7013 CD/P4ADGB Bearing Product Overview & Core Advantages
The 7013 CD/P4ADGB is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. Manufactured to P4A tolerance class, it offers superior dimensional and running accuracy. Its universal matchable (SU) design allows for flexible mounting in various preload configurations, enabling optimal performance in high-speed and high-precision systems. The bearing is pre-lubricated and features a light preload (Class B), making it ready for immediate installation and operation in demanding environments.
7013 CD/P4ADGB Bearing Model Code Explained, Specifications & Naming Convention
The model number 7013 CD/P4ADGB provides detailed technical specifications:
- 7013: Basic bearing series and size designation (65mm bore, 100mm OD, 36mm width).
- C: Indicates a 15° contact angle, optimized for handling combined loads.
- D: Signifies the light preload (Class B) applied to the bearing set.
- P4A: Denotes the super-precision tolerance class, ensuring extremely tight dimensional and running accuracy.
- DGB: Indicates that the bearing is part of a Universal Matchable (SU) pair ("Duplex Group Back-to-Back"), supplied as a set of two bearings designed to be mounted in a back-to-back arrangement.
7013 CD/P4ADGB Bearing Structural Features & Performance Benefits
The performance of the 7013 CD/P4ADGB is derived from its meticulous design and material selection:
- High Rigidity & Load Capacity: The angular contact design with a 15° contact angle enables the bearing to support significant combined radial and axial loads simultaneously. The universal matchable duplex set further enhances system rigidity and moment load capacity.
- Super-Precision Performance: Manufactured to P4A tolerance class, this bearing guarantees minimal runout and vibration, which is critical for applications requiring high rotational accuracy.
- High-Speed Capability: The lightweight phenolic resin cage and optimized internal geometry contribute to lower friction and a high limiting speed of 24,000 rpm, making it suitable for high-speed spindles.
- Optimized for Matched Sets: Supplied as a universal matchable pair, these bearings are designed to be mounted in a back-to-back configuration, simplifying installation and ensuring pre-defined, consistent preload and performance.
7013 CD/P4ADGB Bearing Typical Application Areas
This high-precision bearing is ideally suited for advanced machinery and equipment where accuracy, speed, and rigidity are paramount. Key applications include:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Grinding Spindles
- High-Frequency Motors
- Industrial Pumps and Compressors
- Medical and Laboratory Equipment
