7006 CEGB/P4A Bearing Product Overview & Core Advantages
The 7006 CEGB/P4A is a single-row angular contact ball bearing designed for high-precision and high-speed applications. Manufactured to the exacting P4A tolerance class, it delivers exceptional running accuracy and dimensional stability. This bearing is universally matchable (SU), allowing for precise preload control when mounted in pairs. Its optimized 15° contact angle provides superior performance under combined radial and axial loads, making it an ideal choice for demanding, high-rigidity systems.
7006 CEGB/P4A Bearing Model Code Explained, Specifications & Naming Convention
The model number 7006 CEGB/P4A is decoded as follows:
- 7006: Standard series designation for a metric angular contact ball bearing with a 30mm bore.
- C: Indicates a 15° contact angle.
- E: Represents an optimized internal design, including a larger ball complement and a phenolic cage for enhanced performance.
- GB: Signifies a Light preload / Class B.
- P4A: Denotes an ultra-precision tolerance class superior to ABEC 7, ensuring extremely tight dimensional control.
7006 CEGB/P4A Bearing Structural Features & Performance Benefits
- High-Speed Capability: The lightweight, durable phenolic resin cage and optimized internal geometry enable a high limiting speed of 100,500 rpm, reducing centrifugal forces and heat generation.
- Precision & Rigidity: Manufactured to P4A tolerances with a universal match (SU) design, these bearings can be paired to achieve precise axial rigidity and minimal runout, which is critical for high-precision spindles.
- Combined Load Capacity: The 15° contact angle is engineered to efficiently support significant combined radial and axial loads (Dynamic: 2106 lbf, Static: 1170 lbf).
- Optimized Internal Design: Features 17 high-grade chrome steel balls of 6.35mm diameter, providing a robust load-carrying structure and smooth operation.
