7002 CE/P4ADT Bearing Product Overview & Core Advantages
The 7002 CE/P4ADT is a precision angular contact ball bearing designed for demanding applications requiring exceptional accuracy and performance. This duplex tandem (DT) arrangement bearing set is preloaded and manufactured to P4A tolerance class, ensuring superior running accuracy and system rigidity. Its primary advantage lies in its ability to handle high combined loads (radial and axial) in one direction with maximum stiffness, making it ideal for high-speed, high-precision spindles and positioning systems. The phenolic cage and optimized internal geometry contribute to its excellent high-speed performance and smooth operation.
