High-precision ceramic bearings for semiconductor manufacturing
High precision × high durability. Bearings that support precise control.
In the semiconductor manufacturing industry, as manufacturing processes become more advanced, precise positioning and control are required. Particularly in areas where fine movements are necessary, such as wafer transport devices and inspection equipment, the accuracy and durability of bearings become crucial factors that influence product quality and yield. In metal bearings, issues such as wear debris generation and vibration can arise, but our high-precision ceramic bearings address these challenges. 【Application Scenarios】 - Wafer transport devices - Precision inspection equipment - Exposure equipment 【Benefits of Implementation】 - Achieves high-precision positioning and stable operation - Reduces the generation of wear debris, enhancing product reliability - Lowers maintenance costs through increased lifespan
basic information
【Features】 - High precision processing: Dimensional accuracy ±0.3μm, surface roughness Ra below 0.03μm - Wear resistance and impact resistance: Suppresses the generation of wear particles and is less prone to deformation from drop impacts - Environmental resistance: Stable operation even in high temperature and high humidity environments - Quiet operation: Low friction noise contributes to a quiet design - SDGs compliance: Significant reduction in processes through near-net shaping, achieving low prices 【Our Strengths】 Citizen Fine Devices leverages the technology cultivated over many years in the field of functional components that require compact precision, high accuracy, and high detail to provide high value-added microdevice products.

The area where Citizen Fine Devices demonstrates its strength is in the realm of functional components that require small size, precision, high accuracy, and high detail. We believe that our mission is to continue providing high-value-added microdevice products by leveraging the unique technologies we have developed over many years. Utilizing metal processing technology rooted in watch manufacturing, we have consistently supplied small, high-precision components to our customers for many years through a fully integrated production line that encompasses process design, machining, assembly, and functional testing, along with the unique development of our own processing machines. Additionally, mass-producing components with high precision and efficiency using brittle materials is also one of our core technologies. By integrating material technology with ultra-precision machining, thin-film technology, and bonding technology, we produce not only high-precision components such as ceramics and quartz but also high-quality functional device products like liquid crystal devices and sensing devices. Continuing to provide high-value-added products to the market is a significant dream for our employees. We will contribute to the creation of new value through manufacturing driven by the challenge spirit of each individual, working towards the realization of that dream.
