6309-RS1/C3GJN Bearing Product Overview & Core Advantages
The 6309-RS1/C3GJN is a single row deep groove ball bearing designed for robust performance in demanding applications. This metric bearing excels at handling high radial loads and moderate axial loads in both directions. Its sealed construction ensures protection against contaminants, while the C3 radial internal clearance makes it suitable for applications with thermal expansion or heavy interference fits. Engineered with chrome steel components, it offers excellent durability and a long service life, making it a reliable choice for industrial machinery.
6309-RS1/C3GJN Bearing Model Code Explained, Specifications & Naming Convention
- 6309: Basic model number denoting a single row deep groove ball bearing with a 45mm bore, 100mm OD, and 25mm width.
- RS1: Signifies a contact seal made of Nitrile Rubber (NBR) on one side, providing effective protection against dust and moisture ingress.
- C3: Indicates a greater radial internal clearance than the Normal (CN) group. This is ideal for applications involving high speeds or where thermal expansion of the shaft and housing is expected.
- GJN: Designates a filling slot on the outer ring and the use of a polyamide 66 cage. The cage is lightweight and contributes to smooth operation at high speeds.
6309-RS1/C3GJN Bearing Structural Features & Performance Benefits
Robust Sealed Design: The RS1 contact seal effectively shields the bearing internals from contaminants, enhancing reliability in harsh environments and reducing maintenance needs.
Optimized Internal Clearance: The C3 clearance accommodates thermal expansion and interference fits, preventing premature failure due to excessive preload and ensuring stable operation under varying thermal conditions.
High-Speed Capability: The lightweight polyamide 66 cage (GJN) minimizes centrifugal forces, allowing for a high limiting speed of 6,700 rpm and ensuring smooth, low-vibration rotation.
High Load Capacity: Manufactured from high-grade chrome steel, this bearing offers a high dynamic load rating of 11,915 lbf and a static load rating of 7,194 lbf, providing dependable performance under significant radial stresses.
6309-RS1/C3GJN Bearing Typical Application Areas
This versatile bearing is commonly specified in:
- Electric Motors and Gearboxes
- Industrial Pumps and Compressors
- Material Handling Equipment (e.g., conveyor rollers)
- Agricultural Machinery
- General Industrial Machinery requiring reliable, sealed bearing solutions.
