71932 CDGB/P4A Bearing Product Overview & Core Advantages
The 71932 CDGB/P4A is a single-row angular contact ball bearing designed for high-precision applications requiring exceptional rotational accuracy and rigidity. Manufactured to P4A tolerance class, this bearing delivers superior running precision and is universally matchable (SU), allowing for precise preload control when mounted in sets. Its 15° contact angle is optimized to handle significant combined loads (radial and axial) simultaneously, making it ideal for demanding machinery where space constraints and high reliability are critical.

71932 CDGB/P4A Bearing Structural Features & Performance Benefits
Precision Engineering: The P4A tolerance class ensures minimal runout and vibration, critical for high-speed applications up to 11,000 rpm. The phenolic resin cage provides excellent dimensional stability and reduced friction at high speeds.
Superior Load Capacity: With a dynamic load rating of 29,250 lbf and static load rating of 36,000 lbf, this bearing reliably handles demanding combined radial and axial loads. The optimized 15° contact angle provides balanced load distribution between radial and axial directions.
Material Excellence: Manufactured from chrome steel for both rings and balls, the bearing offers exceptional hardness, wear resistance, and fatigue life. The precision-ground 19.05 mm balls (28 in quantity) ensure smooth operation and consistent performance.
Thermal Stability: The phenolic cage material maintains dimensional stability across the operating temperature range of -30°C to 110°C, ensuring reliable performance in varying environmental conditions.
