S7202 ACDGB/P4A Bearing Product Overview & Core Advantages
The S7202 ACDGB/P4A is a precision angular contact ball bearing engineered for high-performance applications requiring exceptional accuracy and reliability. This single-row bearing features a 25° contact angle and is supplied as a universally matchable (SU) set, allowing for precise preload configuration when mounted in pairs. Its P4A tolerance class ensures superior dimensional and running accuracy, making it ideal for applications demanding high rigidity and smooth operation under combined radial and axial loads. The phenolic cage and optimized internal geometry contribute to its excellent high-speed capabilities, with a limiting speed of 115,000 rpm.

S7202 ACDGB/P4A Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The 25° contact angle and robust internal construction enable the bearing to efficiently support significant combined radial and axial loads. The universal matching (SU) feature allows for precise axial preload when mounted in pairs (back-to-back or face-to-face), significantly increasing system rigidity.
High-Speed Performance: The lightweight phenolic resin cage minimizes centrifugal forces, reduces friction, and ensures stable operation at the high limiting speed of 115,000 rpm. The optimized internal geometry further enhances high-speed capability.
Precision & Longevity: Manufactured to a P4A tolerance class, this bearing guarantees minimal runout and vibration. The chrome steel rings and balls, combined with factory-applied grease lubrication, provide long service life and reliable performance within a temperature range of -30°C to 110°C.
