The FAG HC71908-E-T-P4S-UL is a high-precision hybrid spindle bearing designed for demanding high-speed applications. Featuring a 40 mm bore, 62 mm outer diameter, and 12 mm width, this single-row angular contact ball bearing incorporates ceramic balls (hybrid design) for reduced friction, higher stiffness, and extended service life. The 'E' denotes a 25° contact angle, 'T' indicates a phenolic resin cage, and 'P4S' signifies super precision (P4 with enhanced running accuracy). 'UL' specifies universal arrangement for light preload, allowing for flexible mounting configurations. Ideal for machine tool spindles and other precision rotating equipment.
