71802 ACD/P4DBAVT162F7 Bearing Product Overview & Core Advantages
The 71802 ACD/P4DBAVT162F7 is a precision angular contact ball bearing designed for applications requiring exceptional accuracy and reliability. This duplex back-to-back (DB) matched set excels at handling combined loads, including significant radial loads and thrust loads in both directions. Its extra light preload (Class A) ensures minimal deflection and smooth operation, making it ideal for high-precision, high-speed machinery. The compact dimensions (15 mm bore, 24 mm OD, 10 mm width) and phenolic cage contribute to its superior performance in demanding environments.

71802 ACD/P4DBAVT162F7 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The duplex back-to-back configuration creates a rigid bearing system that effectively handles combined radial and axial loads from both directions. The 25° contact angle optimizes axial load carrying capacity while maintaining excellent radial performance.
Precision Performance: Manufactured to P4 tolerance class with tight dimensional controls (bore/OD tolerance: -0.004mm to 0), this bearing ensures minimal runout and vibration. The extra light preload eliminates internal clearance, providing precise rotational accuracy and reduced deflection under load.
High-Speed Capability: The phenolic cage offers excellent strength-to-weight ratio and smooth operation at high speeds, supporting the impressive limiting speed of 121,000 rpm. The optimized grease lubrication (VT162F7) ensures consistent performance across the operating temperature range of -30°C to 110°C.
Material Excellence: Constructed from chrome steel for both rings and balls, this bearing delivers superior wear resistance and fatigue life. The combination of 17 precision balls (2.381 mm diameter) provides optimal load distribution and smooth operation.
