7007 FE/HCP4ADBG2 Bearing Product Overview & Core Advantages
The 7007 FE/HCP4ADBG2 is a precision angular contact ball bearing designed for demanding applications requiring exceptional high rigidity and accuracy. This duplex back-to-back (DB) matched set is preloaded and ready for installation, offering superior performance in handling combined radial and axial loads. Manufactured to the stringent P4A tolerance class, it features a phenolic cage and ceramic balls, making it an ideal solution for high-speed and high-precision machinery where reliability and dimensional stability are critical.
7007 FE/HCP4ADBG2 Bearing Model Code Explained, Specifications & Naming Convention
- 7007: Basic bearing series, indicating a 35mm bore, 62mm OD, and 28mm width.
- FE: Designates a specific internal design and preload level for the matched set.
- HC: Indicates the use of Hybrid Ceramic balls (Silicon Nitride).
- P4A: Denotes a super-precision tolerance class exceeding ABEC 7/ISO P4 standards.
- DB: Specifies the Duplex Back-to-Back mounting arrangement.
- G2: Indicates the specific preload group for the matched pair.
7007 FE/HCP4ADBG2 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The duplex back-to-back (DB) arrangement creates a rigid bearing system that effectively resists moment loads and provides exceptional stability. This configuration, combined with the 18° contact angle, delivers superior performance for combined radial and axial loads.
High-Speed Performance: The combination of a lightweight phenolic resin cage and low-density ceramic (Si3N4) balls significantly reduces centrifugal forces, enabling a high limiting speed of 56,000 rpm. This makes the bearing ideal for high-speed spindles.
Precision & Longevity: Manufactured to P4A tolerance class with a narrow bore and outside diameter tolerance band, this bearing ensures minimal runout and precise rotational accuracy. The open seal type allows for optimized lubrication management in controlled environments.
Preloaded & Matched Set: Supplied as a preloaded matched set of 2 bearings, this simplifies installation, guarantees optimal preload, and ensures consistent, high-performance operation directly out of the box.
7007 FE/HCP4ADBG2 Bearing Typical Application Areas
This high-precision bearing is engineered for advanced applications where speed, accuracy, and rigidity are paramount. Key industries and equipment include:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Robotics: Arm joints and high-accuracy rotary axes.
- Aerospace & Defense Systems: Gyroscopes, radar systems, and navigation equipment.
- High-Frequency Motors and Spindles: PCB drilling spindles and dental handpieces.
