7015 CE/P4AQBCA Bearing Product Overview & Core Advantages
The 7015 CE/P4AQBCA is a precision angular contact ball bearing designed for demanding applications requiring exceptional rigidity and accuracy. As part of a Quadruplex Back-to-Back (QBC) matched set, this bearing configuration delivers superior stiffness and can accommodate combined loads (radial and axial) from both directions. Manufactured to P4A tolerance class, it ensures high running accuracy and is preloaded for immediate, precise operation. Its phenolic cage and optimized design contribute to excellent high-speed performance, making it ideal for high-precision, high-reliability machinery.

7015 CE/P4AQBCA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The Quadruplex Back-to-Back (QBC) arrangement creates an extremely rigid bearing system capable of withstanding heavy combined loads and moments. The 15° contact angle further enhances axial load capacity while maintaining excellent radial load performance.
- Precision & High-Speed Performance: Manufactured to P4A tolerance standards, this bearing ensures minimal runout and vibration. The lightweight phenolic cage is designed for high-speed applications, reducing centrifugal forces and allowing for a limiting speed of 24,000 rpm.
- Optimized for Matched Sets: As a component of a precisely matched set of four bearings, it guarantees consistent performance, simplified installation, and predictable system behavior under load.
- Superior Material Construction: Made from chrome steel for both rings and balls, the bearing offers high durability, wear resistance, and a long operational lifespan under demanding conditions.
7015 CE/P4AQBCA Bearing Typical Application Areas
