7014 CBG/P4AG0 Bearing Product Overview & Core Advantages
The 7014 CBG/P4AG0 is a single-row angular contact ball bearing designed for applications demanding high precision and superior running accuracy. Engineered to accommodate combined loads (radial and axial) simultaneously, this bearing features a 15° contact angle for optimal axial load capacity. Its P4A tolerance class ensures exceptional dimensional and rotational precision, making it ideal for high-speed spindle applications and other precision machinery where minimal runout and vibration are critical.
7014 CBG/P4AG0 Bearing Model Code Explained, Specifications & Naming Convention
The model number 7014 CBG/P4AG0 is decoded as follows:
- 7014: Basic bearing series, indicating a 70mm bore and standard cross-section.
- C: Denotes a 15° contact angle.
- B: Indicates a Universal Matchable (SU) bearing, designed to be mounted in a matched set (back-to-back, face-to-face, or tandem) with another identical bearing to achieve specific preload and rigidity characteristics.
- G: Specifies that the bearing is supplied Lubricated with grease.
- /P4A: Defines the tolerance class to ABEC 7 / ISO P4A, signifying very high precision for bore diameter, outside diameter, and width.
- G0: Specifies a specific preload level (light preload).
7014 CBG/P4AG0 Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: Manufactured to P4A tolerance class, this bearing guarantees tight dimensional control and low runout. The Universal Matchable (SU) design allows for precise preload adjustment when used in a matched set, resulting in a highly rigid bearing system that minimizes deflection under load.
- Optimized Load Capacity: The 15° contact angle is engineered to efficiently support significant axial loads in one direction, as well as combined radial and axial loads.
- High-Speed Capability: The lightweight and robust phenolic resin cage ensures stable operation and reduced centrifugal forces, contributing to a high limiting speed of 29,000 rpm. The open design facilitates efficient lubrication and heat dissipation.
- Premium Materials: Constructed from chrome steel for both rings and balls, ensuring high durability, wear resistance, and a long operational lifespan under demanding conditions.
7014 CBG/P4AG0 Bearing Typical Application Areas
This high-precision angular contact bearing is ideally suited for:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Grinding Spindles
- High-Frequency Motors
- Industrial Pumps and Compressors
- Aerospace and Defense Systems
