7212 BEGAP Bearing Product Overview & Core Advantages
The 7212 BEGAP is a single row angular contact ball bearing engineered for high-precision applications requiring exceptional performance under combined loads. Featuring a 40° contact angle and manufactured to P6 (ABEC-3) tolerance class, this bearing is designed to accommodate significant axial loads in one direction while simultaneously handling radial loads. Its precision construction ensures high rigidity and operational accuracy, making it an ideal component for demanding industrial environments where reliability and precision are paramount.
7212 BEGAP Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7212 | Basic bearing designation indicating a metric series angular contact ball bearing with 60mm bore, 110mm OD, and 22mm width. |
| BE | Designates 40° contact angle and optimized internal geometry for high axial load capacity. |
| GA | Indicates light preload for enhanced rigidity and precise rotational accuracy. |
| P | Specifies P6 tolerance class (equivalent to ABEC-3) for high precision applications. |
7212 BEGAP Bearing Structural Features & Performance Benefits
This bearing's performance stems from its carefully engineered structural characteristics:
- High Rigidity & Load Capacity: The 40° contact angle and optimized raceway geometry enable superior axial load carrying capacity while maintaining excellent radial load performance. The light preload (GA) ensures minimal deflection under operational stresses.
- Precision Performance: Manufactured to P6 tolerance class with a nylon cage, the bearing delivers consistent, high-accuracy rotation suitable for precision machinery.
- High-Speed Capability: The lightweight nylon cage reduces centrifugal forces, while the open design facilitates efficient lubrication, supporting a limiting speed of 7,500 rpm.
- Material Excellence: Constructed from chrome steel for both rings and balls, ensuring high durability, wear resistance, and consistent performance across the operating temperature range of -30°C to 110°C.
