7008 CD/P4ADGA Bearing Product Overview & Core Advantages
The 7008 CD/P4ADGA is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. Manufactured to ABEC 7/P4A tolerance class, this bearing excels in high-speed operations while maintaining dimensional stability. Its universal matchable (SU) design allows for flexible mounting configurations in preloaded pairs, enabling optimal performance under combined radial and axial loads. The phenolic cage and chrome steel construction ensure reliable operation in demanding precision equipment.
7008 CD/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Benefit |
|---|---|---|
| CD | 15° contact angle with optimized internal design | Enhanced axial load capacity and high-speed capability |
| P4A | High precision tolerance class (ABEC 7 equivalent) | Superior running accuracy and minimal vibration |
| DGA | Universal matchable bearing in preloaded pairs | Simplified mounting and consistent preload performance |
7008 CD/P4ADGA Bearing Structural Features & Performance Benefits
High Precision Construction: The P4A tolerance class ensures minimal dimensional variation, critical for applications requiring precise shaft positioning and minimal runout.
Optimized Load Distribution: With a 15° contact angle and 18 precision balls, the bearing effectively handles combined loads while maintaining high rigidity during operation.
Superior High-Speed Performance: The phenolic cage provides excellent strength-to-weight ratio, contributing to the limiting speed of 43,000 rpm while reducing centrifugal forces.
Universal Matching Capability: As universal matchable (SU) bearings, they can be mounted in various preload configurations (back-to-back, face-to-face, or tandem) without selective matching.
Premium Material Selection: Chrome steel rings and balls ensure high durability and wear resistance, while the phenolic cage offers smooth operation at high speeds.
