High-precision ceramic bearings (for water-cooled pumps and data center equipment)
High precision × High durability. The new standard for cooling devices.
The ceramic bearings provided by Citizen Fine Device are next-generation bearings that combine lightweight, high wear resistance, and high precision as an alternative to metal bearings. In addition to applications in water-cooled pumps, they have recently been adopted in cooling fans for data center equipment. Features: - High precision machining: Dimensional accuracy ±0.3μm, surface roughness Ra 0.03μm or less - Wear 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: Minimal friction noise, contributing to a quiet design - SDGs compliance: Significant reduction in processes through near-net shaping, achieving low costs
