7308 BE-2RZP Bearing Product Overview & Core Advantages
The 7308 BE-2RZP is a single row angular contact ball bearing engineered for high-performance applications requiring precision and reliability. Its design is optimized to handle significant combined loads, accommodating both radial and substantial one-direction axial loads simultaneously. Featuring a sealed construction with high-performance lubrication, this bearing is designed for high-speed operation and offers excellent operational stability and long service life, making it an ideal choice for demanding industrial environments where precision and durability are paramount.
7308 BE-2RZP Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Significance & Advantage |
|---|---|---|
| BE | Increased internal clearance / contact angle optimization | Optimized for specific preload and thermal expansion conditions, enhancing performance under high-speed operation. |
| 2RZ | Non-contact rubber seals on both sides | Provides effective protection against contaminants while minimizing friction, contributing to the high limiting speed. |
| P | Glass fiber reinforced nylon cage (P cage) | Offers low weight, excellent acceleration characteristics, and is suitable for high-speed applications, contributing to reduced friction and heat generation. |
7308 BE-2RZP Bearing Structural Features & Performance Benefits
Optimized Internal Geometry & High Rigidity: The 40° contact angle and precision-ground raceways are designed to support high axial loads from one direction and radial loads effectively. This geometry provides high rigidity and stable rotational accuracy, which is critical for precision machinery.
Superior Load Capacity: With a dynamic load rating of 10395 lbf and a static load rating of 6862 lbf, this bearing is built to handle significant combined loads in demanding applications.
High-Speed Performance: The combination of the lightweight nylon P cage and non-contact 2RZ seals allows for a high limiting speed of 7,500 rpm. The factory-applied lubrication is specifically chosen to maintain performance at these elevated speeds.
Sealed & Pre-Lubricated for Longevity: The bearing is supplied with grease and sealed on both sides (2RZ), making it a maintenance-free unit for the majority of its service life. This design effectively retains lubrication and excludes contaminants, ensuring reliability and reducing total cost of ownership.
7308 BE-2RZP Bearing Typical Application Areas
