S7016 ACEGA/HCP4A Bearing Product Overview & Core Advantages
The S7016 ACEGA/HCP4A is a high-precision angular contact ball bearing engineered for demanding applications requiring exceptional accuracy and reliability. This single bearing features an extra light preload (Class A) and is manufactured to P4A tolerance class, ensuring ultra-precise rotational performance. Its design is optimized to handle combined radial and axial loads simultaneously, making it an ideal solution for high-rigidity, high-speed systems. The combination of a phenolic cage and ceramic balls significantly enhances its high-speed capabilities and operational longevity.

S7016 ACEGA/HCP4A Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The angular contact design with a 25° contact angle provides excellent resistance to combined loads, offering high rigidity for precise shaft positioning.
Superior High-Speed Performance: The phenolic resin cage and lightweight ceramic balls (Si3N4) reduce centrifugal forces, enabling a high limiting speed of 28,000 rpm and lower operating temperatures.
Enhanced Durability & Longevity: The hybrid ceramic construction provides superior wear resistance, electrical insulation, and extended service life, especially in contaminated or high-temperature environments.
Precision Engineering: Manufactured to P4A tolerance class with tight dimensional control on bore, outside diameter, and width, ensuring minimal runout and vibration for ultra-precise applications.
Universal Matchability (SU): Can be universally matched with another identical bearing in a back-to-back (DB) or face-to-face (DF) arrangement to handle higher moment loads.
