This spindle bearing is designed for precise shaft positioning under high rotational speeds, with a 15° contact angle for combined radial and axial load handling. Bore diameter is 80.0 mm, outside diameter 125.0 mm, width 22.0 mm, and net mass 0.886 kg. The limiting speed reaches 24000 1/min, supported by a T-type cage construction. The bearing carries restricted tolerances under P4S accuracy class and is matched with C-type internal geometry for adjusted mounting. Being supplied without sealing, the bearing requires external contamination protection and a defined lubrication method suited to high-speed operation, typically oil lubrication for effective heat dissipation. Its adjusted design allows use in pairs or sets, with the restricted tolerance class (P4S) and defined internal clearance (C) ensuring accurate axial and radial positioning under high-speed rotation. The UL designation indicates suitability for oil lubrication systems, consistent with the demands of precision spindle applications requiring tight running accuracy and controlled preload.
