The HFH HCS7009CTP4SUL is a genuine HFH high-precision hybrid ceramic angular contact ball bearing, specifically engineered for demanding spindle applications requiring exceptional speed, rigidity, and accuracy. This single-row bearing features a 45mm inner diameter, 68mm outer diameter, and 12mm width. Its 'C' designation indicates a 15-degree contact angle, while the 'T' signifies a robust phenolic resin cage. With a P4S precision class, this bearing ensures superior running accuracy. The 'UL' suffix denotes a universal arrangement with light preload, allowing for versatile mounting configurations. The ceramic balls (implied by 'HCS') contribute to higher rotational speeds, reduced friction, and extended service life in high-performance machinery.
