This spindle bearing carries a bore diameter of 130.0 mm, outside diameter of 200.0 mm, and width of 33.0 mm, with a net mass of 3.517 kg. It is built with a contact angle of 15° and a T-type cage, matched for mounting in pairs or sets under restricted tolerances (P4S). The limiting speed is rated at 15000.0 1/min, and sealing is provided by non-contact lip seals on both sides (2RSD). The 15° contact angle combined with restricted tolerances and paired/set adjustment allows this bearing to run true and maintain consistent preload when mounted as specified, which is essential for stable operation at the stated limiting speed. The non-contact lip seals protect the internals from contamination without adding frictional drag, keeping heat generation low, while the T-type cage supports smooth rolling element guidance suited to sustained high-speed rotation.
