High-precision ceramic bearings for automobiles
Achieving high durability even in harsh environments.
In the automotive industry, components with high durability that can withstand vibrations and temperature changes during operation are required. Particularly for critical parts such as engines and transmissions, the performance of bearings is a crucial factor that affects product lifespan. Metal bearings are prone to wear and seizure, which may necessitate replacement. Our high-precision ceramic bearings excel in wear resistance and impact resistance, ensuring stable operation over an extended period. 【Application Scenarios】 - Engine - Transmission - Cooling System 【Benefits of Implementation】 - Increased product lifespan - Reduced maintenance costs - High reliability assurance
basic information
**Features** - High precision processing: Dimensional accuracy ±0.3μm, surface roughness Ra 0.03μm or less - Wear resistance and impact resistance: Reduces 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 nurtures "people" through manufacturing, creates "valuable products," and contributes to a "rich future." 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 from process design to processing, assembly, and functional testing, along with the unique development of our own processing machines.
