The FAG HC7008-E-T-P4S-UL is a high-precision hybrid spindle bearing, specifically an angular contact ball bearing designed for demanding applications. It features ceramic balls (hybrid design) for enhanced performance, higher speed capabilities, and reduced friction compared to traditional steel ball bearings. With a 25° contact angle (E), it is suitable for applications requiring high axial and radial rigidity. The 'T' indicates a PEEK cage, and 'P4S' denotes a special precision class, exceeding P4 (ABEC 7). The 'UL' signifies universal arrangement for paired mounting with light preload. This bearing has a 40 mm bore diameter, 68 mm outer diameter, and 15 mm width, making it ideal for machine tool spindles and other high-speed, high-precision rotating equipment.
