This spindle bearing carries a 25° contact angle and is designed for adjusted mounting in pairs or sets, with restricted tolerances suited to precision applications. Bore diameter is 65.0 mm, outside diameter 90.0 mm, width 13.0 mm, and net mass is 199.78 g. The cage is designation T, and the bearing is supplied without sealing. The restricted tolerance class combined with the 25° contact angle allows this bearing to handle combined loads while maintaining running accuracy at higher speeds when mounted in pairs or sets, as intended by the B719..-E design. Since sealing is not fitted, external lubrication and contamination control must be arranged separately, and the open design keeps radial space free for the fitted cage and rolling elements. The T cage supports stable guidance of the rolling elements under the paired mounting conditions this bearing is built for.
