Precise angular positioning of the shaft under combined loads is achieved through a 25° contact angle, matching this spindle bearing for mounting in matched pairs or sets with adjusted preload. Bore diameter is 30.0 mm, outside diameter 55.0 mm, width 13.0 mm, net mass 109.17 g, with a T cage and restricted tolerances (P4S) for accurate running. Non-contact lip seals are fitted on both sides (2RSD). The restricted tolerance class and the fixed 25° contact angle make this spindle bearing suitable for arrangements requiring defined stiffness and running accuracy when mounted as pairs or sets, since preload and orientation must be maintained across the set. The non-contact lip seals limit friction and heat generation while still restricting ingress of contaminants, and the T cage supports stable guidance of the rolling elements at the working speeds permitted by the P4S tolerance grade.
