This spindle bearing has a 15° contact angle and is designed for precise axial and radial positioning under high-speed rotation. Bore diameter is 12.0 mm, outside diameter 24.0 mm, width 6.0 mm, and net mass 13.0 g. The limiting speed reaches 140000 1/min, supported by a T-type cage that reduces friction and heat generation at high rotational rates. Non-contact lip seals (2RSD) are fitted on both sides, limiting friction losses while keeping contamination out. Manufactured to restricted tolerances (P4S accuracy class) and matched in pairs or sets (C arrangement), this bearing is intended for mounting configurations requiring consistent preload and minimal runout. The combination of tight tolerances, low-friction sealing, and a high limiting speed makes it suitable for applications where rotational accuracy and thermal stability under sustained high-speed operation are critical.
