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 30.0 mm, outside diameter 47.0 mm, width 9.0 mm, and net mass 50.1 g. The cage is made in version T, and the bearing has restricted tolerances, without sealing. The 15° contact angle allows the bearing to carry combined radial and axial loads while supporting high-speed operation typical of spindle applications. Restricted tolerances place this bearing in a precision class suitable for arrangements requiring low running inaccuracy. As it is supplied without sealing, external protection and lubrication arrangement must be provided by the housing design. Pairing or set configuration (denoted by C) allows correct preload to be achieved when mounted back-to-back, face-to-face, or in tandem, depending on the intended stiffness and load direction.
