This spindle bearing carries a 25° contact angle and is designed for arrangement in pairs or sets under a fixed axial preload. Bore diameter is 55.0 mm, outside diameter 80.0 mm, width 13.0 mm, with a net mass of 174.2 g. The bearing runs on a T-type cage and is supplied without sealing. Manufactured to restricted (P4S) tolerances, it holds precise running accuracy under adjusted mounting conditions. The open design without sealing requires external protection from contamination and demands a suitable lubrication method to maintain the tight internal clearances characteristic of this precision class.
