This spindle bearing carries a 25° contact angle and is designed for mounting in matched pairs or sets, with a bore diameter of 15.0 mm, an outside diameter of 28.0 mm, and a width of 7.0 mm. Net mass is 0.023 kg. The bearing is fitted with non-contact lip seals on both sides and uses a T cage. Manufacturing is held to restricted tolerances, corresponding to P4S accuracy class. The 25° contact angle combined with restricted tolerances and paired/set arrangement allows the bearing to handle combined loads while maintaining running accuracy at elevated speeds. The non-contact lip seals limit friction and heat generation while still restricting contamination ingress, which supports the tight tolerance requirements of this design. The T cage and pair/set matching (P4S, UL designation) require correct axial preload and mounting orientation to maintain the intended stiffness and accuracy of the bearing arrangement.
