7306 BE-2RZP Bearing Product Overview & Core Advantages
The 7306 BE-2RZP is a single row angular contact ball bearing designed for high-performance applications requiring precision and reliability. Engineered to accommodate combined loads, it efficiently handles significant radial loads and axial loads in one direction simultaneously. Its 40° contact angle provides excellent axial load capacity and high rigidity. The bearing features sealed construction and comes pre-lubricated, offering long-term, maintenance-free operation. Manufactured to P6 (ABEC-3) tolerance class, it ensures smooth running and high rotational accuracy, making it ideal for demanding industrial environments.
7306 BE-2RZP Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| BE | Designates a 40° contact angle and optimized internal geometry for high axial load capacity. |
| 2RZ | Indicates non-contact seals on both sides. These seals provide effective protection against contaminants while minimizing friction, contributing to the high limiting speed. |
| P | Signifies that the bearing is supplied with a standard performance grease suitable for the specified temperature range. |
7306 BE-2RZP Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The single row design with a 40° contact angle provides robust support, enabling the bearing to handle high combined loads effectively. The optimized raceway and ball geometry maximize load distribution.
- Precision and High-Speed Performance: Manufactured to P6 tolerance class, the bearing ensures minimal runout and vibration. The combination of the nylon cage and low-friction 2RZ seals allows for a high limiting speed of 9,500 rpm, making it suitable for high-speed applications.
- Long Service Life and Maintenance-Free Operation: The sealed construction effectively shields the precision-ground chrome steel components from dust and moisture. Pre-lubrication ensures consistent performance throughout its service life, reducing the need for maintenance.
7306 BE-2RZP Bearing Typical Application Areas
This angular contact ball bearing is widely used in precision machinery and high-speed equipment, including:
- Machine Tool Spindles
- High-Speed Pumps and Compressors
- Precision Gearboxes
- Industrial Automation and Robotics
- Electric Motors
