6304-2RSH/C3GJN Bearing Product Overview & Core Advantages
The 6304-2RSH/C3GJN is a single row deep groove ball bearing engineered for high reliability in demanding applications. Its sealed construction provides robust protection against contamination, making it ideal for environments where maintenance access is limited. This bearing is designed to primarily handle radial loads efficiently while also accommodating moderate axial loads in both directions. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers consistent performance and long service life, supported by a C3 radial internal clearance suitable for applications with thermal expansion considerations.
6304-2RSH/C3GJN Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Benefit |
|---|---|---|
| 2RSH | Double Contact Seals (NBR Rubber) | Provides superior sealing effectiveness against dust and moisture ingress compared to standard seals |
| C3 | Greater than Normal Radial Internal Clearance | Accommodates thermal expansion in applications with elevated operating temperatures |
| GJN | Grease Filling (Polyurea Thickened) | Provides optimized lubrication for the bearing's operational temperature range (-30° to 120°C) |
6304-2RSH/C3GJN Bearing Structural Features & Performance Benefits
Optimized Sealing System: The 2RSH double contact seals create an effective barrier against contaminants while maintaining low friction characteristics. This design significantly extends bearing life in contaminated environments.
Robust Load Capacity: With a dynamic load rating of 3574 lbf and static load rating of 1765 lbf, this bearing delivers reliable performance under substantial radial loads while handling moderate axial loads in both directions.
Thermal Stability: The C3 clearance provides additional internal space to accommodate shaft expansion under thermal loads, preventing premature failure due to excessive preload.
High-Speed Capability: The limiting speed of 14,000 rpm demonstrates excellent high-speed performance, supported by precision-ground chrome steel components and optimized cage design.
6304-2RSH/C3GJN Bearing Typical Application Areas
- Electric Motors: Ideal for various motor applications requiring sealed bearings with reliable performance
- Industrial Gearboxes: Suitable for gearbox applications where contamination protection is critical
- Material Handling Equipment: Conveyor systems, pulleys, and other machinery requiring durable bearing solutions
- Agricultural Machinery: Implements and equipment operating in demanding, dusty environments
- HVAC Systems: Fans, blowers, and other components requiring maintenance-free operation
