7016 ACDGA/HCP4A Bearing Product Overview & Core Advantages
The 7016 ACDGA/P4A is a single-row angular contact ball bearing engineered for high-precision and high-speed applications. Its defining characteristic is the 25° contact angle and Universal Matchable (SU) design, allowing bearings to be mounted in tandem, face-to-face, or back-to-back arrangements to achieve optimal system rigidity and precise axial displacement control. Manufactured to the stringent P4A tolerance class, it delivers exceptional running accuracy. The use of a phenolic cage and ceramic balls significantly reduces weight and inertial forces, enabling superior high-speed performance and extended service life under demanding conditions.

7016 ACDGA/HCP4A Bearing Structural Features & Performance Benefits
- High-Speed Capability: The combination of a lightweight phenolic cage and low-density ceramic balls minimizes centrifugal forces, allowing for a high limiting speed of 28,000 rpm. This design reduces friction and heat generation.
- Precision & Rigidity: Manufactured to P4A super-precision standards, this bearing ensures minimal runout and vibration. The 25° contact angle provides excellent resistance to combined (radial and axial) loads.
- Universal Matching: The Universal Matchable (SU) feature allows for the creation of bearing sets with predefined preload and stiffness, simplifying installation and ensuring optimal performance in complex spindle arrangements.
- Superior Material: Ceramic balls offer advantages including higher stiffness, lower thermal expansion, and electrical insulation, making them ideal for challenging environments.
