7216 BEGAPH Bearing Product Overview & Core Advantages
The 7216 BEGAPH is a single row angular contact ball bearing engineered for high-precision applications requiring superior performance under combined loads. This metric bearing features a 40° contact angle and P6 (ABEC-3) precision class, making it ideally suited for machine tool spindles and other high-speed machinery where rigidity and accuracy are critical. Its optimized internal geometry enables it to handle significant radial and axial loads simultaneously, while the open design facilitates efficient lubrication management in demanding operational environments.
7216 BEGAPH Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7216 | Standard bearing size designation (80mm bore, 140mm OD, 26mm width) |
| BE | 40° contact angle design optimized for high axial load capacity |
| P | P6 precision tolerance class (equivalent to ABEC-3) |
| A | Internal design optimized for high-speed operation |
| H | Pre-lubricated with high-performance grease |
7216 BEGAPH Bearing Structural Features & Performance Benefits
Optimized Internal Geometry: The 40° contact angle and precisely calculated raceway curvature provide exceptional axial load capacity while maintaining excellent radial load performance. The distance from side face to load point (59mm) ensures optimal load distribution.
High-Speed Capability: The nylon cage minimizes friction and weight, contributing to the bearing's limiting speed of 5,600 rpm. The open design allows for efficient lubrication flow and heat dissipation during high-speed operation.
Precision Performance: Manufactured to P6 tolerance class with tight dimensional controls on bore diameter (-0.012mm to 0), outside diameter (-0.015mm to 0), and width (-0.05mm to 0), ensuring consistent performance in precision applications.
Material Excellence: Constructed from chrome steel for both rings and balls, providing high hardness, wear resistance, and durability under demanding operating conditions.
