched to the motor speed. Setting the lead too large not only limits speed improvement but also easily leads to problems such as vibration and inaccurate positioning. Myth 3: The Operating Components of a Ball Screw   If the installation environment of a ball screw is dusty or humid without protective measures, the lifespan of the ball screw will be significantly reduced. In harsh environments, without effective sealing and lubrication, the lifespan of the ball screw can be reduced by more than half.   Summary:   When purchasing ball screws, it is essential to compare the following five core parameters: - Screw diameter - Lead - Accuracy class - Rated load - Maximum speed   It is recommended to create a selection comparison table, comparing each parameter one by one, and comprehensively considering actual working conditions to ensure a worry-free selection.
