6307-2RSJ Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 6307 | Basic bearing series and size designation (35mm bore, 80mm OD, 21mm width). |
| 2RS | Bearing is equipped with two contact seals, one on each side, offering superior protection from dust and moisture. |
| J | Indicates a pressed steel cage, which is a lightweight and robust design suitable for high-speed operation. |
6307-2RSJ Bearing Structural Features & Performance Benefits
- Superior Sealing: The 2RS designation signifies double-lipped contact seals. These seals effectively retain lubrication and exclude contaminants, significantly extending bearing service life in harsh environments and reducing maintenance needs.
- Optimized Cage Design: The pressed steel cage (J suffix) ensures stable operation at the bearing's limiting speed of 8,500 rpm, providing excellent guidance for the balls with minimal friction.
- Robust Load Capacity: With a dynamic load rating of 7509 lbf and a static load rating of 4339 lbf, this bearing is built to handle significant radial forces in continuous operation.
- High-Quality Construction: All core components—rings, balls, and cage—are manufactured from chrome steel, ensuring high strength, wear resistance, and consistent performance.
6307-2RSJ Bearing Typical Application Areas
This bearing is widely used across various industries due to its sealed and robust design. Common applications include:
- Electric Motors and Generators
- Industrial Gearboxes and Power Transmission Systems
- Agricultural Machinery
- Material Handling Equipment (e.g., Conveyors)
- Pumps and Fans
- Automotive Components (e.g., alternators, idlers)
