The FAG B71915-E-2RSD-T-P4S-UM is a high-precision, sealed spindle bearing designed for applications requiring extreme accuracy and rigidity. This angular contact ball bearing features ceramic balls (hybrid design) for enhanced performance, reduced friction, and higher speed capabilities. It is sealed on both sides (2RSD) to protect against contaminants and retain lubrication, ensuring a longer service life. The T suffix indicates a textile laminate cage, and P4S denotes a super-precision tolerance class, suitable for machine tool spindles and other high-speed, high-precision machinery. The UM designation signifies universal matching for paired installation.
