7007 ACE/P4BVG275 Bearing Product Overview & Core Advantages
The 7007 ACE/P4BVG275 is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. As a single-row bearing, it is optimized to support high combined loads (radial and axial) in one direction. Its key advantages include a P4 (ABEC-7) tolerance class for superior running accuracy, a 25° contact angle for excellent axial load capacity, and a phenolic resin cage enabling high-speed operation. This bearing is pre-lubricated and available with a preload, making it ideal for high-precision, high-reliability machinery.
