7016 CBGA/P4A Bearing Product Overview & Core Advantages
The 7016 CBGA/P4A is a high-precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. As a single bearing with Extra light preload (Class A), it provides precise axial positioning and minimizes deflection under light loads. Manufactured to P4A tolerance class, this bearing ensures superior running accuracy. Its universal matchable (SU) design allows for flexible mounting in various configurations, including back-to-back or face-to-face arrangements, to optimize performance for specific load conditions. The combination of a phenolic cage and a 15° contact angle enables high-speed operation up to 28,000 rpm, making it an ideal solution for high-precision, high-speed spindles.

7016 CBGA/P4A Bearing Structural Features & Performance Benefits
Precision Engineering: Manufactured to P4A tolerance class with tight dimensional tolerances (bore/OD: -0.004mm to 0), ensuring minimal runout and vibration for superior rotational accuracy.
High-Speed Capability: The phenolic resin cage provides excellent strength-to-weight ratio and operates effectively at high speeds up to 28,000 rpm, while the optimized 15° contact angle reduces heat generation.
Enhanced Rigidity: The extra light preload (Class A) eliminates internal clearance, providing increased system stiffness and precise shaft positioning without excessive friction.
Superior Load Capacity: With a dynamic load rating of 5,962 lbf and static load rating of 5,130 lbf, this bearing handles combined radial and axial loads effectively.
Universal Matching: The SU universal matching designation allows for flexible arrangement in pairs, enabling optimal performance for specific application requirements.
