The FAG B7021-C-T-P4S-DTL is a high-precision spindle bearing set consisting of two single row angular contact ball bearings arranged in a duplex tandem configuration with light preload (DTL). Designed for demanding applications requiring high running accuracy and rigidity, this bearing set features a 105 mm bore diameter, 160 mm outer diameter, and a combined width of 52 mm (two individual bearings, each 26 mm wide). It has a 15° contact angle (C) and a textile laminate cage (T). The P4S tolerance class ensures superior precision, making it ideal for machine tool spindles and other high-speed, high-accuracy rotating components.
