The FAG B7008-E-T-P4S-DBL is a high-precision spindle bearing set manufactured by FAG (part of the Schaeffler Group). This duplex set is configured in a back-to-back (DB) arrangement with a light preload (L), optimized for applications requiring high rotational accuracy and rigidity. It features a 40 mm bore diameter, a 68 mm outer diameter, and a total width of 30 mm for the set. These angular contact ball bearings have a 25° contact angle (E) and belong to the P4S super precision class. The 'T' suffix denotes a phenolic resin cage, making it suitable for high-speed operation in machine tool spindles and other precision machinery.
