This spindle bearing carries a 25° contact angle and is manufactured to restricted tolerances (P4S), suiting it for precise axial and radial location under adjusted mounting. Bore diameter is 35.0 mm, outside diameter 55.0 mm, width 10.0 mm, and net mass is 76.53 g. The cage is designated T, and the bearing is supplied without sealing. Being matched in pairs or sets (designation UL), it allows for a defined preload to be set during mounting, which is required to achieve the stiffness and running accuracy associated with the P4S tolerance class. The absence of seals means lubrication and contamination protection must be provided externally by the housing design. The 25° contact angle gives the bearing a balanced capacity to carry combined axial and radial loads while running at the speeds typical of spindle applications.
