71936 CD/P4ADGA Bearing Product Overview & Core Advantages
The 71936 CD/P4ADGA is a precision angular contact ball bearing manufactured to P4A tolerance class for exceptional dimensional accuracy and running precision. Designed with extra light preload (Class A) and a 15° contact angle, this bearing delivers superior performance in applications requiring high rotational accuracy and minimal deflection. Its universal matchable (SU) design allows for flexible mounting arrangements in pairs, enabling optimal handling of combined radial and axial loads. The phenolic cage construction and chrome steel components make it ideal for high-speed operation up to 11,000 rpm while maintaining dimensional stability across a wide temperature range (-30°C to 110°C).

71936 CD/P4ADGA Bearing Structural Features & Performance Benefits
High Precision Construction: Manufactured to P4A tolerance standards with bore and outside diameter tolerances of -0.004mm to 0, ensuring exceptional dimensional accuracy and consistent performance in precision applications.
Optimized Load Capacity: With a radial dynamic load rating of 62,100 lbf and radial static load rating of 95,625 lbf, this bearing provides reliable performance under significant combined loads. The 15° contact angle enables efficient handling of both radial and axial loads simultaneously.
High-Speed Capability: The phenolic cage material and optimized internal geometry contribute to a limiting speed of 11,000 rpm, making it suitable for high-speed spindle applications. The lightweight cage reduces centrifugal forces and maintains stability at elevated rotational speeds.
Thermal Stability: Chrome steel construction and phenolic cage provide consistent performance across a wide temperature range from -30°C to 110°C, maintaining dimensional stability and preload characteristics under varying thermal conditions.
