Standard bearings generated unacceptable vibration levels (over 10 μm), affecting product accuracy. Shuguang responded by designing a custom deep groove bearing series using AISI 316L stainless steel, optimized for minimal internal clearance and enhanced balance. The solution included integration with automatic oil clearance measuring equipment and vibration testing machines during final inspection. Post-implementation, the robot arm’s positioning error dropped from 0.05mm to 0.008mm, and vibration levels were reduced to below 3 μm—well within the industry’s strictest standards. This project highlighted Shuguang’s R&D strength, with its team of five technical experts and 13 quality inspectors working collaboratively to deliver a product that exceeded customer expectations. Moreover, the company’s investment in two additional fully automatic 100% inspection lines (planned for October 2022) ensures scalability and consistency for future custom orders. Today, Shuguang’s bearings are exported to over 100 countries, serving sectors ranging from aerospace to marine engineering, proving that their custom capabilities are not only technically sound but commercially viable on a global scale.
