6307-2RS1/GJN Bearing Product Overview & Core Advantages
The 6307-2RS1/GJN is a metric single row deep groove ball bearing designed for exceptional reliability in demanding applications. Its core advantage lies in its sealed construction (2RS1), which provides robust protection against contamination, and its optimized radial load capacity. This bearing is engineered to deliver high performance with a limiting speed of 8,500 rpm and is manufactured to ABEC 1 | ISO P0 tolerance standards, ensuring consistent quality and smooth operation. It is an ideal solution for applications requiring a balance of performance, durability, and maintenance-free operation.
6307-2RS1/GJN Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Benefit |
|---|---|---|
| 6307 | Basic bearing series designation, indicating a medium duty, single row deep groove ball bearing with a 35mm bore, 80mm OD, and 21mm width. | Defines the core dimensions and type. |
| 2RS1 | Contact rubber seals on both sides of the bearing. | Provides excellent protection against contaminants and retains lubricant, enabling maintenance-free operation. |
| GJN | Indicates the bearing is filled with a specific, high-quality polyurea-thickened grease. | Offers stable lubrication performance across the specified temperature range (-30°C to 120°C), contributing to long service life. |
6307-2RS1/GJN Bearing Structural Features & Performance Benefits
- Robust Sealed Design: The 2RS1 contact seals are a critical feature, effectively shielding the internal components from dust, moisture, and other particulates. This significantly enhances bearing life in harsh environments and makes it a maintenance-free component.
- High Load Capacity: Manufactured from high-grade chrome steel for both rings and balls, this bearing offers a high dynamic load rating of 7509 lbf and a static load rating of 4339 lbf, providing reliable support for substantial radial loads.
- Optimized for Smooth Operation: The combination of a chrome steel cage, precision ABEC 1 (ISO P0) tolerances, and standard (CN) radial internal clearance ensures low vibration, quiet running, and consistent performance, making it suitable for a wide range of industrial applications.
- Ready-to-Install Convenience: The bearing is pre-lubricated with grease (GJN), eliminating the need for initial lubrication and simplifying the installation process.
6307-2RS1/GJN Bearing Typical Application Areas
