The INA-FAG B7018-E-T-P4S-DUL is a high-precision spindle bearing designed for demanding applications requiring extreme accuracy and rigidity. This FAG bearing features a 90mm bore diameter, 140mm outer diameter, and 24mm width. It is manufactured to P4S precision class, indicating very high running accuracy. The 'E' suffix denotes an optimized internal design, 'T' indicates ceramic balls (hybrid bearing), and 'P4S' refers to the precision class. The 'DU' signifies a universal design for paired mounting, allowing for various arrangements (tandem, back-to-back, face-to-face) with defined preload. The 'L' indicates light preload. This bearing is ideal for machine tool spindles and other high-speed, high-precision rotating equipment.
