The 7205C-2RZ HQ1 is a premium hybrid angular contact ball bearing engineered for high-performance industrial systems requiring extreme durability and speed. By pairing precision-ground steel rings with aerospace-grade Silicon Nitride (Si3N4) ceramic balls, this bearing achieves a grease-lubricated limiting speed of 30,000 RPM. The 25mm bore and 52mm outside diameter, combined with an 18mm width, provide a robust dynamic load rating of 16.7 KN. Ceramic balls are significantly lighter and harder than steel, which reduces internal heat generation and centrifugal forces at high velocities. This P4 precision grade bearing is the ideal choice for high-speed CNC spindles, aerospace components, and automotive performance engineering where thermal stability, reduced noise, and extended service life are critical requirements.
