7007 CE/P4BVG275 Bearing Product Overview & Core Advantages
The 7007 CE/P4BVG275 is a high-precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. Engineered to a P4 (ABEC-7) tolerance class, this bearing excels in high-speed spindles and precision machinery. Its key advantage lies in its ability to support combined loads, effectively carrying significant radial loads alongside thrust loads in one direction. The optimized 15° contact angle provides an excellent balance between radial load capacity and axial stiffness, making it an ideal component for systems requiring high positional accuracy and dynamic performance.

7007 CE/P4BVG275 Bearing Structural Features & Performance Benefits
High Rigidity & Precision: The angular contact design and P4 precision ensure minimal runout and superior dimensional stability under load. The phenolic resin cage provides excellent dimensional stability and reduced friction at high speeds.
Superior Load Capacity: With a dynamic load rating of 2565 lbf and static load rating of 1474 lbf, this bearing handles significant combined loads efficiently. The 15° contact angle is optimized for applications requiring both radial support and unidirectional thrust capacity.
High-Speed Performance: Featuring a lightweight phenolic cage and precision-ground chrome steel components, the bearing achieves a limiting speed of 34,000 rpm. The open design allows for efficient lubrication management in high-speed applications.
Pre-Configured Performance: The BVG275 suffix indicates the bearing is supplied with a specific preload, ensuring predictable performance and eliminating the need for complex adjustment during installation.
