7030 CD/P4ATGB Bearing Product Overview & Core Advantages
The 7030 CD/P4ATGB is a precision angular contact ball bearing designed for demanding applications requiring exceptional rotational accuracy and rigidity. As a universal matchable (SU) bearing supplied in sets of three, it enables flexible mounting configurations to optimize system performance. Its P4A tolerance class ensures ultra-precise dimensions and running accuracy, while the light preload (Class B) minimizes deflection under operational stresses. This bearing excels in handling combined loads with its 15° contact angle, making it ideal for high-speed, high-rigidity applications where precision is paramount.
7030 CD/P4ATGB Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7030 | Basic bearing designation indicating bore diameter (150 mm) and series |
| CD | Contact angle of 15° and universal matchable design |
| P4A | High precision tolerance class with enhanced running accuracy |
| TGB | Phenolic (textile glass reinforced) cage material |
7030 CD/P4ATGB Bearing Structural Features & Performance Benefits
High Rigidity & Precision: The angular contact design with 15° contact angle provides exceptional stiffness against combined radial and axial loads. Manufactured to P4A tolerance standards, this bearing ensures minimal runout and vibration for precision applications.
Optimized Cage Design: The phenolic cage (TGB) offers excellent strength-to-weight ratio, reducing centrifugal forces and enabling higher limiting speeds up to 11,000 rpm. This material provides superior performance in high-speed applications compared to metallic cages.
Universal Matching Capability: As a universal matchable (SU) bearing supplied in sets of three, these bearings can be arranged in various configurations (back-to-back, face-to-face, or tandem) to meet specific application requirements for preload and stiffness.
Premium Material Construction: Manufactured from chrome steel for both rings and balls, this bearing delivers consistent performance, high load capacity, and extended service life under demanding operating conditions.
