6304-2RS1NR/C3GJN Bearing Product Overview & Core Advantages
The 6304-2RS1NR/C3GJN is a single row deep groove ball bearing designed for robust performance in demanding applications. This metric bearing excels in handling radial loads and offers high operational reliability. Its key advantages include a sealed design for contamination protection, a snap ring groove on the outer ring for simplified axial location, and a C3 radial internal clearance suitable for applications with thermal expansion or interference fits. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides consistent precision and is ideal for general industrial use where durability and ease of installation are paramount.
6304-2RS1NR/C3GJN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6304 | Basic bearing series, indicating a single row deep groove ball bearing with a 20mm bore, 52mm OD, and 15mm width. |
| 2RS1 | The bearing is fitted with contact seals on both sides. This provides superior protection against dust and moisture ingress compared to non-contact shields. |
| NR | The outer ring features a snap ring groove. This allows for secure axial location within a housing without the need for complex housing shoulders, simplifying assembly and reducing costs. |
| C3 | Specifies a greater than normal radial internal clearance. This is beneficial in applications where thermal expansion, shaft interference fits, or heavy loads are expected, preventing premature failure due to excessive preload. |
| GJN | Indicates the bearing is pre-lubricated with a specific grease suitable for the stated temperature range of -30°C to 120°C, offering long-term, maintenance-free operation. |
6304-2RS1NR/C3GJN Bearing Structural Features & Performance Benefits
Robust Construction: Manufactured entirely from chrome steel for rings, balls, and cage, this bearing ensures high strength, wear resistance, and a long service life under radial dynamic loads up to 3574 lbf.
Enhanced Sealing & Protection: The double-sided contact seals (2RS1) effectively retain grease and exclude contaminants, making the bearing ideal for dirty or humid environments and contributing to its maintenance-free characteristic.
Simplified Installation & Axial Location: The integrated snap ring groove (NR) on the outer ring eliminates the need for complex housing designs, allowing for secure mounting and reducing overall assembly time and cost.
Optimized Internal Clearance: The C3 clearance provides operational stability in applications prone to thermal expansion or where tight interference fits are used, preventing binding and ensuring smooth rotation.
6304-2RS1NR/C3GJN Bearing Typical Application Areas
This versatile bearing is commonly specified in a wide range of industrial machinery and equipment, including:
- Electric Motors and Gearboxes
- Industrial Fans and Blowers
- Material Handling Conveyors
- Agricultural Machinery
- Automotive Components (e.g., alternators, idler pulleys)
