S7016 ACE/HCP4ADGA Bearing Product Overview & Core Advantages
The S7016 ACE/HCP4ADGA is a precision angular contact ball bearing engineered for demanding applications requiring exceptional accuracy and performance. This universal matchable (SU) bearing features a P4A super-precision tolerance class and is designed to handle combined radial and axial loads simultaneously. Its construction with ceramic balls and a phenolic cage enables superior high-speed capabilities and thermal stability, making it ideal for high-reliability, high-rigidity applications where precision is paramount.
S7016 ACE/HCP4ADGA Bearing Model Code Explained, Specifications & Naming Convention
- S70: High-precision angular contact bearing series
- 16: Bore diameter code (80 mm)
- ACE: Specific internal design and contact angle (25°)
- HC: Hybrid Ceramic (steel rings with ceramic balls)
- P4A: Super precision tolerance class (exceeds ABEC 7)
- DGA: Preload designation (Extra light / Class A)
S7016 ACE/HCP4ADGA Bearing Structural Features & Performance Benefits
Hybrid Ceramic Construction: The combination of chrome steel rings and silicon nitride ceramic balls provides exceptional high-speed performance, reduced friction, and extended service life. The ceramic balls are electrically insulating and provide superior operation in high-temperature environments.
Precision Engineering: Manufactured to P4A tolerance class with bore and outside diameter tolerances of -0.004mm to 0, ensuring exceptional running accuracy and minimal vibration for precision applications.
Optimized Load Capacity: With a radial dynamic load rating of 11,858 lbf and radial static load rating of 11,925 lbf, this bearing delivers reliable performance under combined loading conditions. The 25° contact angle provides optimal axial load capacity while maintaining radial load capability.
High-Speed Capability: The phenolic resin cage and ceramic balls enable a limiting speed of 28,000 rpm, making it suitable for ultra-high-speed applications. The lightweight cage reduces centrifugal forces and maintains stability at extreme rotational speeds.
