S7010 CD/P4AQBCC Bearing Product Overview & Core Advantages
The S7010 CD/P4AQBCC is a precision angular contact ball bearing designed for the most demanding applications. Its defining feature is its matched quadruplex back-to-back (QBC) arrangement, which delivers exceptional system rigidity and stability under complex loading conditions. This bearing is manufactured to a P4A tolerance class, ensuring ultra-high running accuracy. Pre-loaded to Moderate / Class C, it is optimized to handle significant combined radial and axial loads simultaneously, making it an ideal choice for high-speed, high-precision spindles and machinery where uncompromising performance is critical.
S7010 CD/P4AQBCC Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| S7010 | Bearing series and size designation (10mm bore x 30mm OD series) | Identifies the fundamental bearing dimensions. |
| CD | 15° contact angle | Optimized for high-speed operation and axial load capacity. |
| P4A | High precision tolerance class | Guarantees ultra-precise running accuracy and minimal vibration. |
| QBCC | Quadruplex Back-to-Back arrangement, Moderate (C) preload | Specifies the matched set of 4 bearings, providing maximum rigidity and moment load capacity. |
S7010 CD/P4AQBCC Bearing Structural Features & Performance Benefits
Unmatched Rigidity and Load Capacity: The quadruplex back-to-back arrangement creates an extremely stiff bearing system capable of withstanding heavy combined loads and significant moment loads, which is critical for maintaining precision in machine tool spindles.
High-Speed Capability: The 15° contact angle and lightweight phenolic cage are engineered for high-speed operation, reducing centrifugal forces and operating temperatures. The grease lubrication is selected for reliable performance within the specified speed and temperature range.
Precision Engineering: Manufactured to P4A tolerance class with tight bore, outside diameter, and width tolerances, this bearing ensures minimal runout and superior rotational accuracy for applications requiring the highest level of precision.
Durability and Sealed Protection: Constructed from chrome steel for both rings and balls, the bearing offers high durability and fatigue life. The sealed design protects the precision-ground components and factory-applied grease from contamination.
S7010 CD/P4AQBCC Bearing Typical Application Areas
The S7010 CD/P4AQBCC is specifically engineered for high-performance applications, including:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Rotary Tables: Indexing and positioning systems.
- High-Frequency Motors and Spindles: Where extreme rigidity and speed are required.
