S7016 CDGB/P4A Bearing Product Overview & Core Advantages
The S7016 CDGB/P4A is a high-precision angular contact ball bearing engineered for applications demanding exceptional rotational accuracy and rigidity. As a single bearing with a Universal Matchable (SU) designation, it can be paired with other identical bearings in specific arrangements to achieve optimal preload and performance. Its 15° contact angle and P4A tolerance class make it ideally suited for handling combined loads (radial and axial) simultaneously, providing reliable operation in high-speed, high-rigidity scenarios such as precision spindles.
S7016 CDGB/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7016 | Basic bearing series and size designation (80mm bore, 125mm OD). |
| C | 15° nominal contact angle. |
| DGB | Light preload (Class B). |
| P4A | High precision tolerance class, exceeding ABEC-7 standards for running accuracy. |
S7016 CDGB/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The optimized internal geometry and 15° contact angle provide superior stiffness, enabling the bearing to support significant radial dynamic load ratings of 14,625 lbf and axial loads effectively.
- High-Speed Performance: The phenolic cage ensures low friction and high strength, contributing to a high limiting speed of 28,000 rpm. This makes it an excellent high-speed bearing.
- Precision & Accuracy: Manufactured to P4A tolerance class with tight dimensional controls on bore, outside diameter, and width, guaranteeing exceptional running accuracy for precision applications.
- Sealed & Lubricated for Life: The sealed design with grease lubrication protects against contamination and provides long-term, maintenance-free operation within a temperature range of -30°C to 110°C.
S7016 CDGB/P4A Bearing Typical Application Areas
This bearing is ideally suited for high-performance machinery requiring precision and speed, including:
- Machine Tool Spindles
- High-Frequency Motors
- Precision Grinding Equipment
- Industrial Pumps and Compressors
