S7003 CD/P4ADGB Bearing Product Overview & Core Advantages
The S7003 CD/P4ADGB is a precision double row angular contact ball bearing designed for applications requiring exceptional accuracy and reliability. Engineered to accommodate combined loads, this bearing simultaneously handles substantial radial loads and bidirectional axial loads. Its compact design, featuring a P4A tolerance class and light preload (Class B), ensures superior running accuracy and high system rigidity, making it ideal for high-speed, high-precision machinery where minimal deflection is critical.
S7003 CD/P4ADGB Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7003 | Basic bearing series, double row angular contact design |
| CD | Specific internal design and contact angle optimization |
| P4A | High precision tolerance class exceeding ABEC 7 standards |
| DGB | Universal Matchable (SU) arrangement designation |
S7003 CD/P4ADGB Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row angular contact configuration provides significantly increased rigidity compared to single row designs, enabling stable operation under combined radial and axial loads. With a 15° contact angle and optimized internal geometry, it delivers reliable performance in demanding applications.
Precision Performance: Manufactured to P4A tolerance class with exceptionally tight dimensional tolerances (bore: -0.004mm to 0, OD: -0.004mm to 0), this bearing ensures minimal runout and vibration for high-precision applications.
High-Speed Capability: The phenolic cage provides excellent strength-to-weight ratio, contributing to the bearing's high-speed performance with a limiting speed of 85,000 rpm. The light preload (Class B) further enhances high-speed stability.
Universal Matching Design: As a Universal Matchable (SU) bearing, it can be paired with another identical bearing in various configurations to accommodate complex loading conditions without additional spacers or adjustments.
