The FAG B71906-C-T-P4A-UM is a high-precision single row angular contact ball bearing designed for demanding spindle applications. Featuring a 30 mm bore diameter, 55 mm outer diameter, and 13 mm width, this bearing is engineered for high speed and accuracy. It incorporates ceramic balls (suffix T) for reduced friction and increased stiffness, a 15° contact angle (suffix C) for optimized axial and radial load capacity, and P4A precision class for superior running accuracy. The UM suffix indicates universal matching for easy installation in sets. This FAG spindle bearing is ideal for machine tool spindles and other high-precision rotating equipment.
