This spindle bearing is a single row angular contact type with a 15° contact angle, bore diameter 20.0 mm, outside diameter 42.0 mm, and width 12.0 mm, weighing 0.08 kg. It is fitted with a T cage and non-contact lip seals on both sides (2RSD), and is manufactured to restricted tolerances for precise, adjusted mounting in pairs or sets. The permissible limiting speed reaches 80000 1/min. The 15° contact angle and restricted tolerance grade make this bearing suitable for arrangements requiring precise axial and radial guidance combined with high running accuracy. The non-contact lip seals on both sides limit friction and heat generation, supporting stable operation at the specified high limiting speed. Being supplied for use in pairs or sets, it allows for defined preload and stiffness setting appropriate to the mounting requirements.
