S7007 CB/HCP4ADGA Bearing Product Overview & Core Advantages
The S7007 CB/HCP4ADGA is a precision double-row angular contact ball bearing engineered for applications demanding exceptional accuracy and reliability. Its design excels at simultaneously handling combined radial and bidirectional axial loads. Featuring a universal matchable (SU) configuration, two bearings can be paired to achieve optimal preload and rigidity. Manufactured to the stringent P4A tolerance class, it incorporates ceramic balls and a phenolic cage, making it an ideal solution for high-speed operation and high-rigidity support systems.
S7007 CB/HCP4ADGA Bearing Model Code Explained, Specifications & Naming Convention
The model number S7007 CB/HCP4ADGA is decoded as follows:
- S: Denotes a bearing with a 15° contact angle.
- 7007: Standard bore (35 mm) and outside diameter (62 mm) designation.
- CB: Indicates a Universal Matchable (SU) bearing. Two CB-designated bearings can be mounted in a universal arrangement (face-to-face or back-to-back) to share loads effectively.
- HC: Signifies the use of Hybrid Ceramic components (ceramic balls with steel rings).
- P4A: Specifies the ultra-precision tolerance class, exceeding ABEC-7 standards for running accuracy.
- DGA: Indicates the bearing is sealed and pre-lubricated with a specific grease suitable for the specified temperature range.
S7007 CB/HCP4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double-row angular contact design provides superior rigidity and enables the bearing to support significant combined loads (radial and axial from both directions). The universal matchable (SU) feature allows for precise preload setting when pairs are used.
- Superior High-Speed Performance: The combination of a lightweight phenolic cage and low-friction ceramic (hybrid) balls significantly reduces centrifugal forces and operating temperatures, enabling a high limiting speed of 41,000 rpm.
- Extended Service Life & Reliability: Hybrid ceramic construction offers enhanced durability, electrical resistance, and the ability to operate with minimal lubrication. The sealed design with pre-applied grease ensures long-term, maintenance-free operation within a temperature range of -30°C to 110°C.
- Ultra-Precision: Manufactured to P4A tolerance class, this bearing guarantees minimal runout and vibration, which is critical for maintaining high positional accuracy in sensitive equipment.
S7007 CB/HCP4ADGA Bearing Typical Application Areas
