Precision Ball Design：The balls of the 7602 series ball screw bearings are made of high-quality steel and finely ground, with precise dimensions and smooth surfaces. This ensures good contact with the screw and nut raceways, effectively reducing friction resistance and enabling efficient and smooth transmission.
Reinforced Screw and Nut：The screw has high-strength and high-precision threads. Through optimized processing techniques, the shape accuracy and surface quality of the threads are guaranteed, allowing it to stably transmit axial forces. The nut features a special structural design, fitting closely with the balls. It can accurately guide the cyclic movement of the balls and bear relatively large radial loads.
Reliable Reverse Device：Equipped with a reliable reverse device, commonly in the form of a 插管式 or end cap type, it ensures the smooth cyclic reciprocating movement of the balls within the raceway composed of the screw and nut, preventing ball jamming and maintaining the continuity of transmission.
High-precision Transmission：The precise cooperation of all components enables extremely small axial clearances and provides ultra-high positioning accuracy. It is widely used in equipment with stringent precision requirements, such as CNC machine tools and precision measuring instruments, ensuring the accuracy of machining and measurement.
High-rigid Load-bearing：Thanks to the reinforced screw and nut structures and the reasonable ball layout, it has excellent axial and certain radial load-bearing capacities. It can stably support working parts and meet the requirements of heavy-duty working conditions, enhancing the stability of equipment operation.
High-efficiency and Energy-saving：The low-friction ball transmission mechanism, compared with traditional screw-nut pairs, can significantly reduce energy consumption, effectively lowering the energy consumption of equipment in long-term operation and improving energy utilization efficiency.

Application

The bearings can be used in the following industries

Machine Tool Manufacturing：It is a key transmission component of various CNC machine tools, such as machining centers and CNC lathes. It achieves precise tool feeding and workpiece positioning, ensuring the machining of high-precision parts.
Automation Equipment：In industrial robots and the robotic arms of automated production lines, it ensures the precise, fast, and stable movement of moving parts, improving production efficiency and product quality.
Precision Instruments：Used in precision instruments such as coordinate measuring machines and microscope focus adjustment mechanisms, it helps achieve high-precision manipulation in the microscopic field, meeting the requirements of scientific research and detection.
