This spindle bearing carries a 25° contact angle and is designed for precise axial and radial positioning under high-speed conditions. Bore diameter is 85.0 mm, outside diameter 130.0 mm, width 22.0 mm, and net mass 0.881 kg. The cage is executed in version T, and the bearing is supplied without sealing, matched for mounting in pairs or sets under restricted tolerances (P4S). The restricted tolerance class ensures tight running accuracy and consistent preload when bearings are paired, which supports stable shaft guidance and reduced radial play under load. As the bearing is unsealed, external lubrication and protection must be provided by the housing design. The absence of integrated sealing keeps axial space free, which is relevant where the paired or set arrangement requires precise face-to-face contact for correct preload setting.
