S7010 CD/P4A Bearing Product Overview & Core Advantages
The S7010 CD/P4A is a precision single-row angular contact ball bearing designed for applications demanding exceptional rotational accuracy and high-speed capability. Engineered with a 15° contact angle and P4 (ABEC-7) tolerance class, it excels at supporting combined radial and axial loads. Its phenolic cage and preloaded design contribute to high rigidity and smooth operation, making it an ideal choice for high-performance spindles and precision machinery where reliability is paramount.
S7010 CD/P4A Bearing Model Code Explained, Specifications & Naming Convention
The model designation S7010 CD/P4A provides specific technical details:
- S7010: Basic model number indicating a 50mm bore, 80mm OD, 16mm width angular contact bearing.
- C: Denotes a 15° contact angle.
- D: Indicates the bearing is supplied with a preload for enhanced rigidity.
- P4A: Specifies the tolerance class P4 (ABEC-7), signifying very high precision levels for inner and outer ring runouts and dimensions.
S7010 CD/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The combination of a phenolic resin cage and a defined preload ensures minimal deflection under load, providing exceptional system stiffness and positional accuracy required for precision applications.
- Optimized Load Capacity: The 15° contact angle is engineered to efficiently handle combined radial and axial loads simultaneously, making it suitable for complex loading conditions.
- Superior High-Speed Performance: The lightweight phenolic cage reduces centrifugal forces, while the optimized internal geometry supports a high limiting speed of 17,000 rpm, enabling smooth operation at elevated rotational velocities.
- Sealed and Lubricated for Longevity: As a sealed and pre-lubricated unit, the bearing is protected from contamination and is ready for immediate installation, offering long-term, maintenance-free operation within its specified temperature range.
