S71916 CD/HCP4ADGA Bearing Product Overview & Core Advantages
The S71916 CD/HCP4ADGA is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional accuracy and performance. This sealed double row angular contact ball bearing features a universal match (SU) design, allowing two bearings to be paired for optimal performance. Its core advantages include the ability to simultaneously handle combined loads (radial and bidirectional axial loads), superior running accuracy from its P4A tolerance class, and high-speed capability enabled by its phenolic cage and ceramic balls. This combination makes it ideal for high-rigidity, high-reliability installations.
S71916 CD/HCP4ADGA Bearing Model Code Explained, Specifications & Naming Convention
- S7: High precision bearing series
- 1916: Standard size designation (Bore: 80mm, OD: 110mm, Width: 32mm)
- CD: Double row angular contact ball bearing with a 15° contact angle
- HC: Hybrid Ceramic (Ceramic balls with steel rings)
- P4A: High precision tolerance class, exceeding ABEC 7/ISO P4
- DGA: Sealed on both sides, pre-lubricated with grease
S71916 CD/HCP4ADGA Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides significantly increased rigidity and enables the bearing to support substantial combined loads and bidirectional axial loads, making it suitable for complex loading conditions.
High-Speed Performance: The combination of a lightweight phenolic cage and low-friction ceramic balls (Hybrid) drastically reduces centrifugal forces and heat generation, allowing for a high limiting speed of 28,000 rpm. This makes it an excellent high-speed bearing.
Precision & Longevity: Manufactured to a P4A tolerance class, it ensures minimal runout and vibration. The integral seals (DGA) retain lubrication and effectively exclude contaminants, resulting in a long, maintenance-free service life within the specified temperature range.
