This spindle bearing is designed for precision angular contact applications, with a contact angle α = 15° and restricted tolerances for accurate shaft positioning. The bore diameter is 160.0 mm, the outside diameter is 220.0 mm, and the width is 28.0 mm, giving the mounting envelope for the housing and shaft seat. The cage is made of material T, and the bearing has a net mass of 2.587 kg. It is supplied without sealing, so protection from contamination must be provided externally. As a B719..-C type, this bearing is adjusted and intended for mounting in pairs or sets, allowing controlled preload to be set during assembly. The restricted tolerance class supports precise axial and radial positioning of the shaft, which is relevant where rotational accuracy and stiffness of the bearing arrangement must be maintained. Since no sealing is integrated, lubrication and contamination control depend on the surrounding housing design.
