6307-2RS1/C4GJN8 Bearing Product Overview & Core Advantages
The 6307-2RS1/C4GJN8 is a sealed deep groove ball bearing designed for robust performance in demanding applications. As a single row bearing, it excels at handling radial loads while also accommodating moderate axial loads in both directions. Its key advantages include a C4 radial internal clearance for thermal expansion management in high-temperature operations, and integrated 2RS1 rubber seals on both sides for superior contamination protection and long-term lubrication retention. This combination makes it an ideal, maintenance-free solution for applications requiring high reliability and extended service life.
6307-2RS1/C4GJN8 Bearing Model Code Explained, Specifications & Naming Convention
- 6307: Basic model number indicating a medium-duty deep groove ball bearing with 35mm bore, 80mm OD, and 21mm width.
- 2RS1: Signifies contact rubber seals on both sides of the bearing, providing excellent protection against contaminants and retaining lubricant.
- C4: Indicates a greater radial internal clearance than normal (C0), making it suitable for applications with significant thermal expansion or where interference fits are used.
- GJN8: Denotes the specific polyurea grease filling, optimized for a wide temperature range (-30°C to +120°C) and offering good high-speed performance.
6307-2RS1/C4GJN8 Bearing Structural Features & Performance Benefits
The 6307-2RS1/C4GJN8 delivers superior performance through its carefully engineered design:
- High Reliability Construction: Manufactured from chrome steel for rings, balls, and cage, ensuring consistent performance and durability under various operating conditions.
- Enhanced Sealing Performance: The 2RS1 rubber seals provide effective protection against dust, moisture, and other contaminants, significantly extending bearing life in harsh environments.
- Optimized Internal Clearance: The C4 radial clearance accommodates thermal expansion in high-temperature applications or interference fits, preventing premature failure due to excessive preload.
- Ready-to-Use Lubrication: Pre-filled with GJN8 polyurea grease that maintains stable lubrication across the entire operating temperature range (-30°C to 120°C), supporting the limiting speed of 8,500 rpm.
- Precision Manufacturing: Built to ABEC 1 | ISO P0 tolerance class, ensuring consistent dimensional accuracy and smooth operation for general industrial applications.
6307-2RS1/C4GJN8 Bearing Typical Application Areas
The 6307-2RS1/C4GJN8 finds extensive use across various industrial sectors due to its balanced performance characteristics:
- Electric Motors: Ideal for industrial motors requiring reliable, maintenance-free operation with good speed capability.
- Material Handling Equipment: Conveyor systems, pulley assemblies, and other machinery where contamination protection is critical.
- Agricultural Machinery: Farm equipment, tractors, and implements operating in dusty or harsh environmental conditions.
- Industrial Pumps & Fans: Applications requiring continuous operation with moderate speeds and reliable sealing.
- General Industrial Machinery: Various mechanical systems where a standard deep groove ball bearing with enhanced clearance and sealing is appropriate.
