S7010 CD/HCP4AQBCA Bearing Product Overview & Core Advantages
The S7010 CD/HCP4AQBCA is a high-precision quadruplex back-to-back angular contact ball bearing designed for demanding applications requiring exceptional rigidity and rotational accuracy. This matched set of four bearings provides superior stiffness and load-carrying capacity in a compact assembly. Engineered with a 15° contact angle and P4A super-precision tolerance, it is optimized to handle combined radial and axial loads simultaneously. The use of ceramic balls and a phenolic cage enables outstanding high-speed performance, making it an ideal solution for ultra-precise, high-reliability machinery.
S7010 CD/HCP4AQBCA Bearing Model Code Explained, Specifications & Naming Convention
- S7010: Basic bearing series and size designation (50mm bore, 80mm OD).
- CD: Indicates a duplex pair with specific internal preload and alignment.
- HC: Denotes the use of Hybrid Ceramic components (ceramic balls).
- P4A: Specifies the tolerance class, indicating ultra-high precision and running accuracy.
- QBC: Stands for Quadruplex Back-to-Back arrangement, a matched set of four bearings configured for maximum rigidity.
S7010 CD/HCP4AQBCA Bearing Structural Features & Performance Benefits
Exceptional Rigidity and Load Capacity: The quadruplex back-to-back configuration creates an extremely rigid bearing system, capable of withstanding heavy combined loads and moments. This design is essential for applications where shaft deflection must be minimized.
Superior High-Speed Performance: The combination of lightweight phenolic resin cage and low-density silicon nitride (Si3N4) ceramic balls reduces centrifugal forces, lowers operating temperature, and allows for a limiting speed of 46,000 rpm. This makes it a premier choice for high-speed spindles.
Precision and Longevity: Manufactured to P4A tolerance class, this bearing ensures minimal runout and vibration. The sealed design and pre-applied grease lubrication protect against contamination and provide reliable operation within a temperature range of -30°C to 110°C.
S7010 CD/HCP4AQBCA Bearing Typical Application Areas
This high-performance bearing set is specifically engineered for the most critical applications, including:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Grinding Spindles: Applications requiring the utmost in rotational accuracy and finish.
- High-Frequency Motors and Spindles
- Aerospace and Defense Instrumentation
