7013 CD/P4ADGC Bearing Product Overview & Core Advantages
The 7013 CD/P4ADGC is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. As a universal matchable (SU) bearing supplied in a pre-set pair, it enables simplified installation and optimal performance in high-speed configurations. Its 15° contact angle and moderate preload (Class C) provide superior stability and the capacity to handle combined loads, making it an ideal choice for high-reliability machinery.
7013 CD/P4ADGC Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CD | A 15° contact angle and specific internal design for optimized load distribution. |
| P4A | Indicates a high-precision tolerance class with very tight running accuracy limits. |
| DGC | Signifies the bearing is part of a universally matchable (SU) pair, allowing any two bearings to be mounted together without performance loss. |
7013 CD/P4ADGC Bearing Structural Features & Performance Benefits
- High Rigidity & Stability: The phenolic cage and universal matching design ensure stable operation under high speeds and loads. The moderate preload eliminates internal clearance, significantly enhancing system rigidity and reducing vibration.
- Superior Load Capacity: The angular contact design with a 15° contact angle efficiently supports combined radial and axial loads simultaneously. The high dynamic (15,210 lbf) and static (16,875 lbf) load ratings ensure long service life.
- Optimized High-Speed Performance: The lightweight phenolic cage and precision-ground chrome steel components contribute to a high limiting speed of 24,000 rpm, making it suitable for demanding spindle applications.
- Precision Engineering: Manufactured to P4A tolerance class with tight dimensional controls on the bore diameter (65 mm), outside diameter (100 mm), and width (36 mm) for exacting performance requirements.
