The FAG HCS71912-C-T-P4S-UL is a high-precision hybrid spindle bearing, an angular contact ball bearing designed for demanding high-speed applications. It features a 60mm inner diameter, 95mm outer diameter, and 18mm width. This bearing incorporates ceramic balls (silicon nitride - Si3N4) for reduced friction, higher stiffness, and improved performance at extreme speeds, combined with steel rings. It has a 15° contact angle (C), light preload (T), and P4S (SP) tolerance class, making it universally suitable for paired mounting (UL). Ideal for machine tool spindles and other precision rotating equipment requiring exceptional reliability and speed.
