7206 ACDGA/P4A Bearing Product Overview & Core Advantages
The 7206 ACDGA/P4A is a single-row angular contact ball bearing designed for high-precision applications requiring exceptional rotational accuracy and rigidity. Manufactured to ABEC 7/P4A tolerance class, this bearing delivers superior dimensional stability and minimal runout. Its 25° contact angle provides optimal performance for combined loads, effectively handling both radial forces and substantial axial loads in one direction. The phenolic cage enables smooth operation at high rotational speeds up to 100,500 rpm, making it ideal for precision spindles and high-speed machinery where reliability and accuracy are critical.

7206 ACDGA/P4A Bearing Structural Features & Performance Benefits
High-Precision Construction: The 7206 ACDGA/P4A features chrome steel rings and balls with P4A tolerance classification, ensuring exceptional dimensional stability and minimal vibration. The phenolic resin cage provides excellent dimensional stability at high speeds while reducing friction and heat generation.
Optimized Load Capacity: With a 25° contact angle and precision-ground raceways, this bearing delivers superior performance under combined radial and axial loads. The dynamic load rating of 5,265 lbf and static load rating of 3,442 lbf ensure reliable operation in demanding applications.
High-Speed Capability: The lightweight phenolic cage and optimized internal geometry enable limiting speeds of 100,500 rpm, making this bearing suitable for high-speed spindle applications. The open design allows for efficient lubrication management in high-speed environments.
Universal Matching Design: As a universal matchable bearing, the 7206 ACDGA/P4A can be precisely paired with other bearings to create optimized bearing sets, typically in sets of three, for complex mounting arrangements requiring exact preload and alignment.
