7315 BECBJ Bearing Product Overview & Core Advantages
The 7315 BECBJ is a single row angular contact ball bearing engineered for precision applications requiring high rotational accuracy and 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 reliable operation in high-speed applications with a limiting speed of 5,300 rpm. Its robust construction using chrome steel rings and balls, combined with a stainless steel cage, ensures high rigidity and long service life, making it ideal for demanding industrial environments.
7315 BECBJ Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7315 | Standard bearing series designation indicating a 75 mm bore, 160 mm outside diameter, and 37 mm width. |
| BE | Designates a 40° contact angle and optimized internal geometry for high axial load capacity. |
| CB | Indicates a stainless steel cage construction, providing excellent strength and corrosion resistance for high-speed operation. |
| J | Specifies that the bearing is pre-lubricated with grease for immediate use and reduced maintenance requirements. |
7315 BECBJ Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single row design with a 40° contact angle provides optimal internal geometry to handle combined radial and axial loads effectively. The robust chrome steel construction ensures dimensional stability under load.
- High-Speed Performance: The lightweight stainless steel cage minimizes centrifugal forces, contributing to the high limiting speed of 5,300 rpm. The optimized internal clearances and precision manufacturing to P6 tolerance ensure smooth operation at high velocities.
- Precision Engineering: Manufactured to P6 (ABEC-3) tolerance class with tight dimensional controls on bearing dimensions (bore, OD, width), ensuring precise fitment and minimal runout in critical applications.
- Ready-to-Use & Durable: The bearing comes pre-lubricated, allowing for immediate installation. The combination of high-grade chrome steel components and a corrosion-resistant cage offers excellent durability across a wide temperature range (-30° to 110 °C).
