The FAG B7204-C-T-P4S-DFL is a high-precision angular contact ball bearing designed for spindle applications requiring extreme accuracy and rigidity. This single-row bearing features a 20 mm bore diameter, 47 mm outer diameter, and 14 mm width. It has a contact angle of 15 degrees (C), a phenolic resin cage (T), and P4S precision class, indicating very high running accuracy. The 'DFL' suffix suggests a specific preload or arrangement, often used in pairs. Manufactured by FAG (part of Schaeffler Group), it ensures reliable performance in machine tool spindles and other high-speed, high-precision rotating equipment.
