7215 BECBJ Bearing Product Overview & Core Advantages
The 7215 BECBJ 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 a P6 (ABEC-3) tolerance class, making it ideal for arrangements demanding high running accuracy and rigidity. Its optimized internal geometry enables it to efficiently support combined radial and axial loads in one direction, making it a compact and reliable solution for high-speed machinery and precision equipment.
7215 BECBJ Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Implication |
|---|---|---|
| BE | Increased internal clearance and optimized internal design | Enhanced performance under high-speed and thermal expansion conditions |
| CB | Specific internal clearance and contact angle combination | Provides stable operation under combined loads and moderate preload conditions |
| J | Stainless steel cage construction | Improved corrosion resistance and durability at high speeds |
7215 BECBJ Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The single row design with 40° contact angle provides excellent rigidity and can support substantial combined radial and axial loads. With a dynamic load rating of 16,538 lbf and static load rating of 14,738 lbf, this bearing delivers reliable performance in demanding applications.
High-Speed Performance: The stainless steel cage and optimized internal geometry enable a limiting speed of 6,300 rpm, making it suitable for high-speed spindle applications. The precise bearing dimensions (75mm bore × 130mm OD × 25mm width) ensure stable operation at elevated speeds.
Precision Engineering: Manufactured to P6 (ABEC-3) tolerance class with tight dimensional tolerances (bore: -0.012mm to 0, OD: -0.015mm to 0), this bearing guarantees high running accuracy and consistent performance in precision machinery.
Material Excellence: Constructed from chrome steel for both rings and balls, with stainless steel cage, ensuring durability and long service life. The bearing comes pre-lubricated and operates effectively within a temperature range of -30° to 110°C.
