This spindle bearing carries a bore diameter of 10.0 mm, outside diameter of 22.0 mm, and width of 6.0 mm, with a net mass of 10.0 g. It is built with a contact angle α = 25° and a fabric-reinforced phenolic resin cage (T), designed for adjustment in pairs or sets. The bearing is supplied without sealing and to restricted (P4S) tolerances. The 25° contact angle combined with restricted tolerances allows this bearing to handle combined loads while maintaining running accuracy at high speeds. Since it is intended for use in pairs or sets, axial clearance can be set according to the required rigidity and preload. The absence of sealing means lubrication and contamination protection must be provided externally, and the T cage supports smooth operation under the elevated speed conditions typical for this bearing series.
