This spindle bearing is a single-row angular contact type with a contact angle of 15°, 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 0.408 kg. It features a T cage and restricted tolerances, matching the P4S accuracy class. No sealing is fitted on this bearing. The restricted tolerances and P4S accuracy class allow precise axial and radial positioning when the bearing is set up in pairs or sets, maintaining consistent preload across the arrangement. The absence of sealing means external lubrication and protection must be provided by the housing design. The T cage supports stable roller guidance at the specified contact angle, suiting applications where paired or set mounting under controlled preload is required.
