71926 CDGB/P4A Bearing Product Overview & Core Advantages
The 71926 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 accuracy and dimensional stability. Its 15° contact angle and light preload (Class B) configuration make it ideal for applications demanding high-speed operation and precise axial positioning. The bearing comes universally matchable (SU), allowing for precise axial clearance control when mounted in sets, and features a phenolic cage optimized for high-speed performance.

71926 CDGB/P4A Bearing Structural Features & Performance Benefits
High Precision Construction: Manufactured to P4A tolerance standards with tight dimensional control (bore: -0.004mm to 0, OD: -0.004mm to 0) ensuring exceptional running accuracy and minimal vibration.
Optimized Load Capacity: The 15° contact angle provides excellent combination load handling with radial dynamic load rating of 20,768 lbf and static load rating of 24,300 lbf, suitable for applications with significant axial and radial forces.
High-Speed Capability: The phenolic cage material and optimized internal geometry enable limiting speeds up to 7,500 rpm, making it ideal for high-speed spindle applications.
Precision Matching: As a universally matchable (SU) bearing, it can be supplied in sets of 3 with precisely controlled preload, eliminating the need for manual adjustment and ensuring consistent performance.
Material Excellence: Constructed from chrome steel for both rings and balls (15.875 mm diameter, 27 balls) providing excellent wear resistance and durability under demanding operating conditions.
