The FAG HC7004-E-T-P4S-UL is a high-precision hybrid angular contact ball bearing designed for demanding applications such as machine tool spindles. This super-precision bearing features ceramic rolling elements (hybrid design) for enhanced speed capability, reduced friction, and extended service life compared to steel ball bearings. It has a 25° contact angle (E) for high axial and radial rigidity, a textile laminate cage (T), and a P4S precision class. The 'UL' designation indicates a universal design for arrangement in sets with a light preload, ensuring optimal performance in various configurations. Its dimensions are a 20 mm bore, 42 mm outer diameter, and 12 mm width.
