A recirculating ball screw is a mechanical component used to convert rotational motion into linear motion. It consists of a threaded shaft (screw) with balls that recirculate in a nut along the threaded shaft. The nut has internal grooves that match the thread profile of the screw. When the screw is rotated, the balls roll between the screw and nut, allowing the nut to move along the screw in a linear direction. The rolling contact between the balls and the screw thread enables smooth and efficient transmission of linear movement. The balls in a recirculating ball screw are typically made of hardened steel or other durable materials. They are held within the nut by an internal mechanism (such as a ball return system) that ensures the balls circulate back to the beginning of the nut after reaching the end. The lifetime of a ball screw depends on several factors, including the load applied, the speed of operation, the orientation (horizontal or vertical), and the maintenance and lubrication practices. In general, ball screws are known for their high durability and long service life. Proper lubrication and regular maintenance can help extend the lifetime of a ball screw.

The following issues may arise when using ball screws in large applications: 1. Load and torque limitations: The load and torque bearing capacity of ball screws is limited. In large equipment applications, large loads and torques need to be borne, and ball screws may not be able to meet these requirements. This may lead to overload, deformation or damage to the ball screw. 2. Length limitation: Another important factor for ball screws is length. Longer ball screws are prone to deflection and vibration, which reduces the accuracy and stability of the system. In large applications, if longer strokes are required, other more suitable transmission methods may be required. 3. Accuracy and return error: The accuracy of ball screws is limited by factors such as thread processing and material quality. In large applications, if higher accuracy is required, other higher accuracy transmission methods may need to be considered. In addition, ball screws may have a certain return error when moving in reverse, which may affect the positioning accuracy of the system. 4. Maintenance and life: In large applications, ball screws are usually required to withstand large loads and working pressures, which may cause wear and fatigue of the ball screws. Maintenance and care of ball screws may require more frequent inspections and replacements to ensure system reliability and life. When selecting a transmission method, it is necessary to comprehensively consider factors such as application requirements, load, accuracy, axial stiffness and life, and evaluate whether the ball screw is suitable for a specific large application. In some cases, other transmission methods such as linear guides, gear transmissions or hydraulic transmissions may need to be considered to meet the requirements of large applications.

My suggestion is: if you want a longer service life, it is recommended to repurchase. If you want to repair it, the shipping cost is also an expense. Consider it comprehensively according to the degree of damage. Ball screw is a common mechanical transmission device used to convert rotary motion into linear motion. However, long-term use or improper maintenance may cause the ball screw to be damaged or malfunction. When there is a problem with the ball screw, we face an important decision: should we repair the ball screw or buy a new one? Option 1: Repair the ball screw 1. Economical: Repairing a ball screw is usually cheaper than buying a new one. If the ball screw has only experienced minor failures or wear, repair may be a more economical and reasonable option. Repair may involve replacing damaged parts or making adjustments and lubrication. 2. Time benefit: Repairing a ball screw usually takes less time than buying a new one. Buying a new ball screw involves selecting the right model, waiting for delivery and installation, while repairs can usually solve the problem faster. 3. Environmental considerations: Repairing a ball screw helps reduce waste generation and is in line with the concept of sustainable development. If the problem can be solved by repair, then repurchasing a new ball screw may be a waste of resources. Option 2: Repurchasing a ball screw 1. Severe damage: If the ball screw has suffered serious damage, including breakage or severe wear of key components, repairs may not be able to effectively fix the problem. In this case, purchasing a new ball screw is a more reliable option to ensure the normal operation of the system. 2. Technology update: Ball screw technology is constantly evolving, and a new generation of ball screws may have higher performance and longer service life. Repurchasing a new ball screw can upgrade and improve the system and improve overall performance. 3. Frequent failures: If the ball screw repeatedly fails or works unstably, repairs may only be a temporary solution. Repurchasing a reliable ball screw can avoid frequent repairs and downtime, and improve production efficiency and reliability. Conclusion: When facing a ball screw failure, we can choose whether to repair the ball screw or repurchase a new one according to the actual situation. If the problem is minor and the repair cost is low, repair may be a more cost-effective option. However, for severe damage, frequent failures, or the pursuit of higher performance, repurchasing the ball screw may be a more reliable solution.
