7006 CE/P4ADGA Bearing Product Overview & Core Advantages
The 7006 CE/P4ADGA is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional rotational accuracy and rigidity. Engineered with P4A tolerance class and Extra Light preload (Class A), this bearing delivers superior running precision and minimal vibration. Its Universal Matchable (SU) design allows for flexible mounting in duplex pairs (DB, DF, DT) to optimize stiffness and load distribution. The bearing is pre-lubricated for immediate operation and features a phenolic resin cage for high-speed capability and reduced friction.

7006 CE/P4ADGA Bearing Structural Features & Performance Benefits
Precision Engineering: Manufactured to P4A tolerance class with extremely tight dimensional control (bore/OD tolerance: -0.004mm to 0), ensuring exceptional running accuracy and system stability.
High-Speed Capability: The phenolic resin cage provides excellent strength-to-weight ratio, reducing centrifugal forces and enabling operation at limiting speeds up to 100,500 rpm.
Optimized Load Capacity: With a 15° contact angle and 17 precision balls (6.35mm diameter), the bearing efficiently handles combined radial and axial loads (dynamic rating: 3398 lbf, static rating: 2340 lbf).
Thermal Stability: The phenolic cage and chrome steel construction maintain dimensional stability across the operating temperature range of -30°C to 110°C.
Universal Matching: As an SU-type bearing, it can be paired in any duplex arrangement without selective matching, simplifying installation and inventory management.
