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. To extend service life within harsh woodworking router or high-velocity metal milling environments, the assembly is outfitted with double non-contact rubber seals (2RZ) that retain premium high-speed synthetic grease while barring entry to fine dust, airborne particulates, and liquid coolant spray. The HQ1 designation guarantees precision-matched engineering balancing, making this bearing the definitive solution for high-frequency motorized spindle overhauls requiring long-term operational consistency.
Technical Core: Rated for industrial-grade output, maximum rotational velocity of high-performance, operating voltage of 220V/380V, with Water/Air Cooled thermal stabilization.
