7000 CD/P4ADGC Bearing Product Overview & Core Advantages
The 7000 CD/P4ADGC is a precision angular contact ball bearing manufactured to P4A tolerance class for exceptional dimensional and running accuracy. Engineered with a 15° contact angle and Moderate (Class C) preload, this bearing is optimized to handle combined loads—significant radial loads alongside axial loads in one direction. Its Universal Matchable (SU) design allows for flexible pairing in duplex sets to achieve various preload and stiffness requirements, making it an ideal solution for high-precision and high-rigidity applications where rotational accuracy is paramount.
7000 CD/P4ADGC Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CD | Indicates a 15° contact angle and a specific internal design optimized for high-precision applications. |
| P4A | Denotes an ABEC 7 / ISO P4 precision class with additional running accuracy requirements for superior performance. |
| DGC | Signifies a Universal Matchable (SU) bearing, designed to be paired in any combination (DB, DF, DT) without shimming. |
7000 CD/P4ADGC Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The angular contact design and Moderate preload provide exceptional system stiffness and minimize axial and radial runout, which is critical for maintaining accuracy under load.
- Superior Load Capacity: Engineered to support combined radial and axial loads efficiently. The dynamic load rating of 1492 lbf and static load rating of 731 lbf ensure reliable performance in demanding conditions.
- Optimized High-Speed Performance: The lightweight phenolic resin cage reduces centrifugal forces, contributing to a high limiting speed of 185,000 rpm. The open design and factory-applied lubrication facilitate efficient heat dissipation.
- Premium Material Construction: Manufactured from chrome steel for both rings and balls, ensuring high durability, wear resistance, and long service life.
7000 CD/P4ADGC Bearing Typical Application Areas
This precision angular contact ball bearing is ideally suited for high-performance machinery requiring exceptional accuracy and rigidity, including:
- Machine Tool Spindles
- High-Frequency Spindles
- Precision Grinding Equipment
- Medical and Dental Handpieces
- Aerospace Instrumentation
