7015 CB/P4A Bearing Product Overview & Core Advantages
The 7015 CB/P4A is a single-row angular contact ball bearing designed for high-precision applications requiring exceptional rotational accuracy and rigidity. Engineered to a P4 (ABEC-7) tolerance class, it is optimized to handle significant combined loads, accommodating both radial and axial loads in one direction. Its 15° contact angle provides a balanced performance for high-speed operation and high system rigidity. Preloaded and pre-lubricated, this bearing is ready for installation, offering reliable performance in demanding environments.
7015 CB/P4A Bearing Model Code Explained, Specifications & Naming Convention
The model number 7015 CB/P4A breaks down as follows:
- 7015: Basic series number, indicating a metric bearing with a 75mm bore and 115mm outside diameter.
- C: Denotes a 15° nominal contact angle.
- B: Indicates a moderate preload applied to the bearing.
- P4A: Specifies the tolerance class P4 (ABEC-7) with specific dimensional and running accuracy requirements.
7015 CB/P4A Bearing Structural Features & Performance Benefits
The 7015 CB/P4A's design delivers distinct performance advantages:
- High Rigidity & Precision: The single-row angular contact design, combined with a P4 tolerance class and preload, ensures minimal deflection under load, providing superior shaft positioning accuracy and system stiffness.
- Optimized Load Capacity: Engineered to support combined radial and axial loads simultaneously. With a dynamic load rating of 4478 lbf and a static load rating of 3960 lbf, it is built for demanding applications.
- High-Speed Capability: The lightweight phenolic resin cage and optimized internal geometry contribute to a high limiting speed of 24,000 rpm, reducing centrifugal forces and friction.
- Ready-to-Use Performance: The bearing comes pre-lubricated and is designed for a standard operating temperature range of -30°C to 110°C, ensuring immediate and reliable operation upon installation.
