Angular Contact Ceramic Ball Bearing H7004C-2RZ HQ1

SKU / Model: TQ-BRG-H7004C-2RZ-HQ1

The Angular Contact Ceramic Ball Bearing H7004C-2RZ HQ1 represents the pinnacle of high-speed mechanical rotation technology, meticulously engineered for demanding CNC spindle applications that dictate extreme positional precision and minimal thermal friction. Utilizing premium silicon nitride (Si3N4) ceramic balls paired with high-grade steel raceways, this hybrid ceramic bearing yields substantial advantages over standard steel elements, including lower centripetal forces, drastically reduced heat generation, and superior wear resistance under rigorous operational cycles. Featuring an optimized 15-degree contact angle (C profile), it facilitates fluid management of simultaneous radial and axial vector forces, preserving near-zero runout tolerances at an extreme grease-lubricated limiting speed of 61,900 r/min.
