S7010 CD/P4ADBB Bearing Product Overview & Core Advantages
The S7010 CD/P4ADBB is a precision duplex angular contact ball bearing configured in a back-to-back (DB) arrangement. Engineered for applications demanding exceptional rotational accuracy and rigidity, this matched set is preloaded to Light / Class B specifications, ensuring minimal axial and radial play for superior system stability. Its primary advantage lies in its ability to handle combined loads—significant radial loads alongside bidirectional axial loads—making it an ideal solution for high-precision, high-rigidity spindles and machinery. Manufactured to a P4A tolerance class, it guarantees outstanding running accuracy and consistent performance.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| S7010 | Basic bearing designation, indicating a 50 mm bore, 80 mm OD, and 32 mm width. |
| C | 15° contact angle, optimized for carrying combined loads. |
| D | Duplex bearing set. |
| P4A | High precision tolerance class, exceeding ABEC 7/ISO P4 standards for superior running accuracy. |
| DB | Back-to-Back arrangement, providing high moment rigidity and excellent stability under complex loads. |
| B | Light preload grade, reducing deflection and vibration for smooth, precise operation. |
S7010 CD/P4ADBB Bearing Structural Features & Performance Benefits
- High Rigidity & Stability: The duplex back-to-back (DB) arrangement creates a robust, statically determinate system that offers exceptional resistance to moment loads and shaft misalignment, ensuring maximum system rigidity.
- Superior Load Capacity: With a 15° contact angle and a dynamic load rating of 10,980 lbf, this bearing set is engineered to handle significant combined radial and axial loads from both directions simultaneously.
- Precision & High-Speed Performance: The P4A tolerance class ensures minimal runout and vibration. The phenolic cage offers low weight and excellent high-speed characteristics, contributing to a high limiting speed of 46,000 rpm.
- Sealed & Pre-Lubricated: As a sealed bearing pre-lubricated with grease, it is protected from contamination and is ready for immediate installation, offering a long service life within its specified temperature range of -30°C to 110°C.
