71800 ACD/P4DFBVT162F2 Bearing Product Overview & Core Advantages
The 71800 ACD/P4DFBVT162F2 is a precision duplex angular contact ball bearing designed for applications requiring exceptional rotational accuracy and rigidity. This matched arrangement of two bearings in a face-to-face (DF) configuration provides superior support for combined loads, handling significant radial and bidirectional axial forces simultaneously. Manufactured to P4 tolerance class with a light preload (Class B), it ensures minimal runout and stable performance in high-speed and high-precision environments. The compact design, with a 10 mm bore and 19 mm outside diameter, makes it ideal for space-constrained applications.

71800 ACD/P4DFBVT162F2 Bearing Structural Features & Performance Benefits
Optimized Internal Geometry: The 25° contact angle is engineered to support high axial loads from both directions, making it exceptionally capable for combined load conditions.
High Rigidity & Stability: The duplex face-to-face (DF) pairing creates a highly rigid bearing system that effectively resists moment loads, ensuring precise shaft positioning and minimal deflection under operational stresses.
High-Speed Capability: The lightweight phenolic cage (VT162) minimizes centrifugal forces and ensures stable guidance of the 12 precision chrome steel balls, contributing to the high limiting speed of 95,000 rpm. The open seal design reduces friction and heat generation.
Precision Performance: Manufactured to ABEC 7/P4 tolerance standards with strict bore, OD, and width tolerances, this bearing guarantees exceptional running accuracy, low vibration, and consistent performance in demanding applications.
