This spindle bearing is a single-row angular contact type with a 15° contact angle, designed for adjusted mounting in pairs or sets. Bore diameter is 45.0 mm, outside diameter 85.0 mm, width 19.0 mm, and net mass 0.418 kg. The bearing features non-contact lip seals on both sides and a T-type cage, with restricted tolerances applied to bore, outside diameter and width for precise fit and running accuracy. The 15° contact angle allows combined radial and axial load support with high stiffness, suitable for arrangements requiring precise axial positioning through matched pairs or sets. The restricted tolerance class supports tight-fit assembly and consistent preload behavior, while the non-contact seal design limits friction and heat generation, permitting sustained operation at elevated speeds compared to contact-seal variants. The T cage contributes to stable ball guidance under these conditions.
