This spindle bearing carries a 25° contact angle and is built for high-precision, high-speed applications requiring accurate axial and radial guidance. Bore diameter is 70.0 mm, outside diameter 125.0 mm, width 24.0 mm, and net mass 1.085 kg. The cage is designated T, and the bearing is supplied without sealing. It is manufactured to restricted tolerances (P4S) and matched for mounting in pairs or sets, denoted by the UL suffix. The universal matching design allows flexible arrangement in back-to-back, face-to-face, or tandem configurations, which suits shafts requiring stiff, defined preload and stable running accuracy. As the bearing has no integrated sealing, external sealing and a controlled lubrication system must be provided by the housing design. The T cage supports stable cage guidance at elevated speeds, consistent with the restricted P4S tolerance class intended for precise shaft positioning under adjusted mounting conditions.
