7005 CD/P4ADBA Bearing Product Overview & Core Advantages
The 7005 CD/P4ADBA is a precision duplex angular contact ball bearing designed for applications requiring exceptional rotational accuracy and rigidity. This back-to-back (DB) matched pair configuration provides superior stability and is optimized to handle combined loads—simultaneously supporting significant radial and axial forces. Manufactured to the stringent P4A tolerance class, it delivers ultra-precise running characteristics, making it ideal for high-performance machinery where high rigidity and minimal runout are critical.
7005 CD/P4ADBA Bearing Model Code Explained, Specifications & Naming Convention
The model number 7005 CD/P4ADBA provides detailed technical specifications:
- 7005: Standard bearing series designation (25mm bore, 47mm OD).
- C: Indicates a 15° contact angle, optimized for high-speed operation and axial load capacity.
- D: Denotes a duplex back-to-back (DB) arrangement of two matched bearings.
- P4A: Specifies the ultra-precision tolerance class, exceeding ABEC 7 standards for exceptional dimensional and running accuracy.
- DB: Confirms the back-to-back mounting configuration.
- A: Indicates Extra Light (Class A) preload, minimizing deflection while maintaining smooth, low-friction operation.
7005 CD/P4ADBA Bearing Structural Features & Performance Benefits
- High Rigidity & Stability: The duplex back-to-back design creates a wide, rigid support system that effectively resists moment loads and shaft deflection, ensuring precise alignment under combined loads.
- Superior Load Capacity: With a 15° contact angle and optimized internal geometry, this bearing efficiently handles both radial and substantial bidirectional axial loads.
- High-Speed Capability: The lightweight phenolic resin cage and precision-ground chrome steel components enable stable operation at high rotational speeds, with a limiting speed of 103,000 rpm.
- Precision Performance: Manufactured to P4A tolerance class with tight dimensional controls (bore/OD tolerance: -0.004mm to 0), this bearing guarantees minimal vibration and exceptional running accuracy for demanding applications.
