7007 CD/P4ATBTC Bearing Product Overview & Core Advantages
The 7007 CD/P4ATBTC is a precision angular contact ball bearing designed for demanding applications requiring high rigidity and exceptional running accuracy. This bearing is supplied as a triplex back-to-back (TBT) matched set, preloaded to Moderate / Class C specifications, ensuring optimal stiffness and minimal axial and radial runout. Its configuration is engineered to handle combined loads efficiently, making it an ideal solution for high-precision spindles and other machinery where positional accuracy and high rigidity are paramount.
7007 CD/P4ATBTC Bearing Model Code Explained, Specifications & Naming Convention
The model number 7007 CD/P4ATBTC is decoded as follows:
- 7007: Basic series designation, indicating a 35mm bore, 62mm OD, and 14mm width per single bearing.
- C: Denotes a 15° contact angle, optimized for high-speed operation and moderate axial load capacity.
- D: Indicates a specific internal design and tolerance level.
- P4A: The tolerance class, signifying very high precision levels with tight dimensional and running accuracy tolerances.
- TBT: Specifies the bearing arrangement as a Triplex Back-to-Back matched set of three bearings.
- C: Indicates the preload level is Moderate (Class C).
7007 CD/P4ATBTC Bearing Structural Features & Performance Benefits
- High Rigidity & Stability: The triplex back-to-back (TBT) arrangement creates a highly rigid bearing system that effectively resists moment loads and maintains shaft positioning under combined loads.
- Precision Performance: Manufactured to P4A tolerance class, this bearing guarantees extremely low runout and smooth, quiet operation, which is critical for high-speed and high-precision applications.
- Optimized Load Capacity: The 15° contact angle provides an excellent balance, enabling the bearing to handle significant radial loads alongside moderate axial loads from both directions.
- High-Speed Capability: The lightweight phenolic cage minimizes centrifugal forces, reduces friction, and contributes to a high limiting speed of 56,000 rpm, making it suitable for high-speed spindles.
- Superior Material: Constructed from chrome steel for both rings and balls, ensuring high durability, wear resistance, and a long operational lifespan.
7007 CD/P4ATBTC Bearing Typical Application Areas
This precision bearing set is ideally suited for applications where maximum rigidity and accuracy are non-negotiable. Key industries and equipment include:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Grinding Spindles
- High-Frequency Motors
- Medical and Dental Equipment Spindles
- Advanced Robotics and precision rotary axes.
