7320 BECBY Bearing Product Overview & Core Advantages
The 7320 BECBY is a single row angular contact ball bearing designed for high-precision applications requiring exceptional performance under combined loads. This precision bearing features a 40° contact angle, enabling it to support significant radial loads and unidirectional axial loads simultaneously. Manufactured to P6 (ABEC-3) tolerance class, it delivers superior running accuracy and rotational stability. Its optimized internal geometry and brass cage contribute to reliable operation in demanding conditions, making it an ideal solution for applications where high rigidity and precise shaft positioning are critical.
7320 BECBY Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7320 | Basic bearing designation indicating bearing dimensions: 100mm bore, 215mm OD, 47mm width |
| BE | 40° contact angle design, optimized for high axial load capacity |
| CB | Enhanced internal design with modified raceway geometry and larger ball complement |
| Y | Brass cage (machined window type) for superior guidance and high-speed performance |
7320 BECBY Bearing Structural Features & Performance Benefits
Optimized Load Distribution: The 40° contact angle and enhanced internal design (CB suffix) provide excellent capacity for combined loads, with a radial dynamic load rating of 48,600 lbf and radial static load rating of 46,800 lbf.
High-Speed Capability: The precision-machined brass cage (Y suffix) ensures stable operation at limiting speeds up to 4,000 rpm, reducing friction and maintaining alignment under high rotational forces.
Precision Engineering: Manufactured to P6 tolerance class with tight dimensional controls (bore tolerance: -0.015mm to 0), this bearing delivers exceptional running accuracy and minimal vibration for precision applications.
Robust Construction: Chrome steel rings and balls combined with the brass cage create a durable assembly capable of operating within a temperature range of -30° to 110°C, ensuring long-term reliability.
